DLP-A137 Provision Path Trace on OC-N Ports
DLP-A137 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 Table 19-3 on page 19-47. 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.
Step 7 If you set the Path Trace Mode field to Manual, enter the string that the OC-N 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 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 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 Table 19-3 on page 19-47.
