TWAMP/4/TWAMP_TWOWAY_JITTER_active

Message

TWAMP/4/TWAMP_TWOWAY_JITTER_active: The two-way jitter of the TWAMP test instance exceeded the upper threshold in three consecutive test intervals. (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 jitter of a TWAMP test instance exceeded the threshold in three consecutive measurement periods.

Parameters

Parameter Name	Parameter Meaning
sessionId	TWAMP Light test session ID.
Value	Jitter value
UpperLimitThreshold	The jitter trigger-alarm threshold value.
LowerLimitThreshold	The clear-alarm jitter 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: The network bandwidth usage reached or exceeded the preset bandwidth threshold.
Cause 2: The service traversed a large number of NEs.

Procedure

Cause 1: The network bandwidth usage reached or exceeded the preset bandwidth threshold.

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 information and configuration information, and then contact technical support personnel.

Cause 2: The service traversed a large number of NEs.

1. Check whether the service traversed a large number of NEs.

If yes, perform rerouting. Alternatively, delete the original path and establish a new one.
If not, go to step 2.

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