3. The interface used for clock synchronization is forcibly shut down.

4. The signal type was improperly configured for the external clock source.

Procedure

  1. View the name of the clock source to determine the type of the clock source.

    • If the clock source is a line clock source, go to step 2.

    • If the clock source is an external clock source, go to step 3.

    • If the clock source is a PTP clock source, go to step 8.

  2. Check whether the link is properly connected and the indicator is on.

    • If so, go to step 4.

    • If not, go to step 10.

  3. Run the display clock config command to check whether the clock signal types of the external clock sources are the same. The clock signal type can be 2mbps or 2mhz.

    • If so, go to step 6.

    • If not, go to step 9.

  4. Run the display interface brief command to check whether the directly connected interfaces are shut down.

    • If not, go to step 10.

  7. Run the clock bits output-threshold command on the peer end to restore the default threshold or decrease the threshold.
  8. Run the clock bits-type bits0/1 command to configure the signal type as 2mbps or 2mhz on both ends. Go to step 11.
  9. Configure the clock again. For details, see 1588v2 Configuration in Configuration Guide - System Management. Go to step 11.
  10. Collect alarm information and configuration information, and then contact technical support personnel.
  11. End.

Procedure

  1. Run the display clock config command to check the threshold of the SSM level of the output clock signal.

    • If the bits output threshold field displays dnu, no output threshold is set. Go to step 3.

    • If the bits output threshold field is displayed as another value, go to step 2.

  2. Run the display clock source command to check the output SSM level of the clock source.

    • If the output SSM level is below the threshold, run the clock source ssm command in the system view or run the clock ssm command in the interface view to change the output SSM level threshold.

    • If the output SSM level is not below the threshold, go to step 3.

  3. Collect alarm information and configuration information, and then contact technical support personnel.

CLKMIB_1.3.6.1.4.1.2011.5.25.186.1.8.7 hwClockNotInLockedMode

Description

CLKMIB/4/SYSCLKNOTINLOCKEDMODE: OID [oid] The work mode of system clock is not in locked mode.(hwClockAttributeChassisIndex = [integer], hwClockChassisId = [integer],hwClockSourceSysClkWorkMode = [integer])

The clock source was out of lock.

Attribute

Alarm ID Alarm Severity Alarm Type
1.3.6.1.4.1.2011.5.25.186.1.8.7 Warning equipmentAlarm(5)

Parameters

Name Meaning

[oid]

 Indicates the MIB object ID of the alarm.

hwClockChassisId

Device ID

hwClockSourceSysClkWordMode

Working mode of the clock source

Impact on the System

The device fails to synchronize the clock with other devices configured with a higher SSM quality level.

Possible Causes

  1. No external clock source was available to trace.
  2. The external clock source failed to be traced due to poor quality. For example, frequency offset occurs.
  3. The clock source tracing mode was forcibly specified as free.

Procedure

  1. Run the display clock config command to check whether the working mode of the clock source is normal.

    • If yes, go to Step 2.

    • If not, go to Step 4.

  2. Run the display clock source command to check whether a clock source is available for tracing. For example, check whether the clock source status is normal, whether the user is configured with a priority, and whether the clock source is configured with an available SSM quality level.

    • If a clock source is available for tracing, go to Step 5.

    • If no clock source is available for tracing, go to Step 3.

  3. Reconfigure the clock attributes on the local interface. For details, see Synchronous Ethernet Configuration in "Configuring Synchronous Ethernet" of S2720, S5700, and S6700 V200R019C10 Configuration Guide - Device Management Configuration Guide.
  4. Run the clock run-mode normal command to configure the working mode of the clock source as normal and check whether the configuration result is successful.

    • If yes, go to Step 2.

    • If not, go to Step 5.

  5. Collect alarm information and configuration information, and then contact technical support personnel.
  6. End.

CLKM_1.3.6.1.4.1.2011.5.25.186.1.8.26 hwClockSsmPktLos

Description

CLKM/3/CLOCKSSMPACKETLOS:OID [oid] The ssm packet of clock source is lost. (hwClockCurSourceName = [STRING])

ESMC packets were lost.

Attribute

Alarm ID Alarm Severity Alarm Type
1.3.6.1.4.1.2011.5.25.186.1.8.26 Major equipmentAlarm(6)

Parameters

Name Meaning
[oid] Indicates the MIB object ID of the alarm.

hwClockCurSourceName

Name of the current clock source

Impact on the System

In standard SSM mode, the local interface failed to obtain the SSM quality level of the peer interface, and the clock status of the local interface was abnormal.

Possible Causes

In standard SSM mode, the Ethernet interface in the clock source list failed to receive ESMC packets within 5 seconds.

Procedure

  1. Run the display clock config command on the peer device and check whether the clock synchronization function is enabled on the peer interface.

    • If yes, go to Step 3.

    • If no, go to Step 2.

  2. Run the clock synchronization enable command on the peer interface and check whether the ESMC packet loss alarm is cleared on the local interface.

    • If the alarm is cleared, go to Step 4.

    • If the alarm persists, go to Step 3.

  3. Collect alarm information and configuration information, and then contact technical support personnel.
  4. End.
