Opened: Apr 29, 2015
Severity: 3-Major


After changing the Application Language for a Security Policy and pushing the changes over a manual sync device group, the device group's status immediately returns to "Changes Pending". Additionally calls through the REST interface erroneously allowed a client to change the language for a policy where it was already set.


1) The change to encoding is not seen if looking at the result in tmsh. 2) In a manual sync group, after the change has been pushed to its peers, the change is correctly written to the MCP configuration when it is loaded. This appears as a new pending change from the peer device, and the device group appears out of sync again.


A Security Policy was set to "Auto-Detect" the Application Language, and then set to a specific encoding. Or an application language is already set and is changed through the REST API. Issue is seen most prominently in a device group when ASM sync is enabled on a Manual Sync Failover Group


Push another sync from the peer to the original device.

Fix Information

Changes to Language encoding are now validated and propagated correctly.
