7 minutes to recover from WLC 5760 HA to primary WLC 5760
Considering the following scenario:
Both WLC are in the same subnet and running IOS XE 03.03.01SE
- In the Configuration->Wireless->Global AP Configuration we've configured the "Global AP Failover Priority" + "Back-up Primary Controller IP Address" + "Back-up Primary Controller Name" + "Back-up Secondary Controller IP Address" + "Back-up Secondary Controller Name" in both WLCs.
- Configured the primary and secondary IP address in all APs
- From a total of 47 APs, we've configured 8 of them with priority Critical, 7 APs with priority High and 3 APs with priority Medium.
We've issued an reload to the primary WLC and it took 7 minutes for the APs recover from the Secondary to the Primary
13:14 - reload issued on the primary WLC
13:15 - service granted by the secondary WLC (required an shut/no shut to the "Network Status" of the radio interfaces)
13:22 - service recovered to the primary WLC
The priority values mentioned above didn't show much improvement in the AP recovery time.
Is 7 minutes a normal recovery time for the 5760 WLC?

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

The script should be completely self explanatory.
