Parameter Sequence Number Description The number of times the local controller in the whitelist received and acknowledged a campus AP whitelist change from the master controller. In the example above, both local controllers received and acknowledged three campus AP whitelist changes sent from the master controller. Remote Sequence Number The number of times that the master controller has received and acknowledged a campus AP whitelist change from the local controller in the whitelist. In the example above, the master controller received and acknowledged a single campus AP whitelist change from the local controller with the MAC address 00:0b:86:51:a5:4c. Null Update Count The number of times the controller has checked its control plane security whitelist and found nothing to synchronize with the remote controller. By default, the controller compares its control plane security whitelist against whitelists on other controllers every minute. If the null update count reaches 5, the controller will send an "empty sync" heartbeat to the remote controller to ensure the sequence numbers on both controllers are the same, then reset the null update count to zero.
