AP Can not join to Primary LMS From Backup LMS

Hi All,


I've deployed some AP, joining to Primary LMS MD with  AOS: and Backup LMS with AOS:


When the Primary WLC geting down, all AP joint to Backup LMS. then primary WLC already UP and running well. All AP stuck can not joint to my Primary WLC.


My question is?

This issue is because my LMS are on defferent AOS or there are traffic block on Firewall (something like that).


Thanks you for your feedback on this.

You cannot have an AP connect to two controllers with different AOS versions, because there will be an upgrade/downgrade loop.
