Parameters

Name	Meaning
[oid]	Indicates the MIB object ID of the alarm.
hwClockSrcSelChassisIndex	Indicates the index of the chassis where the clock source resides.
hwClockSrcSelType	Indicates the type of clock source selection. The value can be: System(0): system phase-locked loop sync2M-1(1): 2M phase-locked loop-1 sync2M-2(2): 2M phase-locked loop-2
hwClockChassisId	Indicates the ID of the chassis where the clock source resides.
hwClockPllId	Indicates the clock source type ID.
hwClockLastSourceName	Indicates the last clock source name.
hwClockCurSourceName	Indicates the current clock source name.
hwClockSourceSelMode	Indicates the mode of clock source selection. The value can be: auto(0): automatic clock source selection manual(1): manual clock source selection force(2): forcible clock source selection

Impact on the System

If the clock source is switched to an empty source, the clock signal accuracy will degrade.
If the new clock source provides clock signals of better qualities, services will not be affected.
If the new clock source provides clock signals of poorer qualities, the clock signal accuracy will degrade.

Possible Causes

The attribute of a clock device on the network was changed, which caused the switch of the clock source.
An associated link failed or an associated interface became Down, which caused the switch of the clock source.
The clock source was manually switched when the clock source selection mode was manual or force.

Procedure

Run the display clock source command to check the operating mode of the clock source.
- If the operating mode is free, it indicates that the clock source is in the free oscillation state. Then, go to Step 6.
- If the operating mode is hold, it indicates that the clock source is in the hold state. Then, go to Step 6.
- If the operating mode is normal, go to Step 2.
Run the display clock config command to check the clock source selection mode.
- If the clock source selection mode is manual or force, it indicates that the clock source is switched forcibly. Then, go to Step 6.
- If the clock source selection mode is auto, go to Step 3.
Run the display clock source command to check whether the clock source is in the normal state.
- If the clock source is not in the normal state, go to Step 5.
- If the clock source is in the normal state, go to Step 4.
Run the display clock source command to check whether the attributes of the clock source are changed.
- If so, go to Step 6.
- If not, go to Step 5.
Collect alarm information and configuration information, and then contact technical support personnel.
