During some Policy-sync attempts, the SyncStatus flag for the devices keeps toggling and status messages keep changing (In-Sync, Changes Pending, Not All devices are synced, and so on). It can take over 15 minutes for the status messages to stabilize. This might occur when there is a large delay in the Sync requests between devices most likely due to WAN.


Policy sync is successful. Only the Sync Status flag on the GUI keeps toggling.


Geographically distributed devices in the policy-sync device-group where network delay makes the sync infrastructure susceptible to issues like this.


None. The fluctuations stop after some time.

Fix Information

APM now prevents the retransmission of policy sync requests that caused status messages to fluctuate.
