Introduction

Description of Software Features

The switch provides a wide range of advanced performance enhancing features.

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 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 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 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,

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 control code) or any frames

(based on MAC address or Ethernet type). ACLs can by used to improve

performance by blocking unnecessary network traffic or to implement security

controls by restricting access to specific network resources or protocols.

Qualify of Service Supports Differentiated Services (DiffServ)

Router Redundancy Router backup is provided with the Virtual Router Redundancy Protocol (VRRP)

IP Routing Routing Information Protocol (RIP), Open Shortest Path First (OSPF), static routes

ARP Static and dynamic address configuration, proxy ARP

Multicast Filtering Supports IGMP snooping and query for Layer 2, and IGMP for Layer 3

Multicast Routing Supports DVMRP and PIM-DM
