Parameter Description
ap-name <ap-name>
Show ARM history for an AP with a specific name.

Show ARM history for a specific Basic Service Set Identifier (BSSID) on an AP.
An AP’s BSSID is usually the AP’s MAC address.

Examples
Adaptive Radio Management (ARM) can automatically change channel and power levels based on a number of
factors such as noise levels and radio interference. The output of the show ap arm history command shows
you an AP’s channel and power changes over time, and the reason why those changes took place.
