This chapter contains an alphabetical listing of all switch and ROM monitor commands available on the Catalyst 5000 family, 4000 family, 2926G series, 2948G, and 2980G switches.
Use the alias command to set and display aliases.

This example shows how to display a list of available alias commands and how to create an alias for the set command:
rommon 1 > alias r=repeat h=history ?=help b=boot ls=dir i=reset k=stack rommon 2 > alias s=set rommon 3 > alias r=repeat h=history ?=help b=boot ls=dir i=reset k=stack s=set rommon 4 > s PS1=rommon ! > BOOT=bootflash:RTSYNC_llue_11,1;slot0:f1,1; =========================================================================
