EOAM_Y1731_1.3.6.1.4.1.2011.5.25.136.1.6.23 hwCfmVlanOnewayDelay

Description

EOAM_Y1731/4/VLAN_1DM_EXCEED_THRESHOLD:OID [OID] The result of one-way delay-measure exceeded the threshold. (MdIndex=[GAUGE], MaIndex=[GAUGE], RemoteMacAddress=[OPAQUE], Timestamp=[TIMETICK], DelayValue=[GAUGE], ThresholdValue=[GAUGE])

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.

Parameters

Name Meaning

oid

Indicates the MIB object ID of the alarm.

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

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. Run the trace mac-8021ag command to check whether there is a long delay on the link or device on the network.

    • 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.
