The Command Prompt
Using the Switch Console
Interface
Set and Show Commands
Most of the commands at the command prompt are useful for diagnostics
purposes, but the set commands can be used to configure some of the switch’s
basic features, and the show commands can be used to display switch and port
status and activity information. These commands can be run from UNIX
scripts so they can be executed on an automatic, timed basis.
To get help on the set and show commands, type help at the end of the
command line; for example show help to display help for the show command,
or set spantree hello help to display help on how to configure the Spanning Tree
Hello Time parameter.
