CLOCK/4/STOP_SLOT_SRC:The slot [ULONG] stops delivering clock signal to the clock board.


During clock source selection in a frame, a slot stops sending clock signals.


Parameter Name Parameter Meaning


Specifies the slot ID.

Possible Causes

1. The clock source is switched to another slot according to the source selection rule.

2. The frame priority of the interface is deleted.

3. The interface becomes Down.

4. The interface is a 1000M electrical interface.

5. The interface is configured with loopback.


  • If the clock source is switched to another slot in the same frame, the log is normal.
  • If the log is generated in other cases, do as follows:
    1. Run the display interface interface-type interface-number command to check whether the interface is in Down state. If so, rectify the fault to ensure that the interface is Up.
    2. Run the display interface interface-type interface-number command to check whether the interface is a 1000M electrical interface. The 1000M electrical interface does not support Ethernet synchronization. Do not use this type of interface.
    3. Check whether the loopback internal command is configured on the interface. If so, cancel the configuration.
    4. Check whether the interface has the frame priority configured using the clock { left-frame | right-frame } priority command. If not, configure the frame priority for it.
    5. 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.
