Description of Software Features
The switch provides a wide range of advanced performance enhancing features.
Flow control eliminates the loss of packets due to bottlenecks caused by port
saturation. Broadcast storm suppression prevents broadcast traffic storms from
engulfing the network. Untagged (port-based), tagged, and protocol-based VLANs,
plus support for automatic GVRP VLAN registration provide traffic security and
efficient use of network bandwidth. CoS priority queueing ensures the minimum
delay for moving real-time multimedia data across the network. While multicast
filtering and routing provides support for real-time network applications.
Address Table 16K MAC addresses in forwarding table, 1K static MAC addresses;
1K entries in ARP cache;
2K entries in ipv6 neighbor cache;
1K L2 IPv4 multicast groups
