changes to the other controllers on the network. If all other controllers on the network have successfully
received and acknowledged all whitelist changes made on that controller, every entry in the sequencenumber
column in the local controller or master controller whitelists has the same value as the sequence number
displayed in the AP Whitelist Sync Status field. If a controller in the master or local controller whitelist has a
lower sequence number, that controller may still be waiting to complete its update, or receive its update
acknowledgment. In the example in Figure 6, the master controller has a current sequence number of 3, and
each sequence number in its local controller whitelist also shows a value of 3, indicating that both local
controllers have received and acknowledged all three campus AP whitelist changes made on the master
controller. For additional information on troubleshooting whitelist synchronization, see Verifying Whitelist
Synchronization on page 144.
You can view a controller’s current sequence number via the CLI:
(host) #show whitelist-db cpsec-seq

The following sections describe the commands to view and delete entries in a master or local controller

IP-Address On a local controller whitelist: IP address of the master controller.
On a master controller whitelist: IP address of a local controller.
Sequence Number The number of times the controller in the whitelist received and
acknowledged a campus AP whitelist change from the controller whose
WebUI you are currently viewing.
For deployments with both master and local controllers:
l The sequence number on a master controller should be the same as the
remote sequence number on the local controller.
l The sequence number on a local controller should be the same as the
remote sequence number on the master controller.
Remote Sequence Number The number of times that the controller whose WebUI you are viewing
received and acknowledged a campus AP whitelist change from the
controller in the whitelist.
For deployments with both master and local controllers:
