Local Local Rudendancy - Users IP address issue

Hi ,

i have two controllers configured in with local local redundancy

the issue is

when Controller B fail , AP goes to Controller A  and users gets new IP address Normally.

but when controller B come back , Users holds IP  obtained from DHCP that is attached to controller A.

how can I fix it.

Are you using HA? If yes, the access points should deauth the clients upon fail over, forcing them to get another opinion address...

When using lms backup lms (older redundancy), the access point does not send deauths to the clients when it fails over, so it is expected that the clients are on the same vlan.  You could try turning on cpsec and see if it makes a difference...
