DS-3E2552-HI-48T4F
48 GE RJ45, 4 GE SFP, Smart L2+ Switch
- DS-3E2500-HI series supports the combination of “Ethernet port + optical port” to meet networking requirements of various scenarios, which is convenient for users to build a flexible network. It offers 24-port, and 48-port access and all ports support Gigabit wire speed forwarding capabilities to meet users’ needs.
- The virtualization technology allows each slave device in the stack to serve as the backup of the master, creating control and data link redundancy, as well as uninterrupted layer-3 forwarding. This improves the reliability, avoids unplanned business downtime and serves to improve overall performance. When the master device fails, traffic remains uninterrupted.
- Support ARP Detection, which can prevent hackers or attackers from implementing “ARP spoofing attacks” through ARP packets. Support IP Source Guard, which can prevent illegal address spoofing including MAC spoofing, IP spoofing, MAC/IP spoofing, and DoS attacks. Support DHCP Snooping, which can prevent private DHCP servers and ensure the authenticity and consistency of the DHCP environment. Support port security features, which can prevent MAC address-based attacks and realize traffic permit/limit based on a MAC address.
- Support speed limit on port and traffic to prevent malicious invasion of network bandwidth and provide multiple granular management tools. Support SP (Strict Priority), WRR (Weighted Round Robin), and SP+WRR queue scheduling algorithms, and support multi-priority data transmission. Support rich IPv6 services and multiple IPv6 management tools.
- Support CLI command line, Web network management, and Telnet, making device management more convenient. And support SSH2.0 and other encryption methods, making management more secure. Support remote upgrade of devices through FTP and TFTP, SNMP v1/v2c/v3
- Energy-saving design greatly reduces device power consumption and trouble spots. Radiation is reduced to reach the standard for household electrical appliances and is harmless to humans.
