hi

Can someone advise me why this has happend and what are the required configurations needed to work active/standby or share the AP association between two controllers.
thanks in advance !

Mobility must be configured and working properly. Here are some links to help you out. AP Fallback also muct be configured and I put a link here also:

What is the Firmware of the two WLC?
If v3.x/4.x/5.x (before 5.2), try the following commands from the WLC:
config ap primary-base
config ap secondary-base
This forces the AP to "point" to the primary/secondary WLC immediately after bootup.
If your Firmware is 5.2, then use the command:
config advanced backup-controller primary
config advanced backup-controller secondary
Does this help?
