After a necessary change is made on the device, for example, in my case WCCP client config, FortiManager detects that the configs are now out of sync.
config system interface
set wccp enable
config system settings
set wccp-cache-engine enable
config system wccp
set cache-id x.x.x.x
set router-list "y.y.y.y"
set ports 80 443
set protocol 6
To get it to be in-sync again, the best way is not to use this “Accept” diaglog, I think the retrieve config is a better way.
To do that, Lock the Device’s ADOM
Click on Revision History, then Click on “Retrieve”.
Wait while the config is being retrieved.
Then, push it back to the device, to get the “in sync” status again.
The device is now in “Sync” again.
