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. Storm suppression prevents broadcast, multicast or unknow 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.
Configuration Backup and Restore – You can save the current configuration
settings to a file on an FTP/TFTP server or to a management station using a web
browser, 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 the 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.
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 SNMP/web/Telnet management access.
MAC address filtering and IP source guard also provide authenticated port access.
While DHCP snooping is provided to prevent malicious attacks from insecure ports.
Virtual LANs Up to 255 using IEEE 802.1Q, port-based, protocol-based, and private
VLANs
Traffic Prioritization Default port priority, traffic class map, queue scheduling, or Differentiated
Services Code Point (DSCP)
Quality 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, as well as Multicast VLAN Registration
Switch Clustering Supports up to 36 member switches in a cluster
Tunneling Supports IEEE 802.1Q tunneling (QinQ)
