When we use Huawei NE series routers, we sometimes encounter problems. How can these problems be solved? We provide the Troubleshooting Guide to help you.
If you encounter the Clock Synchronization Fails After the 1588 ACR Negotiation, perform the following steps:
1. Run the display clock config command on the client to check whether the PTP clock source is in the Sync enable state.
§ If the PTP clock source is in the Sync disable state, run the clock source ptp synchronization enable command to enable PTP clock source synchronization.
§ If the PTP clock source is in the Sync enable state, go to Step 2.
2. Run the display clock source command on the client to check whether PTP clock source configurations are correct.
§ If the clock source is selected based on the SSM levels on the client, check whether the In-SSM value of the PTP clock source is correct. If the In-SSM value is incorrect, run the clock source ptp ssm command in the system view to set a correct In-SSM value.
§ If the clock source is selected based on the priorities on the client, check whether the priority of the PTP clock source, identified by the Pri(sys) field, is correct. If the priority is incorrect, run the clock source ptp priority priority-value command in the system view to set a correct priority.
If PTP clock source configurations are correct, go to Step 3.
3. Run the display ptp-adaptive server command on the client to check whether the Sync packet statistics are displayed in the Receive packet statistics field.
§ If the statistics about both Sync and Delay_resp packets are collected, go to Step 4.
§ If the statistics about Sync packets are not collected, the client fails to receive Sync packets, go to Step 5.
4. Check whether the clock synchronization negotiation on the client has been successful for 30 minutes.
§ If the clock synchronization negotiation has been successful for less than 30 minutes, the clock synchronization on the subcard may not be complete.
§ If the clock synchronization negotiation has been successful for 30 minutes, go to Step 5.
5. Collect the following information and contact Huawei technical support personnel.
§ Results of the troubleshooting procedure
§ Configuration files, log files, and alarm files, and PDV data statistics for the devices
§ Type of the subcard on the client
