Description

The clock board can perform distinct adjustment or fine tune on internal clock. This log is generated only when the clock board performs distinct adjustment. The log records the counts of distinct adjustment and fine tune.

Parameters

Parameter Name	Parameter Meaning
[ULONG]	Indicates the distinct adjustment count.
[ULONG]	Indicates the tiny adjustment count.

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.

Possible Causes

1. On the clock boards, the number of times the time stamp is adjusted exceeds a certain value.

2. If the time source is changed from the external time source to the local time source, this log is generated. It is normal.

Procedure

Run the display clock mode command to check whether the traced time source is correct, and run the display clock source command to check whether the status of each time source is correct.
If the preceding information is correct, Collect log information and configuration information, and then contact technical support personnel. You can collect diagnostic information using the display diagnostic-information command.

Parameter Name	Parameter Meaning
[ULONG]	Indicates the number of unchanged T1 time stamps.
[ULONG]	Indicates the number of unchanged T2 time stamps.

Possible Causes

1. An error occurs on the upstream interface that transmits signal. As a result, the time stamps are not updated.

2. The channel for receiving time stamps on the clock source is closed. As a result, the clock source cannot receive the updated time stamps.

Procedure

Run the clock force source command to change the clock source and then check whether this log is generated on all interfaces of the local device.
- If so, the clock board of the local device is faulty. Perform an active/standby switchover of clock boards and go to step 2.
- If not, go to step 3.
Check whether this log persists.
- If so, go to step 3.
- If not, the alarm handling ends.
Collect log information and configuration information, and then contact technical support personnel. You can collect diagnostic information using the display diagnostic-information command.
