DLP- E181 Provision Path Trace on OC-N Ports
The expect and receive strings are updated every few seconds if the Path Trace Mode field is set to Auto
or Manual.
Step 11 Click Close.
The detailed circuit window indicates path trace with an M (manual path trace) or an A (automatic path
trace) at the circuit source and destination ports.
Step 12 Return to your originating procedure (NTP).
DLP-E181 Provision Path Trace on OC-N 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 Click Circuits.
Step 3 Choose the STS circuit that has path trace provisioned on the source and destination ports, then click
Edit.
Step 4 In the Edit Circuit window, click 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 OC-N port (the square on the left or right of the source
node icon) and choose Edit Path Trace from the shortcut menu.
Note The OC-N port must be on a receive-only card listed in Table17-1 on page 17-61. If not, the
Edit Path Trace menu item will not appear.
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 path trace end as the current expected
string. An alarm is raised when a string that differs from the baseline is received. For OC-N ports,
Auto is recommended because 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.
Purpose This task monitors a path trace on OC-N ports within the circuit path.
Tools/Equipment The OC-N ports you want to monitor must be on OC-N cards capable of
receiving path trace. See Table17-1 on page 17-61.
