Controller Based WLANs

Environment         Master-Local Controller topology from which a local controller has been decommissioned.

There would be scenarios where a Local is removed from a Master-Local cluster (example : To make standalone Master / Remove Lab controller after syncing config from production) . In such scenarios; it would be ideal to clean up entries related to the Local controller on the Master.

Following is the procedure to clear AP Database and Switch Entry.
