All rights reserved.INTRO v Summary The startup of a Catalyst switch requires verifying the physical installation, powering up the switch, and viewing the Cisco IOS software output on the console. The Catalyst switches have several status LEDs that are generally lit in green when the switch is functioning normally but turn amber when there is a malfunction. The Catalyst POST is executed only when the switch is powered up. During initial startup, if POST test failures are detected, they are reported to the console. If POST completes successfully, the switch can be configured.

The Catalyst switch CLI provides a help facility that is similar to the help facility of the router. The Catalyst IOS switches can be configured using the global and other configuration modes, similar to the routers. After logging into a Catalyst IOS switch, the switch software and hardware status can be verified using show version, show running-config, and show interfaces commands.
