Hi, we have 2 controllers which are configured as master and local, and use clearpass to do client authentication. LMS IP /backup lms IP are already set in AP system profile. Master and local controllers are all added to Clearpass as network devices. Now when AP connected to master controller, the authentication successful, but when connect to local controller, all client cannot be authenticated, and no incoming authentication request is received on ClearPass. Please advise the possible cause. Thanks.
