Audience

This guide is for the networking professional managing the Catalyst 2960 and 2960-S switches, hereafter referred to as the switch. Before using this guide, you should have experience working with the Cisco IOS software and be familiar with the concepts and terminology of Ethernet and local area networking.

Purpose

This guide provides the information that you need to configure Cisco IOS software features on your switch.

Catalyst 2960 and 2960-S switches run one of these images:

• The LAN base software image provides enterprise-class intelligent services such as access control lists (ACLs) and quality of service (QoS) features. On a Catalyst 2960-S switch, stacking is also supported.
• The LAN Lite image provides reduced functionality.

The Catalyst 2960-S ships with a universal image that includes cryptographic functionality. The software image on the switch is either the LAN base or LAN Lite image, depending on the switch model. To determine which image your switch is running:

• Switches running the LAN Lite image do not support the FlexStack module. They do not have a FlexStack module slot on the rear of the switch.
• On the front of the switch, the label in the top right corner ends in -S if the switch model runs the LAN Lite image.
• Enter the show version privileged EXEC command. The line that shows the product ID also ends in either -L (if running the LAN base image) or -S (if running the LAN Lite image). For example, WS-C2960S-48PD-L is running LAN base; WS-C2960S-24TS-S is running LAN Lite image.
• Enter the show license privileged EXEC command, and see which is the active image:

This guide provides procedures for using the commands that have been created or changed for use with the switch. It does not provide detailed information about these commands. For detailed information about these commands, see the Catalyst 2960 and 2960-S Switch Command Reference for this release. For information about the standard Cisco IOS Release 12.2 commands, see the Cisco IOS documentation set available from the Cisco.com home page at Documentation > Cisco IOS Software.

This guide does not provide detailed information on the graphical user interfaces (GUIs) for the embedded device manager or for Cisco Network Assistant (hereafter referred to as Network Assistant) that you can use to manage the switch. However, the concepts in this guide are applicable to the GUI user. For information about the device manager, see the switch online help. For information about Network Assistant, see Getting Started with Cisco Network Assistant, available on Cisco.com.

This guide does not describe system messages you might encounter or how to install your switch. For more information, see the Catalyst 2960 and 2960-S Switch System Message Guide for this release and the Catalyst 2960 and 2960-S Switch Hardware Installation Guide.

For documentation updates, see the release notes for this release.
