D ESCRIPTION OF S OFTWARE F EATURES
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.
Some of the management features are briefly described below.
Address Table Up to 16K MAC addresses in the forwarding table, 1024 static MAC
addresses;
Up to 8K IPv4 and 4K IPv6 entries in the host table;
8K entries in the ARP cache, 256 static ARP entries;
8K IPv4 and 4K IPv6 entries in the IP routing table, 512 static IP
routes, 512 IP interfaces;
1024 L2 multicast groups
IP Version 4 and 6 Supports IPv4 and IPv6 addressing, and management
