EOAM-Y1731/4/VLAN_1DM_EXCEED_THRESHOLD_active: 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.
| Parameter Name | Parameter Meaning |
|---|---|
|
MdIndex |
Index of the MD where a one-way frame delay alarm is generated |
|
MaIndex |
Index of the MA where a one-way frame delay alarm is generated |
|
RemoteMacAddress |
Source MAC address contained in the 1DM frame received by the local end from the remote end |
|
Timestamp |
Timestamp indicating the time when a one-way frame delay alarm is generated |
|
DelayValue |
Delay when a one-way frame delay alarm is generated |
|
ThresholdValue |
An alarm threshold for one-way frame delay measurement |
|
DelayValueHigh |
32 most significant bits |
|
DelayValueLow |
32 least significant bits |
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.
1. Check whether the clocks of the transmitting device and the receiving device are synchronized.
2. Perform clock synchronization between the two devices. Then, check whether the alarm is cleared.
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.
4. Troubleshoot the fault of a long delay. Then, check whether the alarm is cleared.
5. Collect alarm information and configuration information, and then contact technical support personnel.
6. End.
