Parameter Description
Number
AP whitelist change from the master controller in the whitelist. In the example above, the
local controller received and acknowledged three campus AP whitelist updates from the
master controller.
Null Update Count
The number of times the controller has checked its control plane security whitelist and
found nothing to synchronize with the master 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.
