The customer has requested that we have this ticket created, to help investigate the reported policy mismatch seen on the Symantec Management Center, for a specific policy/device.
If you receive a Mismatch error for a device, it means that the policy is inconsistent: Either the policy was changed in Management Center and not installed to the device with the error, or the policy on the device was changed outside of Management Center.
You can click Compare Policy to determine what has changed.
As a troubleshooting step or as part of a performance evaluation, you might want to identify the changes between an earlier version and a later version of the policy.
You can diff the source code of the VPM policy. To switch between the Generated CPL and XML views, select the appropriate window.
Note: To view all text changes, including rule index, and timestamp changes, click the Generated CPL (Verbose) tab.
The two policies are displayed side by side; the web console displays the earlier version on the left and the later version on the right.
Please note that while comparing the policies, it's not possible to edit the policies from the "Compare Policy" interface. The whole idea here is to be able to identify the inconsistencies and then manually update the policy or restore the earlier version, before the change.
