Using the Command-Line Interface
The Catalyst 2950 and 2955 switches are supported by Cisco IOS software. This chapter describes how
to use the switch command-line interface (CLI) to configure the software features.
For a complete description of the commands that support these features, see Chapter 2, “Catalyst 2950
and 2955 Cisco IOS Commands.” For more information on Cisco IOS Release 12.1, see the command
references for Cisco IOS Release 12.1 at this URL:

For task-oriented configuration steps, see the software configuration guide for this release.
The switches are preconfigured and begin forwarding packets as soon as they are attached to compatible
devices.
Note In this document, IP refers to IP version 4 (IPv4). Layer 3 IP version 6 (IPv6) packets are treated as
non-IP packets.
Type of Memory
The switch flash memory stores the Cisco IOS software image, the startup and private configuration
files, and helper files.
Platforms
This software release runs on a variety of switches. For a complete list, see the release notes.
