PTP/2/hwPtpFrequencyLockFail_active

Message

PTP/2/hwPtpFrequencyLockFail_active: Current lock status of clock frequency synchronization failed. (hwPtpFreqLockStatus=[hwPtpFreqLockStatus])

In VS mode, this log is supported only by the admin VS.

Description

Frequency out-of-lock alarm.

Parameters

Parameter Name	Parameter Meaning
hwPtpFreqLockStatus	Frequency locking status of the clock. The values are as follows: unlock(0). lock(1).

Parameter Name

Parameter Meaning

hwPtpFreqLockStatus

Frequency locking status of the clock. The values are as follows:

unlock(0).

lock(1).

Possible Causes

Cause 1: During frequency synchronization based on synchronous Ethernet, the reference frequency source has an excessive frequency deviation.

Cause 2: During frequency synchronization based on IEEE 1588v2, timestamps are incorrect.

Cause 3: The DSP internal frequency control word exceeds +/-10 ppm.

Procedure

1. Run the display clock source command to check whether the clock synchronization source is a PTP source, that is, whether the value of Current system trace source is ptp.

If yes, the fault is caused by cause 1. Go to step 2.
If not, the fault is caused by Cause 2. Go to Step 3.

2. Run the display current-configuration command to check whether PTP configurations are changed.

If yes, re-configure the PTP attributes on the local end. For details, refer to the chapter "1588v2 Configuration" in the Configuration Guide - System Management.
If no, go to Step 4.

3. Run the display clock config command to check whether the clock source configuration is changed.

If yes, configure the attributes of the local clock. For details, refer to the chapter "Clock Synchronization Configuration" in the Configuration Guide.
If no, go to Step 4.

4. Collect trap, log, and configuration information, and contact Huawei technical support personnel.

5. Ends.
