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
provides support for real-time network applications.
Some of the management features are briefly described below.
Congestion Control Rate Limiting
Throttling for broadcast, multicast, unknown unicast storms
Random Early Detection
Address Table 8K MAC addresses in the forwarding table, 1K static MAC
addresses, 255 L2 multicast groups
IP Version 4 and 6 Supports IPv4 and IPv6 addressing, and management
IEEE 802.1D Bridge Supports dynamic data switching and addresses learning
Store-and-Forward
Switching
Supported to ensure wire-speed switching while eliminating bad
frames
