Cisco Nexus Vs. Catalyst Switches: What’s the Difference?
Cisco offers a wide range of modular and fixed-configuration switches to help companies find the best networking solution for their needs. These switches let you keep up with your organization’s ever-changing dynamics.
The Cisco Nexus and Catalyst switches are the most popular switches available today. While Nexus switches are a versatile and feature-rich option that is simple to install and use, Catalyst switches provide superior control over throughput traffic.
Moreover, both have advantages and disadvantages. So, here we will help you understand the distinctions between the two switches.
Cisco Nexus Switches
The Cisco Nexus switches enable access to storage and network resources on all servers. These switches aided in removing the requirement for computing networks or parallel storage.
The Nexus switches now run on NX-OS, which is a Linux-based operating system. They work effectively as a data center platform that includes modular software packages.
These switches should be employed in Cisco-dominated environments with deep pockets. They could be suitable for combining Ethernet, FCoE, and fiber channels in a single chassis.
Features of Cisco Nexus Switches
This switch line is simple to program and is a great place to start if you’re interested in SDN but haven’t gotten there yet. To begin, you’ll need both a username and a password to log into the system.
Supporting DevOps solutions, such as Cisco Data Center Network Manager (DCNM), allow you to automate quickly and effectively. In the Nexus product line, you’ll find a variety of solutions ideal for practically any setup.
You can go about it in any method that suits your needs, whether it’s stacking switches or employing modular switches. Nexus switches also operate well in a multi-tenant network environment, which is ideal for cloud services, thanks to its support for VXLAN.
The series is stable, and it allows you to upgrade individual Nexus switches while keeping the server up and running.
The connection is adaptable. So even if the onsite is offline, the network maintains quality. Its overall performance is excellent, and its administration is straightforward. However, handling Nexus switches in their operations is a challenging task.
ROI of Cisco Nexus Switches
When it comes to the Return on Investment component, the Nexus purchase grants access to thousands of servers, allowing a large number of Virtual Machines to be run on a single port.
As a result, the Nexus switches provide an excellent return on investment. The subscription and licensing fees, on the other hand, are a touch too much. However, in the long run, this may be made reasonably affordable. Alternative hardware options can give you the peace of mind that you’re staying within your company’s budget.
Cisco Catalyst Switches
Wireless controllers, network switches, and wireless access points are available on Cisco Catalyst switches. When it comes to switches, IOS is the operating system of choice. In order to get started, you’ll need either a single passcode or a combination of password and username information. These switches are well-suited for enterprise networks that demand a large number of network devices and where good uptime is critical.
Features of Cisco Catalyst Switches
Catalyst switches are mainly aimed for usage in the core/distribution layers of university networks. These switches are not suitable for small businesses with a few machines, particularly where network interruptions have no bearing on the options.
Their capacity to control loops is unequaled, Syslog data is easy to access, and level-based filtering is excellent. Early defect troubleshooting can also benefit from detailed SNMP traps. Furthermore, the unit’s ability to perform both routing and switching is ideal. Routing is integrated with high-speed port density on the larger Catalyst switches.
You have access to several resources to learn more about the product or to assess any issues. The most valuable and intuitive feature is the UI. The Catalyst switches’ configuration is also rapid, simple, and secure. The monitoring system is reliable, the solution is scalable, and the customer service is responsive.
Cisco is a well-known technology company, and users favor pre-owned equipment because of its durability and dependability.
ROI of Cisco Catalyst Switches
When it comes to ROI (Return on Investment), Cisco Catalyst switches typically last longer, resulting in a higher ROI by avoiding the need to replace them before they are decommissioned. As a result, the unit is substantially more reliable, resulting in a lower TCO (Total Cost of Ownership).
Their subscription-based license adds to the expenditures, making self-sparing support strategies more difficult. The solution is most likely the most expensive. Users who want the best, on the other hand, are willing to pay a premium. Although the equipment may be worth the money, it is still more expensive than certain high-performance and dependable alternatives.
Cisco Catalyst and Cisco Nexus: What’s the Difference?
- The Catalyst only has eight ports; however, the Nexus allows you to combine ports to make a 16-port ether channel.
- The features in Catalyst are enabled by default, whereas every feature in the Nexus must be turned on individually.
- In Catalyst, we can configure multiple interfaces; however, in Nexus OS, there is no range command to configure multiple interfaces.
- In Catalyst Switches, Wildcard Mask is used, whereas, in Nexus, Subnet Mask is used in the ACL to match the network/host.
- In Catalyst, the command writes memory can be used to store configuration, whereas, in Nexus, the command copy running-config startup-config can be used to save the configuration.
- FCoE is not supported by Catalyst; however, it is supported by Nexus.
- User mode is supported by Catalyst but not supported by Nexus.
To sum it up
Nexus switches are a range of Data Center-specific devices, whereas Catalyst switches are a family of enterprise-grade networking equipment.
