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. Storm suppression prevents broadcast,
multicast, and unknown unicast 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.

You can save the current configuration settings to a file on the
management station (using the web interface) or an FTP/TFTP server
(using the web or console interface), and later download this file to restore
the switch configuration settings.
