TWAMP_1.3.6.1.4.1.2011.5.25.333.1.4.1 hwTwampTwoWayLossRatioExceed

Trap Buffer Description

The two-way loss ratio of the TWAMP test instance exceeded the upper threshold in the 1-minute statistics period. (Test SessionId=[sessionId], Value=[Value], UpperLimitThreshold=[UpperLimitThreshold], LowerLimitThreshold=[LowerLimitThreshold], Sender IP=[sender-address], Reflector IP=[reflector-address], Sender Port=[sender-port], Reflector Port=[reflector-port], VPN Instance=[vpn-name])

The two-way packet loss rate of a TWAMP test instance exceeded the threshold in a 1-minute measurement period.

Impact on the System

A few packets are lost on the network.

Possible Causes

Cause 1: A bit error occurred on the network.
Cause 2: The network bandwidth usage reached or exceeded the preset bandwidth threshold.

Procedure

Cause 1: A bit error occurred on the network.

1. Check whether a bit error occurred.

If yes, find out the cause of the bit error and clear the bit error.
If not, go to Step 2.

2. Collect alarm and configuration information, and contact technical support personnel.

Cause 2: The network bandwidth usage has reached or exceeded the preset bandwidth.

1. Check whether the network bandwidth usage reached or exceeded the preset bandwidth threshold.

If yes, expand the capacity.
If not, go to Step 2.

2. Collect alarm and configuration information, and contact technical support engineers.
