CLOCK/4/OFFSET_ABNORMAL
Message
CLOCK/4/OFFSET_ABNORMAL:The time offset is abnormal. (Up400nsCount=[ULONG], 200ns-400nsCount=[ULONG], 100ns-200nsCount=[ULONG], 50ns-100nsCount=[ULONG])
Parameters
Parameter Name | Parameter Meaning |
---|---|
[ULONG] |
Indicates the number of times the time offset becomes greater than 400ns. |
[ULONG] |
Indicates the number of times the time offset is between 200ns and 400ns. |
[ULONG] |
Indicates the number of times the time offset is between 100ns and 200ns. |
[ULONG] |
Indicates the number of times the time offset is between 50ns and 100ns. |
Possible Causes
1. Generally, jitter occurs during the switchover of clock source. This log is generated when the jitter occurs.
2. The performance of the traced clock source degrades, for example, the time jitter occurs.
Procedure
- If the clock source is switched, this is a normal situation.
- If the clock source of the upstream device is switched, this is a normal situation.
- After the clock source is switched, if the log is generated on all the interfaces of the local device, the clock board of the local device may be faulty. Then perform an active/standby switchover. If the log does not occur, the original active clock board is faulty. You can replace the clock board.
- Record this log message and contact technical support personnel.
