Command Summary.
For task-oriented configuration steps, refer to the Catalyst 2950 Desktop Switch Software Configuration
Guide for this release.
The switches are preconfigured and begin forwarding packets as soon as they are attached to compatible
devices.
By default, all ports belong to virtual LAN (VLAN) 1. Access to the switch itself is also through
VLAN 1, which is the default management VLAN. The management VLAN is configurable. You
manage the switch by using Telnet, Secure Shell (SSH) Protocol, web-based management, and Simple
Network Management Protocol (SNMP) through devices connected to ports assigned to the management
VLAN.
Type of Memory
The switch Flash memory stores the Cisco IOS software image, the startup and private configuration
files, and helper files.
Platforms
This IOS release runs on a variety of switches. For a complete list, refer to the Release Notes for the
