G.8275.1 Troubleshooting

G.8275.1 Troubleshooting

Roadmap for Troubleshooting the G.8275.1 Dual-Master Issue

Common Causes
This fault is commonly caused by one of the following:
  • The device is not configured with G.8275.1.
  • The clock domain configurations on the device are incorrect.
  • The ptp notslave disable command has not been run on the device interface.
  • The local clock IDs at both ends at the same.
Troubleshooting Procedure

Procedure

  1. Check whether the PTP protocol used by the device is G.8275.1.

    Run the display ptp all command to check whether the PTP profile field is G.8275.1.

    • If the PTP profile field is not G.8275.1, run the ptp profile g-8275-1 enable command to enable G.8275.1 based on network planning. If the fault persists, go to Step 2.

    • If the PTP profile field is G.8275.1, go to Step 2.

  2. Check whether the domain names of the local and peer devices are the same.

    Run the display ptp all command to check whether the values of Domain value on the local and peer devices are the same.

    • If they are different, run the ptp domain domain-value command based on network planning to configure the local and peer devices to be in the same clock domain. If the fault persists, go to Step 3.

    • If the values of Domain value for the local and peer devices are the same, go to Step 3.

  3. Check whether the value of the notslave attribute is false.

    Run the display ptp all config command to check whether the ptp notslave disable command has been run on interfaces at both ends.

    • If not, run the ptp notslave disable command in the interface view based on network planning. If the fault persists, go to Step 4.

    • If yes, go to Step 4.

  4. Check whether the local clock IDs of the local and peer devices are the same.

    Run the display ptp all command to check whether the local clock IDs of the local and peer devices are the same.

    • If they are the same, an error may occur in source selection. Run the ptp virtual-clock-id command to configure the local clock IDs of the local and peer devices to be different. If the fault persists, go to Step 5.

    • If they are different, go to Step 5.

  5. Collect the following information and contact Huawei technical support personnel:

    • Results of the preceding operation procedure

    • Configuration files, log files, and alarm files of the devices
