If channel change occurs due to radar detection (
R
), identify the DFS channels pertaining to the AP country
code and configure valid channels in the ARM profile accordingly.
Use the
show ap allowed channels
command to view the list of allowed channels and identify the
DFS channels of the AP. Remove those channels from the list of
Valid 5 GHz channels
and
Valid 2.4 GHz
channels
in
ARM Advanced options
in the
Configuration > RF
page of the Instant WebUI.
The sample below displays the list of allowed channels for the AP, generated by the
show ap allowed
channels
command:
(Instant AP)# show ap allowed-channels
