Juniper Switches vs. Routers: Which one is Right for Your Network?
Juniper is one of the popular IT networking brands, especially for its switches and routers.
As routers and switches are the connecting devices in a network, people assume them to be the same. Often, people buy them interchangeably thinking their work will be done. But, the fact is routers and switches have different functionality. So, if you want a seamless network connection, choose the right option between the two.
In this post, we will discuss what routers and switches are, how they function, and how they are different.
What are routers and switches?
Switches provide the facility to share information & resources by connecting different networking devices, such as computers, printers, and servers. The connected devices share data and information and communicate with each other. Usually, switches are used in a small business network setup.
Routers connect switches and their corresponding networks, building a large network. The switches and networks can be in a single location or different locations. Compared to switches, routers are smarter. They distribute or route the internet connection from the modem to all networking devices.
The two major functions of routers are to create and maintain the local area network and manage the entering and leaving of data.
How do routers and switches work?
A unique Media Access Control or MAC address plays an important role in the functioning of the switches. Switches put the IP Packet, which is sent by a device or computer to another device, with the source MAC address and destination MAC address. Other than this, switches encapsulate the IP Packet with a Frame and then send it to another device.
Routers work by connecting various networked devices, such as PC, tablets, printers, etc., to the network and form a network. First, the routers connect the modem to other devices, allowing communication between the devices and the internet.
Later, the routers transmit the data packets with the defined IP address from one network to another or within a network by providing a local IP address to each device over the internet. The local IP address ensures that data reaches the right place and does not get lost within the network. Routers find the best and fastest path to send data packets to the devices connected within the network. It’s very similar to the delivery package.
What are the benefits of routers and switches?
Switches enhance the available bandwidth of the network, enhance the performance of the network, reduce the workload on the individual host such as PCs, can be directly connected to the workstations or devices, and have less frame collision.
Routers enable most networking devices to connect easily at any time, can connect with the different architectures of the network, provide highly secure network access with password protection, reduce the network traffic with the help of the collision feature and provide data packets to correct destinations with the best route using the routing table and intelligence.
How are routers and switches different?
- Switches connect the end devices, such as computers, printers, etc; whereas, routers connect two different networks.
- Switches work on the data link layer of the OSI model, but routers work on the network layer of the OSI model.
- Switches determine the destination address of the received IP packet and forward it to the destination address. But, routers find the smallest and best routes for the packets to reach the destination. This is determined using the routing table.
- Switches use various switching techniques, such as circuit switching, packet switching, and message switching; whereas, routers use two routing techniques. The two techniques are adaptive routing and non-adaptive routing.
- Switches store MAC addresses in the lookup table or CAM table, getting the source and destination addresses. On the other hand, routers store the IP addresses in the routing table.
Which are popular Juniper routers and switches?

How to Choose an IP Phone for a System for Small to Medium Businesses?
Almost all businesses have adopted cloud VoIP as part of their communications strategies due to their many benefits. However, if you own a small to medium business, it can be difficult to decide which IP phone system is best for your needs.
With so many features and options available, it’s hard to determine which one is the most cost-effective and reliable. However, the right IP phone system can help you to streamline operations and improve communication between employees and customers.
The first step in any Cloud VoIP deployment is to determine where VoIP handsets will be needed, what type of handset you want to use, and if supporting infrastructure is available or not.
What is a VoIP Phone?
Voice over Internet Protocol (VoIP) phone is a type of telephone system that uses an internet connection to make and receive calls. It’s also known as a Voice over IP (VoIP) phone system, an Internet phone system, or an IP phone system.
This type of system is becoming more popular for businesses, as it’s often more affordable and easier to set up than traditional landline phone systems.
VoIP phone systems work by sending the audio signal of each call over the internet, rather than through a physical phone line. This allows you to use any internet-connected device, such as your computer or smartphone, as your VoIP phone. It also eliminates the need for long distance calling fees, since the call is routed through the internet instead of the traditional phone network.
Networking and Power
When it comes to choosing an IP phone system for small to medium businesses, it’s important to consider the networking and power requirements. The IP phones you select need to be able to run off of your business’s existing network, and they need to be able to connect to power outlets.
When it comes to networking, you should make sure the phones are compatible with your current network infrastructure. This includes checking that the phones have the right ports, protocols, and other components necessary for them to work on your network.
If your network is a wireless one, then you need to make sure that the phones have the right wireless protocols in order to connect to your Wi-Fi. Additionally, check if your router or switch has enough ports to connect all the phones.
As for power, you need to make sure that the phones have power outlets close enough to them for them to work properly. For businesses that don’t have power outlets near the phones, there are many models that offer PoE (Power over Ethernet) which allows you to power the phones through the Ethernet cable.
Finally, it’s important to think about how much power your chosen phones will draw from your power sources. You want to make sure that you won’t be overloading your system by powering too many phones at once.
Overall, make sure that you take into account the networking and power requirements when selecting an IP phone system for your business. This will help ensure that your system runs smoothly and that your business isn’t suffering from any network issues.
Selection of a Handset
When selecting an IP phone system for a small to medium business, it is important to choose the right type of handset. This includes selecting between physical handsets and ruggedized handsets.
Physical handsets are the most common type of IP phone and can be used in both home and office environments. These handsets typically come in standard sizes and are usually feature-rich.
They usually have color screens, full-duplex audio, backlit buttons, and multiple lines that allow for multiple simultaneous calls. Physical handsets are typically designed for use in non-rugged environments, making them an ideal choice for offices, businesses, and other places that don’t require extra protection from dust and water.
Ruggedized handsets are designed for use in more extreme environments where there is a need for additional protection from dust, water, and other debris. These handsets are designed with special weatherproof cases that protect against accidental damage.
They also typically include more durable components like reinforced buttons and LCD displays that are better suited for harsh conditions. Ruggedized handsets are typically more expensive than standard physical handsets, but they offer extra protection and durability in rough environments.
Why You Need a VoIP Business Phone Service
VoIP (Voice over Internet Protocol) business phone services offer a reliable and cost-effective way for small to medium businesses to keep in touch with customers, suppliers, and employees. By taking advantage of Voice over Internet Protocol (VoIP), small to medium businesses can save money on phone bills while still receiving the same quality of service.
For example, VoIP services provide call forwarding, conference calling, and other features that enable businesses to increase productivity and keep their customers connected.

Do you need a license for the Fortinet firewall?
Fortinet Firewall is undoubtedly one of the best firewalls in the networking industry. This is why companies (both MNCs and SMEs) are unhesitatingly using it. Compared to other brands, Fortinet better protects the network from unwanted traffic. It easily detects and stops them, securing the network as well as the organization.
Fortinet firewall is strong, but not enough to capture the hostile traffic that comes in many different forms. So, licensing is important. It’s a way of picking the level of protection you desire. You can get basic as well as total protection after licensing. With a valid license, the Fortinet firewall becomes stronger to protect the network from unwanted traffic.
The common licensing options available for Fortinet firewall are FortiGuard and FortiCare. There are other catchy names for Fortinet’s license products. Also, it depends on the service provider you are connecting with for the license.
Not only protection, but licensing enables various features on the Fortinet firewall. The difference depends on the license for a hardware firewall and a virtual/software firewall of Fortinet.
Will Fortinet Firewall not function without a license?
Just like other firewalls, Fortinet firewalls include a base license. It means the firewall will function without any kind of additional licensing. If you don’t want to spend extra on your network security, you can work with the basic license. The only thing is you will get basic features and minimum protection. The security level will not be strong and hostile traffic will not be controlled.
The license and the additional features that come along are purchased like subscriptions. Typically, the licensing subscription is offered in yearly or two-year increments.
What does a base Fortinet license include?
As already mentioned, a base license gives Fortinet firewall basic features, which include Application Control and SSL Inspection. Other than this, a base license offers WAN Optimization, Unlimited VPN clients, and so on. The features vary from vendor to vendor.
Some licensing vendors provide Network Firewall, SSL and IPSec VPN and complete wireless protection.
Explaining with an example:
FortiGate, provided by one vendor, gives you IPS functions, URL Filtering, VPN tunnels, VIPs, routing protocols, DPI, and so on. But, you do not get an update from FortiGuard and you won’t be entitled to contact support. Also, you won’t get updates on firmware or FortiGuard features.
What will Fortinet firewall licensing offer you?
With additional Fortinet firewalls, you will get features like more advanced Malware Protection, Advanced Threat Protection, and Remote Access. Other than this, there will be features like Antivirus, Application Control, Vulnerability Scanning, and Web Filtering. The story doesn’t end here. You also get full-automated updates, AntiSpam, and Web Application Firewall.
As already mentioned, the features and add-ons differ from one vendor to another. You cannot expect a vendor to offer services similar to another vendor.
Why is it important to take advantage of additional security features?
We know you would not want to spend on security features that you are not sure of. But, this is something important for your organization. It’s because basic features with a basic license will give you limited benefits only.
You need to consider your ongoing needs before getting a license for your Fortinet firewall. The thing is that your organization will be a mess without professional support. With a license, you will always have professionals by your side. This will increase your security level and prevent vulnerability of your network.
If you are thinking about automatic firmware and security updates, consider their positive aspects. They might not be effective on a large scale, but they are critical for your IT infrastructure.
Is getting a Fortinet firewall license cost-effective?
Yes, the Fortinet firewall license is cost-effective in the long run.
Initially, you might find it costly. But, if you compare the cost and features offered, you will understand the worthiness of the license. The vendor support and firmware updates will keep your network up to the mark, protecting it in every way. This will secure your important data, which is the foundation of your organization. If the data gets lost, you will poorly suffer financially. This is why a Fortinet firewall license is cost-effective.
We know you can function with basic features that come with the basic license and you might not need the highest level of protection. But, there is nothing wrong with considering more than just basic firewall protection other than the cost. This will add too much to your Fortinet firewall and increase its ability in every way.
If you keep the cost aside, you will understand the importance of the license and its add-on features. Also, you will understand how the license will help your organization grow securely. You should do your research and make your decision accordingly.
What costs are involved in purchasing a Fortinet firewall license?
The upfront cost and the renewal cost. Other than this, you might have to pay for upgrading the package if required. This becomes crucial if you want extra protection and it isn’t getting fulfilled with the current package.
The cost might vary from vendor to vendor and the features offered by them. So, before investing in the license, you should compare the vendors and discuss the features. Make sure the features are as per your network security requirements. If they conflict, the investment will not be worth it.

Can you connect a managed and unmanaged switch?
Managed and unmanaged are two very different forms of network switches. Connecting and bringing them on the same platform is always doubtful because the features and their working models are at two ends. But, users always try this combination for multiple benefits.
In this post, we will try to answer this question. But, before that, we will explain managed and unmanaged switches briefly.
Managed Switches
Considered “smart switches”, the managed switches bring a high level of intelligence to the network. As the name suggests, it’s possible to manage, configure, monitor, and troubleshoot issues with your network using managed switches. One of the distinctive features of managed switches is that every switch has its own IP address for identification and addressing. Using managed switches, you can choose ideal operating parameters for the ports of your network.
Managed switches provide a layer of security, monitoring, and controlling network events, shutting down detected threats, preventing unauthorized access, and encrypting communication. Other than this, the switches feature built-in redundancy, duplicating the data and recovering it easily if a device or network fails.
Use of managed switches
If you require a response time of milliseconds, the managed switches are for you. The managed switches are suitable for organizations that manage and troubleshoot their network remotely and securely as the switches allow the network managers to reach optimal network performance and reliability.
You can use managed switches on any network or a segment of a network where you want to monitor and control traffic. You can have complete control of data, bandwidth, and traffic control in whichever network you use the managed switches.
Unmanaged switches
Unlike managed switches, unmanaged switches serve only one purpose. They provide Ethernet devices with network connections, helping them to communicate with one another. These switches don’t offer intelligence like managed switches; they only add additional ports to your networks and this is why they are known as “the man in the middle”. They are not even visible in the network infrastructure.
As there is configuration or setup required, you cannot control traffic using unmanaged switches. They are simple plug-and-play. In most cases, unmanaged switches are deployed.
In simple words, unmanaged switches don’t offer features like managed switches, so they are inexpensive. If you want features and are not worried about cost, consider managed switches only.
Read about: How Can I Set Up a Dell Managed Switch?
Use of unmanaged switches
Mostly, unmanaged switches are used to connect edge devices on network spurs or a small stand-alone network with only a few components. If you want to simplify the installation of wireless access points and IP-based surveillance cameras in your business network, you should choose unmanaged switches.
Other than this, unmanaged switches are recommended for homes, and small businesses or to add temporary workgroups to larger networks.
Combination of managed and unmanaged switches
Unmanaged switches use a standard configuration, while managed switches provide add-ons on top of the configuration allowance. If you are using unmanaged switches, you cannot change them. They are functional only to an extent of establishing a network, with no or little technical help in setting up the network.
With managed switches, you get tools to monitor, configure and improve the performance of the network, ensuring stability and consistency.
This means you cannot combine unmanaged switches with managed switches but can combine managed switches with unmanaged switches. It’s a very tricky situation.
As managed switches allow configuration flexibility, their combination with unmanaged switches is possible. If you operate the managed switch in “Open mode” having no configuration set up, the device will be set up to the default VLAN. The default VLAN means all the ports are members of the default VLAN.
Default VLAN with ports allows easy connection or combination with unmanaged switches. You don’t have to make further changes to your network infrastructure. But, everything depends on the network design and recruitment of your organization.
Because of this reason, experts prefer investing in managed switches. Whenever required, you can change the configuration and allow a combination of unmanaged switches. You can plan the section of your network you want to meet specific networking needs.
The story is not the same for all managed switches. So, you should confirm this feature before investing.
Is it good to combine managed and unmanaged switches?
Combining managed and unmanaged switches means one default VLAN across both switches with some additional configuration for unmanaged switches. If this on VLAN generates a lot of traffic, the bandwidth could become a problem for you. So, it’s better to spread the VLAN across switches and avoid any bandwidth issues.
What more should you know about combining managed and unmanaged switches?
As already mentioned, combining managed and switches is a bit tricky as they function differently. But, if you are using managed switches and want to combine them with unmanaged switches for any reason, you should seek help from IT experts. You should do as they say because of the proper combination and the best network infrastructure in your organization.

Can I connect the PoE switch directly to NVR?
IP cameras serve multiple purposes; they are employed in all modern video networks for surveillance purposes, and to record and store visual data. But, this is only possible if Network Video Recorder or NVR is used along with IP cameras.
The NVR has a major role to play in the functioning of IP cameras. But, it cannot be utilized without the Power of Ethernet or PoE. Without PoE, the NVR has no Ethernet ports on the back panel to establish a direct connection with the IP cameras. This is where an external PoE switch comes into the picture. The connection is established between a PoE switch and NVR to operate IP cameras. It means a PoE switch can be directly connected to NVR.
Before we discuss how to set up a PoE switch with NVR, we will talk a bit more about NVR and how it is different from a PoE switch.
About Network Video Recorder
When NVR is integrated with PoE transmission protocols, it’s known as PoE NVR. It offers centralized controls for video or image management and storage. To form a managed Poe NVR network, the NVR technology is integrated with PoE switches.
The connection of PoE and NVR enables the transmission of electronic data and power over an Ethernet Cable. Sometimes, multiple switches are integrated for the increased number of powered devices. It’s because data distribution is performed by PoE switches.
When integrated, the PoE switches deliver video data to a specific IP address under the PoE NVR.
Difference between PoE switches and PoE NVR
NVR is an advanced video signal processing technology, while PoE switches act as an intermediate device. If only PoE switches are utilized in the Ethernet network, they will only allow managed networking and data transmission. On the other hand, PoE NVR benefits by enabling remote IP addresses and controlling video data transmission, processing and storage. This improves the quality of the video transmission network.
By now, you might have understood PoE switches and NVR functions and why connecting them will be beneficial for video networking, especially IP cameras. Next, you should learn to connect them.
How should you configure PoE switches with NVR?
As already mentioned, the PoE switches are configured with NVR for two important purposes. The purposes are to reduce Ethernet video transmission network complexity and get extra numbers of ports for transmission. The configuration is done accordingly so that these two purposes are fulfilled.
Configuration to reduce complexity:
- Start with interconnecting the NVR and PoE routers. Generally, the plug and play connectivity is available between NVR and routers. If it’s not available, you should follow the steps discussed in the product manuals.
- Get one or more PoE switches based on your requirements. You should connect the PoE switch to the LAN port of the PoE router using an Ethernet cable. Next, you should connect a power cable to the power outlet of the PoE switch.
- Next, connect the IP cameras to ports. See the number of ports on the PoE switches before the cameras to them. Typically, 1 to 8 switches are available. Connect cameras to ports properly.
- Last, connect IP cameras and a PoE NVR router. Here, operators often get confused. To operate IP cameras, you cannot skip connecting them to the NVR and router. The IP cameras should be interlinked with the PoE NVR router so that centralized control and video recording are enabled.
The configuration of PoE switches to NVR is complete. Now, turn on the power supply to the PoE router. This will eventually power NVR and PoE switches, allowing transmission regularly as NVR does.
With this configuration, video transmission from multiple IP cameras using a single Ethernet cable takes place, reducing the complexity of the network. The best part is that this configuration doesn’t require any external power sources or power wires.
Configuration to get more ports
- Sometimes, high-configuration switches with multiple ports are more in demand. Such applications or setups have nothing to do with complexity. To add more ports to the networking structure, follow the below-mentioned steps.
- Start with finding a PoE switch that has 1 to 8 ports and connecting IP cameras to it. Connect the selected PoE switch to the local area network or LAn. With this, the PoE switch will work as a hub or a common switch.
- The next step is a bit complicated. First, connect the hub or command port to the PoE router. Then, connect another PoE switch with 1 to 8 ports to the hub switch through an open port. Once you establish this connection, the number of PoE ports will increase to 15. Simply explained, the 7 utility ports of the hub switch and 8 ports of the secondary PoE switch.
- Last, connect the NVR with the PoE router, ensuring all the cameras are interlinked to NVR.
The configuration of PoE switches with NVR is complete. You can turn on the power to start the operations.
What else should you know to connect PoE switches with NVR?
The IP cameras, NVR routers, and PoE switches should be compatible with one another. Other than this, make sure you use quality products to avoid future problems like switch malfunction, network breakdown, etc.
For quality products, you should buy them from trusted suppliers like Gear Net Technologies. To know more about the products, please Whatsapp us at +971585811786.
A Guide on How to Configure Cisco ASA to Juniper SRX Site-to-Site VPN
In this blog, we will discuss what Cisco ASA and Juniper SRX are and how to configure both for site-to-site VPN.
What is Cisco ASA? What does ASA do?
Cisco Adaptive Security Appliance (ASA) is a security device that combines the functioning of a firewall, antivirus, intrusion prevention, and virtual private network (VPN). It provides you with proactive protection by stopping attacks before they spread through the network.
The term Cisco ASA is an umbrella term for the family of security devices by Cisco that protects corporate networks and data centers of all sizes. Using Cisco ASA allows companies to get highly secure access to data and network resources.
Cisco ASA Software is the core operating system that comes in the family of Cisco ASA devices. It is known to deliver enterprise-grade firewall protection for ASA devices in a wide range of form factors, such as standalone appliances, blades, and virtual appliances for any distributed network environment.
Additionally, it also comes with integrated IPS, VPN, Unified communications, and various other capabilities.
What is Juniper SRX? What does SRX do?
Juniper Networks SRX Series Services Gateways are high-performance network security devices for enterprises and service providers that provide routing, networking, and security capabilities. The SRX Series combines the functionality of a next-generation firewall, application visibility and control, IPS, and other security services. It is designed to provide complete security to protect and control business resources and assets.
Juniper SRX devices offer high port density, advanced security, and flexible connectivity. Based on Junos, SRX gateways allow you to deliver secure and manageable networks of up to thousands of sites. The combination of routing, WAN connectivity, switching, and unified threat management (UTM), which include services such as antivirus, anti-spam, URL filtering, firewall/VPN, and App Secure simplifies the deployment and administration while delivering fast and consistent service quality, no matter where a user is located.
What is a Site-to-Site VPN? Why do we need to create a Site-to-Site VPN?
Site-to-site VPNs are virtual private networks available for secure use between different sites and are widely used by various organizations around the world. Technically, a site-to-site VPN provides a single corporate WAN to support secure cross-site communication by creating an encrypted link between VPN gateways located at each site, even when sites are geographically separated.
Site-to-site VPNs offer a wide range of benefits, such as:
- Encrypted traffic for secure connectivity so that any business data crossing over the public Internet remains protected from eavesdropping and modification
- Simplified network architecture as traffic from one LAN to another remains internal, which means all sites can use internal addresses for each other’s resources
- Access control rules are easier to define because any traffic that is not emerging from inside the network or entering via VPN tunnels can be blocked from accessing business resources
How to Configure Cisco ASA to Juniper SRX Site-to-Site VPN

7 Advantages of Using a Juniper Switch Over Cisco
In the enterprise networking space, Juniper Networks has been outpacing Cisco Systems. How do the products and strategies of the two companies compare? And why are they the best option for your data center hardware? Before delving into the differences between Cisco and Juniper switches, it is essential to understand the importance of a switch.
What is a Switch?
Switches are the most essential components of any network. They connect several devices on the same network, such as PCs, wireless access points, printers, and servers, within a building or campus. A switch allows connected devices to share information and communicate with one another. A switch allows numerous devices to use a network while keeping each device’s traffic from interfering with the traffic of other devices. At a busy crossroads, the switch serves as a traffic cop. When a data packet arrives at one of its ports, the switch identifies which way it is going. It then routes the packet to its destination via the appropriate port.
The switch understands which network devices are connected to it and can move data packets directly between those devices. In other circumstances, data packets may be routed to distant destinations on different networks. In this case, a switch forwards the packets to a router, which then forwards them to their network destinations.
Cisco vs Juniper: Which Switch is Better?
After dominating the commercial networking market from the mid-1980s to the 2000s, Cisco began to lose market share due to the introduction of alternative network equipment brands. Today, more and more organizations, particularly those on the smaller side, are looking at their networking options and questioning if Cisco is the only product worth investing in.
Juniper Networks has swiftly grown in recent years, challenging Cisco as the brand of choice for an increasing number of organizations. Coming from a time when Cisco had a monopoly, they have expanded to hold about 30% of the market in a little more than a decade.
So, why should your company consider investing in a Juniper switch rather than a Cisco one for its networks? Let’s have a look at some of the reasons why.
-
Better Products for Small-to-Medium-Sized Businesses
Juniper was one of the first companies to notice that smaller companies were largely excluded from high-end networking due to Cisco’s monopolistic pricing. As the Internet evolved and spread, and global data-based telecommunications became the norm, smaller businesses required equipment to keep up.
For the major players in the business, Cisco equipment is probably still the best available even if it is at the highest price tiers and combines their proprietary hardware, software, and support features. Juniper, on the other hand, makes a lot more sense for everyone else.
-
Established to Overcome Cisco
Juniper was a company with a mission. They were created as a combined company by unhappy venture capitalists and dissatisfied Cisco consumers. They viewed Cisco in the late 1990s as being sidetracked and not looking into the Internet’s possibilities for business networking. Given that Juniper was the first opponent to breach Cisco’s defenses, it seems that they did well.
Juniper provides greater flexibility to organizations by providing interfaces that do not require the usage of a Certified Expert. It’s all about the customer.
-
Extensive Research Focus
Cisco paid a heavy price for its lack of vision. It stopped looking ahead to new technologies and became preoccupied with simply maintaining its large networking market share. Companies such as Juniper were pioneers in virtualization and remote office assistance. Since then, Cisco has been playing catch-up, and it shows in their everyday services. They lack the forward-thinking features that smaller enterprises require.
-
A Commitment to Network
Unlike Cisco, Juniper did not become bogged down in the 2000s by a succession of questionable investments in non-networking sectors. While Cisco was investing in things like cable-top TV boxes – 20th Century technologies – their competition was primarily focused on improving business networking. It’s evident in their products.
A Juniper switch is specifically built for enterprises wishing to transition away from traditional copper wire solutions and into virtual and cloud environments.
-
High Prices for Cisco Kit
Many of these issues would be more academic if Cisco products were not so expensive. They are just out of reach for many enterprises, with offers that are frequently twice or three times the price of Juniper products for essentially the same features. Even though their name previously demanded those kinds of price tags, it’s difficult to justify the high costs today.
-
JUNOS
The JUNOS operating system is the ultimate compelling reason to buy a Juniper switch. It has two main advantages over Cisco’s offerings:
Modular design: Every operation and component in a Juniper network setup is isolated from one another. The failure of one module does not influence the remainder of the system.
Single train compatibility: All Juniper switches, routers, and other products use the same JUNOS operating system. It is designed for simple system interoperability.
-
Security
Juniper takes pride in its level of security. Juniper defines device security as having three components: physical hardware security, operating system security, and configuration-based security.
Juniper uses cutting-edge software to offer a secure user experience to meet these three requirements. Juniper’s operating system, for example, supports Terminal Access Controller Access Control System Plus (TACACS+). TACACS+ is an authentication technique for routers and switches. It is administered centrally, and authenticated users can access any router, switch, or gateway on a network.
The latest Juniper switches provide cloud-grade, high-density Ethernet switching throughout your data center, campus, and branch. To buy all of the latest Juniper switches, including the EX and QF series, visit Gear Net Technologies or Whatsapp at +971585811786.
What Are Ethernet Twisted Pair Cables? What Are Their Types?
Ethernet cable uses twisted pairs of insulated copper wires for the network’s physical layer, which is paired with the data connection layer.
Twisted pair cable wires are wrapped around one another to reduce interference from other twisted pairs in the cable. The two twisted wires help to prevent crosstalk, which can disrupt signals, as well as electromagnetic induction, which generates a voltage across a conductor moving through a magnetic field.
Twisted-pair cables, along with coaxial cables, were among the first guided transmission media. Twisted-pair cables are now employed in a variety of networking and communication applications, such as phone lines, DSL, and local area networks.
Understanding the Depths of Ethernet Twisted Pair Cables
A twisted-pair cable is simply a cable that has one or more pairs of insulated strands of copper wire twisted around one another. One wire in the pair transmits data, while the other serves as a ground reference.
These cables can be used in both bus topologies, where the cable is set out as a single line and runs through all stations, and star topologies, where each computer or terminal is connected to a central hub by a single twisted-pair cable.
Ethernet Cable Categories
There are numerous Ethernet cable types available, each with its purpose and use. As a result, if you want to learn everything there is to know about Ethernet cables, you must first grasp each cable and its application. You must select a higher-grade cable that is stronger, quicker, and better suited to your unique needs.
However, depending on your hardware, you can choose from the ethernet cabling categories listed below.
Category-3
Cat3 cable is a previous generation of cable that has a maximum frequency of 16 MHz. This cable may have 2, 3, or 4 copper pairs. Cat3 Ethernet cables are still used in two-line telephone systems and 10BASE-T networks.
Category-5
These wires are slower than modern hardware needs. As a result, you should only use this type of Cable if you have older hardware that requires outdated hardware.
Category-5e
Cat5e is one of the most popular Ethernet cable cabling types used for installations due to its ability to provide Gigabit speeds at a low cost. Cat 5e may enable rates of up to 1000 Mbps, making it suitable for small-space installations. As a result, it is commonly employed in residential settings. Cat5e is one of the most affordable cabling solutions on the market.
Category-6:
Category-6: These cables are more tightly twisted, with two or more twists per centimeter. When transmitting at 10 Gbps rates, it only supports 37-55 meters.
Category-6a:
Cat6a cabling is thicker than Cat6 cabling, making it less flexible. As a result, it is more suited for industrial situations and has a lower price point.
Category-7:
Category-7: This Ethernet cable has considerable shielding to reduce signal loss. In comparison to prior generations of cabling, it is relatively rigid.
Category-8
This cable is suited for frequencies up to 2000 MHz. CAT8 cables support 25/40GBASE-T Gigabit Ethernet, which minimizes power consumption and is intended for high-bandwidth data center applications.
This type of cable is excellent for applications when the distance between units is minimal. CAT8 cables are backward compatible with prior Ethernet cable categories.
Types of Ethernet Cables
Ethernet cables are classified into three types:
- Fiber-optic cable
- Coaxial cable
- Twisted-pair cable
Fiber-optic cabling:
Fiber optic cables are generally made up of central glass surrounded by various layers of protected materials. Fiber-optic cabling carries light rather than electronic signals, eliminating the problem of electrical interference. This makes it an excellent choice for areas with a high level of electrical interference.
This sort of network wire can send signals across longer distances. It also allows for the transmission of information in a shorter amount of time.
There are two kinds of fiber-optic cables:
- Single-mode fiber (SMF)-This form of fiber optic cable transmits data using only a single ray of light. It is used for longer-distance wiring.
- Multi-mode fiber (MMF)-This form of fiber-optic transports data by using numerous light rays. It is cheaper than SMF.
Coaxial cable
Coaxial Cable is a 10 Mbps Ethernet cable standard. These cables are made up of an inner copper wire cover with insulation and an additional layer of shielding.
It has a plastic layer between the braided metal shield and the center conductor that provides insulation. In the middle of coaxial cabling is a single copper conductor.
Twisted-pair cables:
Twisted-Pair Cabling is a type of cabling in which two wire pairs are twisted together to eliminate electromagnetic interference (EMI) from other wire pairs.
Two types of twisted pair cables are
1) Unshielded Twisted pair
2) Shielded Twisted pair
Unshielded twisted pair
A UTP cable, as the name implies, lacks internal shielding. The most popular twisted-pair cable used in Ethernet networks is the UTP cable. It is also used in older telephone systems (UTP-Cat1). UTP cables are widely used because of their inexpensive cost, ease of installation, and versatility.
Shielded twisted pair
STP cables have shielding around the conductors, commonly formed of aluminum foil, to isolate the conductors and improve the cables’ resistance to noise and signal interference. One disadvantage of STP cables is that they are more difficult to connect at termination points. STP cables are also more expensive than UTP cables. Because they avoid signal interference better than UTP cables, the extra expense may be justified
Types of Shielded Twisted Pair Cables
Foiled/Unshielded Twisted Pair (F/UTP): This type of cable has a foil shield that may be wrapped around unshielded twisted pairs. It is often used in fast Ethernet deployments.
Braided/Unshielded Twisted Pair (S/UTP) Cable: It will wrap a braided shield around unshielded twisted pairs.
Braided Shielding/Foiled Twisted Pair (S/FTP): Each twisted pair in this shield Ethernet8. cable is covered in foil.
Braided Shielding+Foil/Unshielded Twisted Pairs (SF/UTP): This cable braid has a cover that wraps around a foil wrap that encloses unshielded twisted pairs.
Foiled/Foiled Twisted Pair (F/FTP): This form of FTP cable covers all copper pairs with foil.
Unshielded/Foiled Twisted Pairs (U/FT): This cable only encases the twisted pairs in foil.

What is the Difference between Twisted Pair & Non-Twisted Pair Cables?
When selecting cables for your networking and communication applications, it is important to understand the differences between twisted pair cables and non-twisted pair cables. Both types of cables can be used for many different purposes, but the type you choose will depend on your specific needs.
In this blog post, we’ll take a closer look at the differences between these two types of cables and explain why one might be better suited for your application than the other.
Twisted Pair Cables
The twisting of the two wires together helps reduce the amount of electromagnetic interference (EMI) from external sources, such as power lines and motors. This makes them ideal for use in environments where EMI can be a problem.
Additionally, UTP cables are usually easier to install than STP cables, since they don’t require any additional shielding. They also tend to cost less than non-twisted pair cables. Finally, UTP cables typically have better transmission speed than non-twisted pair cables, which makes them suitable for data transfer applications.
Twisted pair cables are highly resistant to electromagnetic interference (EMI) and crosstalk. This makes them ideal for use in environments with heavy electrical noise, such as near factories or power lines. Additionally, twisted pair cables can transmit data at faster speeds than non-twisted cables, since the twisting of the pairs minimizes electrical noise and allows for better signal integrity.
However, the minor disadvantage of twisted pair cables is that they require a more complex installation process than non-twisted cables. The wires must be twisted together in order to provide the maximum amount of noise reduction, which adds to the cost and difficulty of installation. Additionally, the twisting of the wires can make them more prone to physical damage.
Non-Twisted Pair Cables
These cables are widely used in computer networks due to their flexibility and cost efficiency. However, they are also prone to interference from other electrical devices and do not provide as much protection from external noise sources as twisted pair cables. They come in two main types, shielded non-twisted pair (STP) and unshielded non-twisted pair (UTP).
STP cables have an extra layer of shielding around each individual wire that helps reduce any interference but can add significantly to the cost of a cable run. UTP cables lack this layer of shielding but still offer some protection from crosstalk and other forms of interference.
The main advantage of non-twisted pair cables is that they are much simpler to install than twisted pair cables. They also tend to be less expensive and easier to work with.
Unfortunately, non-twisted pair cables are more susceptible to EMI and crosstalk than twisted pair cables, making them less suitable for environments with high levels of electrical noise. Additionally, data transfer speeds tend to be slower over non-twisted cables due to their lack of signal integrity.
The Major Differences between the Two
Twisted pair and non-twisted pair cables both have their own advantages and disadvantages, so it’s important to understand the differences between them.
The major difference between twisted pair and non-twisted pair cables is the way in which they are designed. A twisted pair cable consists of two insulated copper wires that are twisted together. This twisting creates a strong electromagnetic field that can be used to reduce interference from other signals. Non-twisted pair cables, on the other hand, are made up of multiple individually insulated wires that are not twisted together.
Another difference between the two is the way in which they handle interference. Because twisted pair cables have a stronger electromagnetic field, they are better able to handle interference from other signals.
Non-twisted pair cables, on the other hand, are more prone to interference from outside signals, as there is no twisting to help reduce interference.
In addition to this, twisted pair cables also offer higher speed and longer distances for data transmission than non-twisted pair cables. This makes them ideal for applications that require long distance connections.
Finally, twisted pair cables typically cost more than non-twisted pair cables due to the extra effort required to twist the wires. However, this cost is often worth it if you need the extra protection against interference or need to transmit data over a long distance.
Which One Should You Use?
When it comes to choosing between twisted pair and non-twisted pair cables, the decision will largely depend on your application. Twisted pair cables are generally better suited for high speed and low interference data transmission, whereas non-twisted pair cables are best used for applications that require durability and are not affected by interference.
It is important to note that the right cable should be chosen based on the application and environment it will be used in. If you are uncertain which one to use, it is best to consult with a professional to make sure that you select the best solution for your needs.
Conclusion
In conclusion, the main differences between the two types of cable is how they are constructed, and how that impacts their usage. Twisted pair cables use pairs of wires that twist around each other.
This helps reduce crosstalk and any electrical interference. Non-twisted pair cables are not twisted because they are more reliable and less susceptible to interference.

How to Activate the PLR license on Cisco Security Products?
The comprehensive Cisco license reservation option is still unfamiliar to most customers. Permanent license reserve is a feature of Cisco’s smart licensing solution. A smart License requires a smart account and connection to Cisco Smart Software Management (CSSM) or Smart Software Manage (SSM on-Prem) to reactivate and report the most current license status. However, some clients have highly protected internal networks with limited internet access. So, what can they do? This is where the Cisco PLR license (Permanent License Reservation) comes into play.
What is the Cisco PLR License?
Cisco PLR licensing is a long-term solution for a highly secure network design with minimal outward connections. Using a reservation code issued by Cisco partners, you can register all product instances with exclusive features indefinitely and permanently (no renewal required). This solution is primarily available for Cisco NXOS, IOS XE/XR-based devices, and Cisco Secure product lines.
Furthermore, because most consumers are uncomfortable with Cisco smart licensing methods and find all smart accounts and virtual accounts notions complicated, PLR licenses are a straightforward solution you can use on many different devices.
Besides, you cannot use Smart Licensing if there is no path to the Internet for the system. In that case, activating Cisco PLR License is your only option.
Additionally, it may eliminate all issues regarding Cisco Essential, Advantage, and Premier Licenses, all of which have different features and expiration dates, by offering a single authorization number that can permanently enable all premium capabilities.
How to apply for a Cisco PLR License?
Some basic CLI commands on most Cisco IOS/NXOS devices, such as Cisco Catalyst switches and Cisco Nexus switches, can produce a reservation code for you. You’ll receive a unique permission number after sending the code to the sales experts. All functionalities would be permanently activated by inputting the code in the CLI.
Cisco PLR licensing is also supported by Cisco security solutions such as Cisco Identity Service Engine, Cisco Secure Firewall Management Center, Cisco Secure Firewalls, and Cisco Firewall Threat Defiance. The GUI interface provides access to this feature.
PLR License Activation on Cisco FDM
When you only have one firewall to manage, you can use Firepower Device Manager across the network. It’s a web-based database manager that operates natively on your Firepower with FTD’s box.
Workflows, illustrations, and default setup settings are all included. Cisco Device Manager comes standard with the Cisco Firepower Firewall with FTD. The FDM is a consolidated platform for applying and managing Firepower licenses.
You can use Cisco smart licenses to register all Cisco Firepower product instances. The cloud-based Cisco Smart Licensing solution allows you to automate time-consuming licensing activities.
You can check the status of your license and software usage patterns with this service. Three main functions are simplified with Smart Licensing. This new licensing method necessitates a direct or proxy Internet connection to the Cisco Smart Software Management (CSSM) website.
Although a connection to the Internet is not an alternative in highly protected areas, the Cisco PLR License allows you to install an authorization code that permanently activates all premium features on your device.
The FDM does not require any licensing. It can, however, be utilized for Firepower with the registration of FTD product instances. To activate your Firepower with FTD with a Cisco FDM PLR license, follow the procedures below:
- Turn on the device and connect via the Console Port.
- Accept the EULA and continue the procedure by entering your IP address and GW.
- The device will ask you if you wish to administer the device locally at the end of the wizard: You must select yes.
- Open a web browser and type in the IP address that you previously assigned to the device.
- You can continue the configuration procedure after connecting to the device through the Web interface and setting the Output interface IP and NTP Server.
- The procedure will ask you whether you want to activate the 90-day evaluation period without Registration or Register the device with Cisco Smart Software Manager in the last stage. You should choose a 90-day evaluation and complete it.
- When the prompt appears, choose solitary device and tap Got It. Then, on the left side of the screen, select the Smart License tab.
- A drop-down menu will appear on the right side of the screen on the Smart License page. To install the Cisco FDM PLR license, press Switch to Universal PLR.
- You now have access to the Request Code. Send this code to the supplier so that they can give you a Cisco FDM PLR license.
PLR License Activation on Cisco ISE
Using a Cisco ISE PLR license to enable all features on the Cisco Identity Service Engine platform is a straightforward process. In essence, Cisco’s permanent license reserve is a safe and dependable licensing solution for secure environments where no inbound or outgoing connections are permitted.
An authorization number issued by Cisco can be used to activate a Cisco PLR license. Customers should produce a request code from the Cisco ISE web interface and share it with sales representatives. After that, Cisco will supply you with an authorization code. Then you can register your device by following the instructions below:
Enter Setup on the CLI after finishing the Cisco ISE first deployment to begin ISE basic configuration. After that, you can use the administration IP to access the Web interface.
- Use the new username and password to log in to the device.
- Open the Hamburger menu on the ISE platform to activate the license reservation option.
- Choose the Licensing option from the Administration tab.
- Then click the Generate code button and choose PLR.
- Copy the generated code and send it to Cisco’s sales team to acquire the permission code.
- Then, in the box, type the code and click Enable.
- Your device will be fully registered and ready to use after completing these procedures.
How to Apply Permanent Licenses in Networks without Internet Access (Air-Gapped Networks)
An air-gapped network is a type of network that does not have access to the Internet. Such networks are built for high-end security services where you cannot tolerate external attacks or intrusions. Since there is no path for the Internet, it is impossible to register your devices through Cisco Smart Software Manager. In this case, you can switch to Permanent License Reservation (PLR) mode to get the license for your device.
Things to Keep in Mind to Use PLR Mode Before Activating PLR License
- All features that require internet access, such as file policies, URL lookups, etc. will not work.
- Cisco cannot collect data even if you enable Web Analytics and Cisco Success Network.
- You are required to upload all the updates manually to the Geolocation Database, Intrusion Rules, and Vulnerability Database (VDB). In other words, you can use a flashdrive for updates download, carry the drive to your secured building, and manually upload the updates in the devices.
- You need to verify that your smart account provides a universal license and you have purchased the required Universal License.
- For those in evaluation mode, they cannot switch back to evaluation mode if they switch to PLR mode.
- In case you have a High Availability configured (HA) device, you need to complete the process separately for both devices in the HA group.
Steps to Switch to PLR Mode and Apply License to Your System
Step 1: Go to Device, then select View Configuration in the Smart License summary.
Step 2: If the device has been registered using Smart Licensing, choose “Unregister Device” from the settings drop-down list.
- Confirm the unregistration and wait for the task to complete before taking any further steps.
Step 3: Select “Switch to Universal PLR” from the settings to transition to Universal Permanent License Reservation (PLR) mode.
- Once you read the warning, click “Yes” to confirm your switching process.
- The system will convert to PLR mode and initiate the PLR registration process.
Step 4: Complete PLR Registration:
- Upon opening the Universal Permanent License Reservation dialog box, save the request code displayed in the first step in a text file by clicking on “Save As TXT” option. You can also print it or simply copy it to the clipboard using CTRL + C.
- If you previously exited the process after switching modes, you can resume by clicking “Continue Reservation” on the Licensing page.
- Log into CSSM Account: Navigate to Smart Software Licensing > Inventory, then click on the “Licenses” tab.
- Click License Reservation button to initiate the reservation process by following the instructions in the wizard.
- Enter the license request code or upload the saved txt file. Click Next.
- The products details will be displayed in front of you for the system you want to license, along with a bulleted list of available licenses for the device. For a locally managed FTD device, select the Universal License and click Next.
- Once you check that you have the correct license required, click Generate Authorization code. The code will be generated in the following format: XXXXXX-XXXXXX-XXXXXX-XXXXXX-XXXXXX-XXXX
- [Note: In the above format, X is an alphanumeric character. In case authorization code is an XML file, it means you have specific license instead of universal license and you cannot use it on the system. In such a case, please Cancel the PLR Registration to ensure that you release the reserved licenses in your CSSM account and work with a Cisco representative to switch from Smart Account to PLR.]
- Once you see the authorization code, choose “Download as File” or “Copy to Clipboard” to save the code and click Close to get out of the wizard.
- Once you get back to the FDM, enter the authorization code by pasting or uploading the file. Click Register to initiate the registration.
- To check the status of registration, refresh the Licensing page.
Step 5: Enable option features that you need.
- Note that the Universal license registers the device for the Base license only. So, you can click Enable for each specific feature you need.
Steps to Cancel PLR Registration
Step 1: Click “Device” and navigate to “View Configuration“.
Step 2: Select “Cancel PLR” from the settings to begin the cancellation process.
Step 3: Choose an option based on your scenario. Based on the scenario you have, select the appropriate option:
- “I have a license in CSSM“: If you have licenses reserved in CSSM and obtained an authorization code.
- “I do not have a license in CSSM“: If you haven’t completed the CSSM wizard to obtain an authorization code.
Step 4: Obtain release code (If CSSM License Exists). If you selected “I have a license in CSSM,” paste the authorization code into the dialog box of cancellation and click “Generate Release Code.”
- Once a code appears in the Release License Code field, click Save As TXT file or Print it. Or, copy the release code.
- In CSSM, locate the device in Smart Software Licensing > Inventory, click Action > Remove, and enter the release code.
- Wait for CSSM to confirm the successful removal of the product.
Step 5: Click “OK” to finalize the cancellation process.
The system reverts to Smart License mode, but note that the device is now unregistered, and restarting evaluation mode is not possible.
To use the device, either register it using a Smart License or switch back to PLR mode and register again.
Wrapping Up
Remember that PLR licenses are node-locked, meaning they cannot be transferred between platforms. Each authorization number you’ve got is unique to your current product, and no one can use it without your permission.

How Do You Set Up IP Addresses on a Cisco Router?
Router configuration and setting up IP addresses is a routine task for network administrators and network engineers. Routers available for enterprises are a lot different from routers available for use at home. Business-grade routers are assigned static IP addresses, unlike home-use routers which are assigned dynamic IP addresses.
It is essential to know how to configure and assign IP addresses on a Cisco because this is the task that is done even before installing a router in the network. You need to assign an IP address before doing anything with a router. Fortunately, configuring a Cisco router with an IP address is not a complicated task. Since this guide is for beginners, we will discuss the configuration process of routers in detail.
4 Steps to Configure a Cisco Router with IP Address
There are typically four steps to follow when you need to configure a router. These steps are as follows:
- Verify the router’s current interface configuration
- Select the interface you need to assign an IP address to
- Assign the IP address to the interface
- Enable the interface on your router
Now, let’s learn how to assign an IP address to a Cisco router in detail and all those things you will need during router configuration.
How to Find and Display Interfaces on a Cisco Router
Before assigning an IP address to a router, you will first need to know the current configuration of that router. Generally, Cisco routers come with interfaces that are shut down out of the box. Hence, you need to check its interfaces, especially if a router is being re-used.
To display interfaces in a Cisco router:
- Go to the console window
- Run the “show IP interface brief” command
This command will help you learn about:
- Each interface and its name
- The current IP address for each interface
- If each interface is up or down on the Layer 1 level
- If each interface is up or down on the Layer 2 level
The Status and Protocol columns will show one of the three status messages, namely, up, down, or administratively down.
Each message indicates the status of the associated interface.
- The “Up” message means that the interface is working correctly.
- The “Administratively Down” message means that the interface has been disabled by the network admin by configuration.
- The “Down” message means the interface is not working for other reasons, such as the network cable is not plugged into the network port.
Cisco routers that come out of the box often have an “Administratively down” status for each interface. This is different for Cisco switches as they come already configured right out of the box and can be implemented directly in many cases.
However, using a non-configured or improperly configured router can make a network not functional and can send data from the network into a black hole.
How is Status different from Protocol in router configuration?
When using the command to show interface status, the router will display all the information about each interface on the console. That information will include the link state which is labeled as Status and Protocol.
Status and Protocol, both labels represent different layers on the OSI networking model. The Status column refers to Layer 1 or the physical connection layer, while the Protocol column is for Layer 2.
Hence, the Status shows if a cable is physically connected or if the physical hardware for that interface is working fine. On the other hand, Protocol explains if that interface is receiving signals that it can interpret and identify.
This is why it is crucial to understand the difference between Layer 1 and Layer 2 and their operational status before you configure Cisco routers and diagnose issues in the future.
How to Select an Interface for Assigning IP Address on a Cisco Router
Once you verify the state of all interfaces on a Cisco router, you will need to select the interface in the console.
When you run the “show IP interface brief” command, you need to pay attention to all the interfaces displayed on the console. This will help you avoid plugging the Ethernet cable in the wrong port.
To select an interface, enter the global configuration mode in the router. Now, use the “configure terminal” command to enter configuration mode. Then, use the “interface” command to select that interface. For additional help, you can also add a question mark after the interface command.
Example: interface g0/0
In this example, the network admin has selected the interface which is a gigabit Ethernet port on the router. Depending on your router, you may see differently labeled interfaces.
How to Assign an IP address to a Cisco Router
After listing each interface, entering global configuration mode, and selecting the interface, you can finally assign an IP address to that interface. The assignment of an IP address to the interface is quite simple. All you need is to just use the “IP address” command followed by the IP address for that interface port and its subnet.
For instance: IP address 192.168.1.1 255.255.255.0
If there is any error, you will get the message. If everything is done correctly, you will not get any confirmation message. It is simply done.
After this, you can again run the “show IP interface brief” command to see the IP address that you assign to your interface.
How to Enable an Interface on a Cisco Router
To activate the interface, you will need to enable the interface on the router. First, enter the “show run” command to see the router’s status and configuration and check the current information of each interface. You can use the space button to jump and see all configuration information. After the interface status is verified, select the interface and use the “no shutdown” command to enable the interface.
If everything is fine, you will get three messages. The first message will show that the interface is down, and then the next two messages should convey that the Status and Protocol are up now. You can also see LEDs blinking next to the physical interface port that is just configured on the router.

How to Setup a Virtual Chassis on a Juniper EX Series?
Juniper EX-series switches is scalable. But, people don’t take advantage of this feature frequently. They use these Juniper switches like others. If you want to take advantage of the scalability features of the Juniper EX series, you should configure a Virtual Chassis. Not one or two, but this configuration is possible with all the Juniper Ex-series switches. The only difference is the number of member switches they can include.
For example, the EX3300 virtual chassis includes up to 6 member switches, the EX2200 and EX2200-C virtual chassis include up to 4 member switches, the EX3300 virtual chassis includes up to 10 member switches, and EX4200, EX4300, EX4500, EX4550, and EX4600 virtual chassis include up to 10 member switches. Connecting the member switches is possible using dedicated Virtual Chassis Ports or VCPs. Here, you do not have to configure the interface for the dedicated VCPs.
Why should you set up a Virtual Chassis configuration?
Virtual Chassis configuration allows accommodation of the networking needs of a growing office. Though there is a default configuration of a two-member Virtual Chassis, additional configuration is important. The Virtual Chassis configuration provides more access ports than what a single provides as well as high availability through redundancy.
We will take an example of a Virtual Chassis configuration composed of two EX4200 switches. Here, one of the switches has an uplink module with ports, configured to connect to a distribution switch or customer edge (CE) router or configured as Virtual Chassis Ports or VCPs to interconnect with a member switch that is located too far for the dedicated VCP cabling.
When you interconnect the switches with the dedicated VCPs and power on the switches, the VCPs become operational. The software assigns the primary role priorities and member IDs as well as elects a primary based on several criteria. One of the major criteria is how long a member switch has belonged to the Virtual Chassis configuration. It’s recommended to start by powering only one member switch. This member switch will be the one that you want to function as the primary.
The Virtual Chassis configuration can provide networking access for 50 onsite workers, sitting within the range of a single wiring closet. If your office grows and more members join your organization, you can add more switches and meet the increased need for access ports. At any cost, the operations and performance of your office will not get hampered.
How to Setup a Virtual Chassis on a Juniper EX Series
In this post, we will discuss setting up a Virtual Chassis configuration on a Juniper EX series by using the J-Web Interface.
Virtual Chassis configuration by using the J-Web Interface
- On the interface, select Configure and then Virtual Chassis.
- On the next page, the properties that you can configure are displayed. This is the Virtual Configuration page that is divided into two sections.
- In the first section, the page displays the Virtual Chassis member configuration. It includes a list of member switches, their member IDs, and the primary-role priority.
- In the second section, the page displays the operational status of the Virtual Chassis configuration, member details, and the dedicated and configured VCPs.
- Enter the asked details into the page. The details include the following:
- Member ID– You should specify the identifier for the member switch.
- Priority– You should specify the primary-role priority assigned to the member
- Disable Management VLAN– You can remove the Ethernet port from being part of the virtual management Ethernet (VME) interface if you want to reserve an individual member’s management Ethernet port.
- Refresh– You should refresh the operational status of Virtual Chassis members.
- On the next page, you should click one of the following options for the given reasons:
- Add– If you want a member’s configuration to the Virtual Chassis configuration
- Edit– If you want to modify an existing member’s configuration
- Delete– If you want to delete the configuration of a member
The last two steps will define the configuration process based on different models of the Juniper EX-series switches.
- Select the member in the Virtual Chassis members list and select the Action button and then Set Uplink Port as VCP to configure uplink ports on EX2200, EX2200-C, and EX3300 switches and uplink module ports on EX4200, EX4300, EX4500 and EX4600 switches as VCPs. You should select the port from the list.
To configure a VCP on EX4550 switches, you should select the member in the Virtual Chassis members list and select Action followed by Set Port as VCP.
- You can remove the VCP configuration as well. If you want to remove the VCP configuration from the uplink ports on EX2200, EX2200-C, and EX3300 switches and uplink module ports on EX4200, EX4300, EX4500, and EX4600 switches, you should select the member in the Virtual Chassis members list and select Action and then Delete Uplink Port a VCP.
To remove the VCP configuration from the port of a member on EX4550 switches, you should select the member in the Virtual Chassis members list and select Action followed by Delete Port as VCP.
Conclusion
Though the steps to set up Virtual Chassis on a Juniper EX-series are known, people face lots of problems when implementing them. They get stuck and face further problems. So, we recommend taking help from professionals. They know the configuration process in the right way.

How Do Routers Use IP Address to Transfer Data?
This subject is frequently discussed in the industry by IT experts and by students and beginners attempting to understand how routers and data transfer work. If you’ve been looking for the same answer for a while, we’ve got you covered! For more information about routers, packets, and how data is sent from routers to your systems, keep reading.
Data packets moving to and from a computer to a host across the Internet depend heavily on network routers. Routers act as the connecting device between the computers in a network and the source of the Internet connection. Data packets are used by computers to communicate with one another across network connections, and the router’s responsibility is to ensure that these packets reach their intended destinations.
What is a packet?
A packet is a compact data unit that is transferred through a network from one device to another. Larger files are divided into smaller ones by packets to minimize the amount of work required if any data is misplaced while being transferred from one system to another.
Each packet has a checksum that can be used to identify whether it has bad data or has been corrupted, in which case it must be sent again until it is accurate. Any errors would destroy the entire file if it were transferred intact.
Additionally, packets are useful when a network becomes overloaded and the router is forced to turn down packets for later transfer.
What is a router? How does it work?
The device that controls traffic and manages packet transfers between networks is a router. Routers use packets, which can carry a variety of data types, including files, messages, and straightforward broadcasts like online activities.
The data packets are divided into layers or sections, and one of these layers or sections contains the destination IP (Internet protocol) address in addition to another sender, data type, and size identifying information. This layer is read by the router, which then prioritizes the data and selects the most efficient path for each transfer.
In essence, routers choose the destination for a data packet before forwarding it to the following network point.
According to Cisco, routers connect networks and are frequently confused with other gear called switches that establish networks. Most home and small office networks use routers, which are essentially hybrid devices that combine the functions of a router, network switch, and Wi-Fi adaptor into a single piece of hardware. The router just manages the data transmission and path selection.
Switch vs. Router: What is the difference between them?
Switches allow resource sharing by linking all of the devices in a small company network, including PCs, printers, and servers. Because of the switch, these connected devices can share information and communicate with one another regardless of where they are in the building or on campus. A small business network cannot be built without switches to connect devices.
Similar to how a switch connects various devices to build a network, router links many switches and the networks they each establish to create a much bigger network. These networks could be at a single site or spread across several areas.
You’ll need one or more routers to set up a small business network. The router, in addition to linking various networks, allows networked devices and many people to access the Internet.
How Is Router Path Determined?
One of the router’s responsibilities is to ensure that an incoming data packet reaches the computer that requested it. The router discovers and acts as the gatekeeper for all computers and devices connected to the network. If the packet comes from an external host, the router directs it from the modem to the computer that is supposed to receive the data. Additionally, the router is in charge of sending outgoing packet requests to the modem.
How Are Packets Transferred from Routers to Different IP addresses?
The router will detect whether the packet is meant for any of the networks to which it is linked by comparing the IP address to the router’s known network addresses. If it detects a match, the router will utilize the interface for that network to determine the MAC (media access control) address associated with the IP address, then transmit it out via a switch.
If the router is also a switch, as most residential routers are, it will automatically determine which interface that MAC address is on and send it out to that interface. Otherwise, it forwards it to the switch to handle.
If the router discovers that the packet is not intended for one of its own networks, it will consult its route table.
A router in a home network is most often connected to only two networks: the home network and the ISP’s edge network. In such a situation, almost any outgoing packet will cause the router to just transmit the packet to its default gateway using the same mechanism, and then the ISP’s router will utilize the same routing determination.
In routers linked to more than two networks, the packet may match a non-default route, in which case the router will follow that route and send it through that interface to the next step.
What Are Routing Tables?
Routers store routing information in routing tables. The IP addresses of the hosts and routers on the networks to which the router is linked are stored in these tables. These networks are also referenced in the tables. When a router receives a packet, it checks its routing database to see if the destination address is listed in the header. If the destination address is not found in the table, the router passes the packet to another router in its routing table.

Why Are Security Cameras at Risk of Hacking?
You install security cameras to secure your premises. With security cameras, you get a third eye to keep a check on your property from anywhere you want. You don’t have to be physically present to know what happened and who was behind it. You can remotely check the videos and decide on the next step. But, the thing is that security cameras need security for themselves to secure your premises.
Did you understand the last statement? We will explain again but in a different way.
Security cameras are at risk of hacking. Yes, you read it right. Hackers find loopholes and are ready to hack security cameras for their benefit. They get a lot of information by hacking your security cameras.
How are security cameras at risk?
Hackers don’t hack security cameras. They find different ways to do that. And unfortunately, you give this option to the hackers and suffer the consequences.
To view the activities at your property from remote locations, you connect your security cameras to various devices like mobiles, PC, or laptops through the internet. Through this connection, you check the live as well as recorded footage of the security cameras. This is where the hackers attack indirectly.
Hackers reach the security cameras through the software you use on the connected devices. They check details and manipulate things in their favor. Sometimes, they divert the recording to their devices without you knowing about this. In other words, two or more people access the recordings of the security cameras.
Other than this, you allow hackers to hack your security cameras by using unlicensed pieces of equipment. You don’t follow the rules and regulations to install security cameras. Most importantly, you don’t use security software to protect your systems and cameras. Because of this easy and convenient access, the hackers guess the passwords and attack.
What should you do to prevent the hacking of your security cameras?
Buy cameras from a trusted source
We already said that poor equipment makes hacking easier for hackers. As security cameras are the primary device, you should buy them from a trusted source. It’s said that the efficiency of the cameras increases when they are manufactured by a reputable brand and bought from a trustworthy supplier.
Along with security cameras, other hardware components should be of high quality as cheap quality will make them vulnerable to hackers. Also, you should take care of the software design of the security cameras. The software design should be of high quality to prevent widespread vulnerabilities.
Opt for 2-factor authentication
Hacking becomes easier for hackers when they guess the passwords and find that there are roadblocks ahead. They just have to enter the password to access the software and get the important details.
To prevent unwanted access to computer and network devices, you should have unique and strong passwords for all the devices connected through the internet. We know it’s difficult because strong passwords are not easy to remember. And you very well know that using the wrong passwords several times can block your access.
You can get rid of this memory problem by using a reputable software-based password manager. This application keeps passwords secure and prevents them from being forgotten or lost. But still, you should change the passwords every three months to increase the security of your device and data.
Regarding the 2-factor authentication system, it’s the second line of defense that requires a separate device to allow login into the account. Whether you are logging into your connected devices or software to check the videos, the authentication link or code will go to another system as well. The login will happen only if the person receiving the link or code confirms. This is done to authenticate the identity of the user.
As an account gets logged in two steps, it’s known as a 2-factor authentication system. This system adds an extra layer of protection.
Use a secured Wi-Fi access
Whether it’s your home or office, you should use a secured Wi-Fi network to connect the security cameras. If the Wi-Fi network is secure, you will avoid the risk of being hacked.
For secured Wi-Fi access, you should get a connection from a reliable service provider. You should avoid local connections and opt for brand connections. Make sure the Wi-Fi connection you choose is used by others as well. You shouldn’t be a single user of that particular network provider.
Other than this, you should have quality Wi-Fi routers and internet modems and update them regularly. No matter what, you shouldn’t use old and outdated devices for Wi-Fi networks as they are vulnerable to hacking.
Check firmware and software updates
The firmware and software used by you to run the security cameras and check the videos captured by them should be updated. Though it’s the responsibility of the security camera vendor, you should keep your eyes on them as well.
In every situation, you should use the latest released firmware and software on your systems and for your security cameras. Also, you should update them regularly as it’s not a one-time process. Updating will prevent hackers from using critical vulnerabilities.
If you are looking for security camera installation in Dubai, come to Gear Net Technologies. We offer advanced technology security camera installation along with quality products to keep your security system within your premises safe and protected from vulnerabilities.

Why are the wires within an Ethernet cable twisted?
“Why is Ethernet wire twisted inside?” is a subject that IT professionals and cabling experts are frequently asked. This riddle is around the operation of Ethernet cable and why it is referred to as balanced twisted pair. Let us unravel this riddle and discover the truth!
How do the twisted wires work?
The twists’ principal function is to reduce internal electrical interference. In effect, Ethernet cable has its own “shielding” built in. You may believe that unshielded Ethernet cable has no shielding and that protected Ethernet cable has shielding. This is just partly true. While shielded Ethernet cable, such as F/UTP has an overall foil shield, the cable cannot function without the “built-in” shielding of twisted pairs.
The purpose of the external, general foil shield is to keep outside electricity (magnetic fields or radio waves) from getting into your cable.
Every wire conductor produces an uneven electromagnetic field. As a result, one conductor may interfere with another. Given that gigabit Ethernet uses all eight conductors, this would be a terrible disaster if all the conductors began “talking” to each other. Cross-talk occurs when electrons are passed back and forth between conductors.
There will be a magnetic field encompassing every extension cable or anything that passes electrons through it to some degree. The magnetic field becomes smaller as the voltage decreases. The voltage in the Ethernet cable is relatively low, but it is still present, and the twists in the conductor pairs protect the cable from itself.
Each twist reverses the polarity of the conductors, canceling out disparities in their unique electromagnetic fields. As a result, electromagnetic equilibrium is achieved, which is why Ethernet cable is referred to as balanced twisted pair. We have achieved harmony. The couple is “quieter,” similar to a library. We can now converse with each other and genuinely understand each other.
What are the Reasons for Twisted Wires?
The Reduction of Noise
No engineer would tamper with equipment unless there was a benefit to doing so. The colorful wires are not twisted to make the conductor look odd; they are twisted to reduce unwanted noise signals.
Previously, telephone wires were not as elaborately or widely twisted as they are now. The pair of wires carrying or receiving telephonic signals would be twisted or their places on each pole would be switched. These poles were spaced at equal intervals and piled for several kilometers. The pole, now a relic from a brilliant era of scientific discoveries and advancements that saw the birth of what is now called “premodern” or even “modern” technology, can still be seen in rural areas.
The impulses sent over the two cables were of similar magnitude but polarity. As a result, if one wire carries a voltage +A signal, the wire parallel to it will carry a voltage -A signal. These are known as differential signals because the output of a receiver when they are received is the arithmetic difference of these signals. To generate 2A, the receiver subtracts A and -A. But why is this so clever?
Only in an ideal world would the receiver receive both signals A and -A without any noise. The environment will inevitably introduce noise into the cables, causing the signals to be corrupted. Noise signals, on the other hand, are injected without any polarity reversal: the source of noise induces a voltage component in both lines, say, +N, rather than +N and -N. As a result, the distorted signals received by the receiver are (A+N) and (N-A). However, because it subtracts both inputs, the resulting output is completely noise-free, as (A+N) – (N-A) = 2A.
However, it is based on a fallacy. It is based on the assumption that the amplitude of the noise created in the two parallel lines is equal. This is undoubtedly false, because the source may not be equidistant from the two cables. As a result, one wire would be subjected to more noise than the other.
One solution is to expose the other wire to additional noise, so making the two components equal. The magnitude of noise created in the two wires would be the same if they were regularly exposed to the source of noise turn after turn. This may be accomplished by twisting or swapping the wires!
Electromagnetic Interference (EMI)
Wires are no longer thick and taut between tall poles; instead, they are incredibly thin and commonly found taut or spreading between small, weirdly shaped boxes a century later. And, yeah, boxes and wires are connecting them all over the place.
The issue presented by so many closely spaced wires is that noise in a wire is now created not only by the environment but also by other wires in its vicinity. Electrons in motion, like those that make up a current in a conductor, emit electromagnetic waves. Electrons in the wire next to it can be disturbed by electromagnetic waves produced by one wire. Because EM waves are made up of oscillating or changing magnetic fields, an EM wave passing through a wire can generate a current in it. This is known as cross-talk, and the noise is known as electromagnetic interference (EMI).
Extensive braiding eliminates noise in two ways: first, as previously stated, equal exposure to the source ensures that most of the noise is canceled when the signals are subtracted by the receiver; and second, at each twist, the magnetic field produced by the wire changes its polarity, such that the currents induced are opposite in polarity, which eventually negate each other to produce effectively noise-free signals. Effectively, but not entirely!

What is the Purpose of Fiber Optic Cable?
The fight between fiber optical and copper cables has always been intense. But, in the current scenario, things are a bit sorted as most people have inclined to fiber optic cables. You will find only a small number of people using copper cables. And the main reason for this is that they are not much aware of the fiber optic cables.
In this post, we will discuss the purpose of fiber optic cable along with its other important details and specifications.
Fiber optic cable is based on fiber optics, a technology that transmits information as light pulses along a glass or plastic fiber. It contains a varying number of glass fibers, ranging from a few to a couple hundred. There is another glass layer called cladding, surrounding the glass fiber core. The cladding is protected by a buffer tube layer and a jacket layer acts as the final protective layer. The final or protective layer is for the individual strand.
How does fiber optic cable work?
The data is transmitted in the form of light particles or photons from fiber optics pulses through a fiber optic cable. Every glass fiber and cladding in the cable bends the incoming light at a certain angle as they have a different refractive index.
Light signals sent through the fiber optic cable reflect off the core and cladding in a series of zig-zag bounces. This process is called total internal reflection. As the glass layers are denser, the light signals don’t travel at the speed of light. The traveling speed of the light signals is about 30% slower than the speed of light.
The fiber optic cable supports up to 10Gbps signals. The thing is that the cost of cable increases if its bandwidth increases.
Is there a way to boost the signal journey?
Yes, there is a way to boost the signal throughout its journey using repeaters at distant intervals. Used for fiber optics transmission, the repeaters regenerate the optical signal by converting it to an electrical signal. Then, the repeaters process the electrical signal and retransmit the optical signal.
What are the types of fiber optic cables?
Single-mode fiber
Due to the smaller diameter of the glass fiber core, the single-mode fiber is used for longer distances. It’s because a smaller diameter lessens the possibility of attenuation. The attenuation is defined as a reduction in signal strength.
The single-mode fiber has a smaller opening as well. This opening isolates the light into a single beam, which offers a more direct route and enables the signal to travel a longer distance.
Other than this, the single-mode fiber has considerably higher bandwidth, so it’s expensive. Another reason for its high cost is that it requires precise calculations to produce the laser light in a smaller opening. And the laser is the light source used for single-mode fiber.
Multimode fiber
Due to the larger core opening, the multimode fiber is used for shorter distances. The core opening of the multimode fiber enables light signals to bounce and reflect more along the way. Also, the diameter is large, which permits multiple light pulses to be sent through the cable at one time. This results in more data transmission.
Unlike single-mode fiber, the multimode fiber uses a LED to create the light pulse. People don’t consider multimode fiber cable because there is more possibility for signal loss, reduction, and interference.
What’s the purpose of fiber optic cables?
The advantages of fiber optic cables of supporting higher bandwidth capacities, further light traveling without needing as much of a signal boost, being less susceptible to interference, being submerged in water, being stronger, thinner, and lighter than copper cables, and not requiring frequent maintenance or replacement make them highly purposeful. The cables can be used for different reasons and in different industries.
Computer networking and broadcasting
The fiber optic cable’s ability to transmit data and provide high bandwidth makes it an important element in computer networking. This is a very common use case of cable. For the same reasons, cable is frequently used in broadcasting and electronics, providing better connections and performance.
Internet and cable television
Both internet and cable television require long-distance connections. Sometimes, the connection requirement is between two computer networks in different locations. To establish this connection seamlessly, the fiber optic cable is used. No other cables can provide such strong data transmission over a long distance.
Undersea environments
As already mentioned, the advantage of fiber optic cable is that it can be submerged in water. Based on this, the cable can be used in undersea environments and other at-risk situations. The best thing is that fiber optic cable doesn’t require frequent replacement even if it is submerged in water.
Military and space
Other than the communication and signal transfer, the fiber optic cable provides temperature sensing. This is what makes the cable suitable for military and space industries. Other reasons that make fiber optic cable suitable for military and space industries is its lightweight and small size.
Medical
In the medical industry, fiber optic cable is used in a variety of medical instruments to provide precise illumination. As the cable enables biomedical sensors, it helps in minimally invasive medical procedures. Other than this, you will find the use of cable in various tests like MRI scans because it is not subject to electromagnetic interference.
The purpose of a fiber optic cable is very strong. It simplifies the work in different industries. So, choose it over a copper cable.
