CLOCK/4/SYNC_FAIL:The clock synchronization fails.


The time synchronization condition of the clock board degrades.



Possible Causes

The performance of the traced clock source degrades or the jitter occurs.


  • Check whether the clock configurations of the upstream device and downstream device are correct and whether the output mode of the upstream device is the same as the input mode of the local device (bit/hz).
  • Check the frequent offset of the upstream clock source. The tool may be required.
  • After the clock source is switched, if the log is generated on all interfaces of the local device, the local clock board may be faulty. Then perform an active/standby switchover on the clock boards.
  • Record this log message and contact technical support personnel.
