Description of Software Features
The switch provides a wide range of advanced performance enh ancing
features. Flow control eliminates the loss of packets due to bottlenecks
caused by port saturation. Broadcast storm suppression pr events broadcast
traffic storms from engulfing the network. Port-based and protoco l-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.
Configuration Backup and Restore – You can save the current
configuration settings to a file on a TFTP server, and later download this
file to restore the switch configuration settings.
Authentication – This switch authenticates management access via the
console port, Telnet or 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 Authent ication
Protocol over LANs (EAPOL) to request a user name and password 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.
Other authentication options include HTTPS for secure management
access via the web, SSH for secure management access over a
Telnet-equivalent connection, IP address filtering for SNMP/web/Telnet
management access, and MAC address filtering for port access.
Access Control Lists – ACLs provide packet filtering for IP frames
(based on address, protocol, TCP/UDP port number or TCP cont rol
code) or any frames (based on MAC address or Ethernet type). ACLs can
