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. Storm suppression prevents broadcast,
multicast, and unknown unicast traffic storms from engulfing the network.
Untagged (port-based) and tagged 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 a TFTP server (using the
console interface), and later download this file to restore the switch
configuration settings.

UTHENTICATION
This switch authenticates management access via the console port, Telnet,
or a web browser. User names and passwords can be configured locally or
can be verified via a remote authentication server (i.e., RADIUS or
). Port-based authentication is also supported via the IEEE
802.1X protocol. This protocol uses Extensible Authentication Protocol over
LANs (EAPOL) to request user credentials from the 802.1X client, and then
uses the EAP between the switch and the authentication server to verify
the client’s right to access the network via an authentication server (i.e.,
RADIUS server).
Other authentication options include HTTPS for secure management access
via the web, SSH for secure management access over a Telnet-equivalent
connection, SNMP Version 3, IP address filtering for web/SNMP/Telnet/SSH
management access, and MAC address filtering for port access.
Virtual LANs Up to 256 using IEEE 802.1Q, port-based, and private VLANs
Traffic Prioritization Queue mode and CoS configured by Ethernet type, VLAN ID, TCP/
UDP port, DSCP, ToS bit, VLAN tag priority, or port
