EOAM-Y1731_1.3.6.1.4.1.2011.5.25.136.1.6.23 hwCfmVlanOnewayDelay

Trap Buffer Description

The result of one-way delay-measure exceeded the threshold. (MdIndex=[MdIndex], MaIndex=[MaIndex], RemoteMacAddress=[RemoteMacAddress], Timestamp=[Timestamp], DelayValue=[DelayValue], ThresholdValue=[ThresholdValue], DelayValueHigh=[DelayValueHigh], DelayValueLow=[DelayValueLow])

In the VLAN networking where one-way frame delay measurement was configured and an expected alarm threshold was set, if the network delay exceeded the alarm threshold, an alarm was generated.

Impact on the System

Services will not be affected.

Possible Causes

The device was enabled with one-way frame delay measurement and was configured with an alarm threshold, and the delay in unidirectional frame transmission exceeded the alarm threshold.

Procedure

1. Check whether the clocks of the transmitting device and the receiving device are synchronized.

If the clocks of the two devices are synchronized, go to Step 3.
If the clocks of the two devices are not synchronized, go to Step 2.

2. Perform clock synchronization between the two devices. Then, check whether the alarm is cleared.

If the alarm is cleared, go to Step 6.
If the alarm is not cleared, go to Step 5.

3. Use the trace function defined in 801.1ag to check whether there is a long delay in frame transmission on a link or a device.

If there is a long delay, go to Step 4.
If there is no long delay, go to Step 5.

4. Troubleshoot the fault of a long delay. Then, check whether the alarm is cleared.

If the alarm is cleared, go to Step 6.
If the alarm is not cleared, go to Step 5.

5. Collect alarm information and configuration information, and then contact technical support personnel.

6. End.
