show ap arm history
show ap arm history {ap-name <ap-name>}|{bssid <bssid>}|{ip-addr <ip-addr>}
Description
For each interface on an AP, show the history of channel and power changes due to Adaptive Radio Management
(ARM).
Syntax
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.
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-decimal
format.
