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 TFTP server (using the web or console interface),
and later download this file to restore the switch configuration settings.
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 TACACS+). 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 or TACACS+ server).
