PTP_1.3.6.1.4.1.2011.5.25.187.5.11 hwPTPRingFiberLengthChange

Description

PTP/3/PTPTRAPDFXRINGFIBERLENGTHCHANGE: OID [oid] [integer] The new offset value of the ring-network optical fiber that is connected to [STRING] is [integer1], which is a [integer2] value.

The ring network fiber length was changed.

Attribute

Alarm ID	Alarm Severity	Alarm Type
1.3.6.1.4.1.2011.5.25.187.5.11	minor	equipmentAlarm(6)

Parameters

Name	Meaning
[oid]	Indicates the MIB object ID of the alarm.
integer	Interface index
STRING	Interface name
integer1	New time offset caused by the fiber length change
integer2	Positive and negative values of the new time offset caused by the fiber length change

Impact on the System

The precision of clock synchronization is affected.

Possible Causes

The difference between the time offset caused by the fiber length change and the configured asymmetry correction value exceeded the specified range (± 55 ns).

Procedure

Run the display this command in the interface view to check whether the asymmetry correction value is configured on the interface. That is, whether the ptp asymmetric-correction command configuration exists.
- If yes, go to Step 2.
- If no, go to Step 3.
Run the ptp asymmetric-correction command to reconfigure the asymmetry correction value.
Collect traps, logs, and configurations, and contact technical support personnel.
