The clock source priority of the device is changed when the SSM quality level is not used in clock source selection.

Cause 4:

The SSM information from the upstream device is changed when the SSM quality level is used in clock source selection.

Procedure

  1. Check whether the clock switchover is performed through commands because services are adjusted.

    • If so, this alarm is informational, and the alarm handling ends.

    • If not, go to step 2.

  2. Run the display clock mode command to check whether the value of QL-Enable is Yes.

    • If so, the SSM quality level is used in clock source selection. Then go to step 11.
    • If not, the priority is used in clock source selection. Then go to step 3.

  3. Run the display clock left-frame/right-frame command to check the priority of the clock source sent from the interface and run the display clock priority command to check the priority of each clock source. Then determine whether the priority meets application requirements.

    • If so, no action is required.
    • If not, go to step 4.

  4. According to the alarm information, run the display clock source command to check the value of Signal Fail to determine whether the clock source is lost before the switchover.

    • If so, go to step 5.
    • If not, go to step 8.

  5. Check whether cables are connected properly according to the alarm information.

    • If so, go to step 8.

    • If so, no action is required.
    • If not, go to step 7.

  7. Check whether the transmit device is faulty.

    • If so, go to step 7.
    • If not, go to step 8.

  8. Check whether the path for selecting the clock source needs to be changed.

    • If so, go to step 9.
    • If not, collect alarm information and configuration information, and then contact technical support personnel.

  9. Run the clock priority, clock source priority, and clock wtr commands to adjust the path for selecting the clock source according to networking requirements and check whether the alarm on the clock switchover is received. In addition, the current clock source meets configuration requirements.

    • If so, no action is required.
    • If not, collect alarm information and configuration information, and then contact technical support personnel.

  10. Run the display clock state and display clock source commands to check the SSM information about the line clock source. Then determine whether the adjusted clock source meets application requirements.

    • If so, no action is required.
    • If not, go to step 11.

  11. According to the alarm information, run the display clock source command to check the value of Signal Fail to determine whether the clock source is lost before the switchover.

    • If so, go to step 12.
    • If not, go to step 15.

  12. Check whether cables are connected properly according to the alarm information.

    • If so, go to step 14.

  13. Connect cables again and check whether the alarm on the clock switchover is received.

    • If so, no action is required.
    • If not, go to step 14.

  14. Check whether the transmit device is faulty.

    • If so, collect alarm information and configuration information, and then contact technical support personnel.
    • If not, go to step 15.

  15. Check whether the path for selecting the clock source needs to be changed.

    • If so, go to step 16.
    • If not, no action is required.

  16. Run the clock source ssm command on the master clock device to set the quality level of the master clock or run the clock force-out-s1 command on the upstream device to adjust the path for selecting the clock source. Then check whether the alarm on the clock switchover is received and whether the clock source meets configuration requirements.

    • If so, no action is required.
    • If not, collect alarm information and configuration information, and then contact technical support personnel.

CLOCK_1.3.6.1.4.1.2011.5.25.186.1.8.2 hwClockSourceSysClkWorkModeChange

Description

CLOCK/2/WORKMODECHANGE: OID [oid] The clock work mode has changed. (ChassisId=[INTEGER], SourceOldWorkMode=[INTEGER], SoureSysClkWorkMode=[INTEGER] --- WorkMode: 1=Trace; 2=Hold; 3=Free)

The system clock status changes between tracing, holding, and free running. The clock of a device changes from tracing to free running if the object traced by the device changes from upstream clock to local oscillator. If the clock control data is saved in the memory of the device in tracing state, when the unique traced clock source is lost, the clock of the device enters the holding state. If all the clock control data in the memory is retrieved, the clock of the device switches from holding state to free running state.

CLOCK_1.3.6.1.4.1.2011.5.25.186.1.8.3 hwClockSourceStateChange

Description

CLOCK/2/SOURCESTATECHANGE: OID [oid] The clock source state has changed. (CfgChassisIndex=[INTEGER], CfgSoureIndex=[INTEGER], ChassisId=[INTEGER], CurSourceId=[INTEGER], OldSourceState=[INTEGER], CurSourceState=[INTEGER] --- SourceState: 1=Normal; 2=Abnormal)

The clock source status changes.

Check the status of the clock source according to the signal.

Check whether signals are lost.

The change of the signal sent by the clock source to the clock pinch board determines the clock source status change. The clock source refers to the device clock source rather than the line clock source. For example, if the clock source is switched from port 1 to port 2 on the left side of the frame, the notification on the clock source status change is not generated. This is because the left side of the frame is used as the same clock source of the device.
