These Layer 2 Ethernet switches are designed for enterprise networks demanding high security and intelligence. They provide 10/100 Mbps downlink and 1000 Mbps uplink Ethernet ports, and serve as access devices for 100 Mpbs-to-desktop applications in enterprise networks. In metropolitan area networks or various industry networks, they connect end users or aggregate client devices with 10/100 Mbps connections, converging at a higher capacity switch with 1000 Mbps interfaces. Features include advanced quality of service (QoS), rate limiting, QinQ (virtual LAN [VLAN]/VPN), SSHv2, Multicast VLAN Registration (MVR), Virtual Cable Test (VCT), HGMP V2, GARP VLAN Registration Protocol (GVRP), access control list (ACL), media access control (MAC)-IP-port binding, and Endpoint Admission Defense, voice and protocol-based VLAN, Internet Group Management Protocol snooping, and Power over Ethernet (PoE)

Quality of service (QoS)

• Broadcast control: allows limitation of broadcast traffic rate to cut down on unwanted broadcast traffic on the network


Management

• Friendly port names: allow assignment of descriptive names to ports


Connectivity

• Auto-MDIX: automatically adjusts for straight-through or crossover cables on all 10/100 and 10/100/1000 ports


Performance

• Hardware-based wire-speed access control lists: feature-rich ACL implementation (TCAM based) helps ensure high levels of security and ease of administration without impacting network performance


Resiliency and high availability

• Separate data and control paths: increases security and performance


Layer 2 switching

• 8K MAC addresses: provide access to many Layer 2 devices


Layer 3 services

• ARP: determines the MAC address of another IP host in the same subnet
