DESCRIPTION OF SOFTWARE FEATURES
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. Broadcast storm suppression prevents
broadcast 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.
CONFIGURATION
BACKUP AND
RESTORE
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.
AUTHENTICATION 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
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 4094 using IEEE 802.1Q, port-based, protocol-based,
voice VLANs, and QinQ tunnel
Traffic Prioritization Default port priority, traffic class map, queue scheduling, IP
Precedence, 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 and query, and Multicast VLAN
Registration
Switch Clustering Supports up to 36 member switches in a cluster
Connectivity Fault
Management
Connectivity monitoring using continuity check messages, fault
verification through loop back messages, and fault isolation by
examining end-to-end connections (IEEE 802.1ag)
ERPS Supports Ethernet Ring Protection Switching for increased
availability of Ethernet rings (G.8032)
Remote Device
Management
Supports Ethernet OAM functions for attached CPEs
(IEEE 802.3ah, ITU-T Y.1731)
