Configure Dynamic Channel Assignment (DCA) on a Cisco WLC

To disable an 802.11 wireless channel on a Cisco WLC, go to Wireless > choose 802.11a/n/ac or 802.11b/g/n > RRM > DCA > select/unselect specific Channel.

The WLC will reject the applied configuration if you don't disable first the specific 802.11 wireless standard.

To disable the wireless network go to Wireless > 802.11b/g/n > Network > under General > unselect Enabled > click Apply.

This will cause a temporary wireless outage on the selected 802.11 wireless standard.

Go back to Wireless > 802.11b/g/n > RRM > DCA > select/unselect specific Channels. For this case I unselected Channel 11 since the site was advised by the government to disable the said channel as they're using it for special purpose in the area.
