Tính năng kỹ thuật :

Ports : 24 autosensing 10/100/1000 PoE+ ports (Công suất tối đa :370W, port : 30W); 4 Gigabit SFP ports.

Memory and processor : MIPS @ 500 MHz, 32 MB flash, 128 MB SDRAM; packet buffer size: 4.1 Mb.

Performance : 100 Mb Latency < 5 µs; 1000 Mb Latency < 5 µs; Throughput up to 41.7 million pps; Routing/Switching capacity 56 Gbps; Routing table size 32 entries.

Support : Quality of Service (QoS); Management; Connectivity; Layer 2 switching; Security; Convergence; Resiliency and high availability.

Layer 3 services : Address Resolution Protocol (ARP): determines the MAC address of another IP host in the same subnet; supports static ARPs; gratuitous ARP allows detection of duplicate IP addresses; proxy ARP allows normal ARP operation between subnets or when subnets are separated by a Layer 2 network; DHCP relay: simplifies management of DHCP addresses in networks with multiple subnets.

Layer 3 routing : NEW Static IPv4/IPv6 routing: provides basic routing (supporting up to 32 static routes and 8 virtual VLAN interfaces); allows manual configuration of routing.
