TWAMP/2/TWAMP_TWOWAY_LOSS_active

Message

TWAMP/2/TWAMP_TWOWAY_LOSS_active: 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])

Description

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

Parameters

Parameter Name	Parameter Meaning
sessionId	TWAMP Light test session ID.
Value	Packet loss rate.
UpperLimitThreshold	The Loss trigger-alarm threshold value.
LowerLimitThreshold	The clear-alarm Loss threshold value.
sender-address	IP address of the sender.
reflector-address	IP address of the reflector.
sender-port	Port number of the sender.
reflector-port	Port number of the reflector.
vpn-name	Indicates the VPN instance name.

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.
