This notification might be generated when the PTP port status changes in the following situations:

The clock device attributes in a PTP domain have changes, for example, the clock priority, time class, time accuracy, and interface NotSlave attribute.

The PTP port is connected to a clock source with higher priority.

The PTP port encounters a link failure or the PTP port goes down.

System impact

The clock source might be changed.

Status control

This notification cannot be disabled.

Recommended action

To resolve this issue:

1.Execute the display ptp interface command to identify whether the port is in faulty state.

  - If the port is in faulty state, it has a link failure or goes down. Execute the display interface command to view the port down reason, and locate and resolve the port down issue according to the reason.

  - If the port is not in faulty state, go to step 2.

2.Execute the display current-configuration | include ptp command to identify whether a command has been used to change clock attributes.

  - If a command has been used to change clock attributes, no action is required.

  - If no command has been used to change clock attributes, go to the next step.

3.If the issue persists, collect alarm information and configuration data, and then contact H3C Support for help.

  - If the device is not in local state, go to step 4.

2.Execute the display ptp clock command to identify whether the state of the external clock source is correct.

  - If the state is correct, go to step 3.

  - If the state is not correct, go to step 4.

3.Execute the ptp priority clock-source command to correctly configure the clock parameter attributes on the device. After that, use the display ptp clock command to identify whether the device remains in local state. If the device remains in local state, go to step 4.

  - If the device remains in local state, go to step 4.

  - If the device does not remain in local state, the issue is resolved.

4.If the issue persists, collect alarm information and configuration data, and then contact H3C Support for help.

Recommended action

1.Execute the display ptp parent command to view master node information.

  - If master node information meets the requirements, no action is required.

  - If master node information meets the requirements, go to step 2.

2.Execute the display ptp interface command to identify whether the port is in faulty state.

  - If the port is in faulty state, a link failure is present or the port has gone down. You need to locate and resolve the port issue.

  - If the port is not in faulty state, go to step 3.

3.Execute the dis current-configuration interface and display ptp interface commands to check if commands have been configured to change the clock properties of the port.

  - If such commands have been configured, no action is required.

  - If such commands have not been configured, go to step 4.

4.If the issue persists, collect alarm information and configuration data, and then contact H3C Support for help.

OID	Event	Type	Severity	Recovery notification	Default status
1.3.6.1.4.1.25506.2.235.1.0.10	Clock source class fell below threshold.	Error	Minor	1.3.6.1.4.1.25506.2.235.1.0.11 (hh3cPTPSourceClockClassRecover)	ON

 

Notification triggers

This notification is generated when the class of the clock source falls below the threshold in the following situations:

The device selects the local clock as the clock source, and the class of the local clock is below the threshold and the number of removed steps from the grandmaster clock to the local clock is 0.

The device selects the external clock source input from the ToD port as the clock source, and the class of the external clock is below the threshold.

System impact

The clock source class degrades.

Status control

This notification cannot be disabled.

Recommended action

Execute the display ptp parent command to check if the grandmaster clock class is lower than the threshold.

If it is lower than the threshold, execute the ptp priority clock-source command on the clock source device to increase the clock class or specify another clock source with a higher class.

If it is higher than the threshold, go to step 2.

If the issue persists, collect alarm information and configuration data, and then contact H3C Support for help.

Notification triggers

This notification is generated when the PTP subordinate port fails to receive Announce, Delay_Resp, or Sync messages within the timeout timer.

Recommended action

1.Execute the display ptp statistics command on the PTP member device for which this notification is generated to identify whether the number of the received messages is increasing.

  - If the number is increasing, the timeout is caused by a long link delay. Locate the reason causing the long link delay.

  - If the number is not increasing, execute the display ptp statistics command on the master device to identify whether the number of sent messages is increasing.

If the number is increasing, a link failure caused the packet loss. You need to fix the issue to recover the link.

If the number is not increasing, go to step 2.

2.If the issue persists, collect alarm information and configuration data, and then contact H3C Support for help.
