Chapter 1: Introduction

This switch provides a broad range of features for Layer 2 switching and Layer 3
routing. It includes a management agent that allows you to configure the features
listed in this manual. The default configuration can be used for most of the features
provided by this switch. However, there are many options that you should configure
to maximize the switch’s performance for your particular network environment.

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 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.
