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

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
