Hey Sai Prasad,

This usually indicates a misconfiguration with the vlan tagging.  Are you locally bridging or tunneling on the wlan(s)? 

If you have a support contract I would be happy to remote in and take a look if you can provide access.

There are 50 of them showing this error, out of 200 access points booted on secondary controller.

And the bridging mode is "local" on wlans

Hi Sai,

Can you provide the output of 'show adoption status' for these APs that are showing an error? This generally indicates that the config from the controller caused the AP to lose communication with the controller. You can also check 'show adoption config-errors <AP Hostname>' to see what the specific error is.

And the bridging mode is "local" on wlans

sh adoption config-errors <AP-NAME> gives output as *** No configuration errors

Hey Sai,

Sorry for the late reply. 

I would like to take a look at the tech support when you a get a chance.  Is there an email I can reach you at?
