Description: The query of the status of data synchronization between the active and standby control boards. Data synchronization between the active and standby control boards refers to that when the active and standby control boards work normally. The data on the standby control board is synchronized with that on the active control board.The data synchronization between the active and standby boards has the following status: Options: 1. synccompleteness(1) -indicates that synchronization complete. 2. flashsyncincompleteness(2) -indicates that operation (loading/backuping/ duplicating/saving/...) is being performed. 3. configbasicdatasyncincompleteness(3) -indicates that configuration data or basic operation data synchronized incompletely. 4. syncswitchoff(4) -indicates that the synchronization switch off. 5. peerboardfailure(5) -indicates that the standby board doesn't exist or fail. 6. dynamicdatasyncincompleteness(6) -indicates that dynamic service data synchronization is incomplete. 7. patchinconsistent(7) -indicates that patch files of active board and standby board are inconsistent. 8. patchinconsistentdynamicdatasyncincompleteness(8) -indicates that patch files of active board and standby board are inconsistent and dynamic service data synchronization is incomplete.
