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 or unknown unicast traffic storms from engulfing the network.
Port-based, protocol based and private 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.
A
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
verifies the client’s right to access the network via an authentication server.
Address Table 8K MAC addresses in the forwarding table, 1K static MAC
addresses, 256 L2 multicast groups
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
Spanning Tree Algorithm Supports standard STP, Rapid Spanning Tree Protocol (RSTP), and
Multiple Spanning Trees (MSTP)
Virtual LANs Up to 255 using IEEE 802.1Q, port-based, protocol-based, private
VLANs, and voice VLANs
Traffic Prioritization Default port priority, traffic class map, queue scheduling, or
Differentiated Services Code Point (DSCP)
Qualify of Service Supports Differentiated Services (DiffServ)
Link Layer Discovery
Protocol
Used to discover basic information about neighboring devices
Multicast Filtering Supports IGMP snooping, query, profile filtering, MLD snooping,
and Multicast VLAN Registration
Switch Clustering Supports up to 36 member switches in a cluster
Tunneling Supports IEEE 802.1Q tunneling (QinQ)
