Traffic maintenance
Provisioning a path trace
...................................................................................................................................................................................................................................
When to use
A path trace can be set at any time. Path trace provisioning can be done only once,
after provisioning a path, to check whether the path is correctly provisioned. Path trace
can also be used continuously to check if the traffic is delivered to the correct
destination. When provisioning a path trace on a path with traffic on it, take notice of
the precautions.
Related information
Before provisioning a path trace determine the following:
• In which termination point is the path trace inserted and in which termination
points is it monitored?
• Which label is used as path trace?
Other related information:
• If the Trace Identifier Mismatch (TIM) detection is enabled, traffic will be lost
when a mistake in the trace string is made. Upon mismatch, an Alarm Indication
Signal (AIS) is inserted in the downstream signal and Remote Defect Indicator
(RDI) is inserted in the upstream signal (RDI is only inserted when directionality is
set to bidirectional).
• If the identifier is shorter than 15 characters, the rest is filled with zeroes.
Therefore the hexadecimal version of a blank identifier will be shown as all zeroes,
not blank. Spaces at the end of an identifier will be also hexadecimal zeroes. When
other network element types participate in the path this may not be the same.
Always check the hexadecimal value.

Procedure
The purpose of this procedure is to provision a path trace.
...................................................................................................................................................................................................
Determine where the termination points of the path are located. If a specific string
1
(API) is used determine the content of the label.
...................................................................................................................................................................................................
Select Provisioning -> Transport -> Termination Point.
2
Result:
...................................................................................................................................................................................................
Select the type of the termination point for which the path trace must be provisioned
3
and fill in its location. Click
