My query is to understand how much time will an AP take to failover to its secondary WLC(Backup) incase primary goes offline.
We can not tell exact time but normally It takes 1-3 minutes.
Whats the heartbeat time for each AP to verify reachability to WLC.
AP Heartbeat Timeout - AP sends heartbeat to WLC (By default its 30s). Once the primary WLC(or where AP is connected to)goes down, With heartbeats, the AP realizes sooner that the controller has become unreachable.
also what is the purpose of AP Fail over priority under each AP.
First of all there are three types: it goes like this Cirtical...high...medium..low.
***To configure AP failover priority, we must enable AP Fallback feature globally and then individual APs with a suitable priority level.
*** When using both the local and global backup configurations, the locally configured settings take precedence in the event of a controller failure. If an AP is not able to join any of the locally configured controllers, it then tries to join the global backup controllers.

The 1st installment is a table of advanced filters. More filters will be added as time allows.
