DLP-H122 Provision Path Trace on STM-M Ports
Step 1 From the View menu, choose Go to Other Node . In the Select Node dialog box, choose the node where
path trace was provisioned on the circuit source and destination ports.
Step 2
In node view, click Circuits .
Step 3 Choose the VC high-order path circuit that has path trace provisioned on the source and destination
ports, then click
Edit .
Step 4
In the Edit Circuit window, check the Show Detailed Map check box at the bottom of the window. A
detailed circuit graphic showing source and destination ports appears.
Step 5
In the detailed circuit map, right-click the circuit STM-M port (the square on the left or right of the
source node icon) and choose
Edit Path Trace from the shortcut menu.
Step 6
In the Circuit Path Trace window, enable the path trace expected string by choosing Auto or Manual
from the Path Trace Mode drop-down list:
• Auto—Uses the first string received from the port at the other end as the baseline string. An alarm
is raised when a string that differs from the baseline is received. For STM-M ports, Auto is
recommended, since Manual mode requires you to trace the circuit on the Edit Circuit window to
determine whether the port is the source or destination path.
•
Manual—Uses the Current Expected String field as the baseline string. An alarm is raised when a
string that differs from the Current Expected String is received.
Step 7 If you set the Path Trace Mode field to Manual, enter the string that the STM-M port should receive in
the New Expected String field. To do this, trace the circuit path on the detailed circuit window to
determine whether the port is in the circuit source or destination path, then set the New Expected String
field to the string transmitted by the circuit source or destination. If you set the Path Trace Mode field
to Auto, skip this step.
Step 8
Click Apply , then click Close .
Step 9
Return to your originating procedure (NTP).
Purpose This task monitors a path trace on STM-M ports within the circuit path.
Tools/Equipment The STM-M ports you want to monitor must be on STM-M cards capable
of receiving path trace. See
Table 17-6 on page 17-27 .
