Device > LRE Profile appears in the command-switch menu bar when at least one
Catalyst 2900 L RE XL switch is in the cluster.

information:
“Enabling a Command Switch” section on page 5-19
“Adding Member Switches” section on page 5-20

This section assumes you have already cabled the switches, as described in the switch hardware
