C25 failover mode, AP's stay on non-failed controller even after the failed controller came back up.


Hi, I'm using 2 C25 controllers in fast failover mode. Now I had to reboot one of the controllers, but it seems the other one doesn't seem to recognize that the failed one is back operational and all the AP's are now are now active on one controller. I remember from previous tests that after a failed controller comes back up, the AP's of the failed controller came back active on their local controller. Am I missing something? Kind regards, Danny

Found it, I had to release the foreign AP's on the non failed controller. (A case of RTFM :)).

Welcome to The Hub, Danny. Thanks for coming back to update the thread!

Yes it is expected behavior. The reason is quite simple. Each flap from one controller to another may have impact on user traffic = b@ewc or routed topology. It is better to leave this on admin to choose when release the AP back.
