Parameters

Name Meaning

oid

Indicates the MIB object ID of the alarm.

TestInstanceId

IP FPM instance ID.

AchId

Atomic closed hop ID. Hop-by-Hop performance statistics collection does not support to generate an alarm based on ACH.

IpfpmMcpSeqNoHigh

32 most significant bits of the statistical period ID.

IpfpmMcpSeqNoLow

32 least significant bits of the statistical period ID.

FlowType

Target flow type.

ForwardPktLossRatio

Packet loss rate for the forward target flow.

BackwardPktLossRatio

Packet loss rate for the backward target flow.

InstanceDescription

IP FPM instance description.

Impact on the System

The packet loss ratios in five consecutive measurement intervals exceed the alarm threshold. The network transmission quality is poor.

Possible Causes

  1. The network bandwidth was insufficient because of abnormal traffic.
  2. The physical link was unstable.

Procedure

  1. Check whether abnormal traffic existed on the network when the trap was generated.

    • If abnormal traffic existed on the network, go to Step 2.
    • If no abnormal traffic existed on the network, go to Step 3.

  2. Check whether the abnormal traffic was caused by misoperations.

    • If the abnormal traffic was caused by misoperations, go to Step 3.
    • If the abnormal traffic was not caused by misoperations, go to Step 6.

  3. Delete the misoperation configurations and check whether the trap persists.

    • If the trap persists, go to Step 4.
    • If the trap is cleared, go to Step 7.

  4. Check whether the link status was stable when the trap was generated.

    • If the link status was stable, go to Step 6.
    • If the link status was unstable, go to Step 5.

  5. Check the problem that caused the unstable link status, resolve the problem, and check whether the trap persists.

    • If the trap persists, go to Step 6.
    • If the trap is cleared, go to Step 7.

  6. Collect alarm information and configuration information, and then contact technical support personnel.
  7. End.
