(ARM).
Syntax
Parameter Description
ap-name <ap-name>
Show ARM history for an AP with a specific name.
bssid <bssid>
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.
ip-addr <ip-addr> Show ARM history for an AP with a specific IP address. Enter the IP address in dotted-

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.
