Onsite or remote
Step 1 Click the Circuits tab.
Step 2 Click the circuit you want to edit, then click the Edit button.
Step 3 On the Edit Circuit window, click the UPSR Selectors tab.
Note The UPSR Selectors tab is only available when the circuit is in Active state.
Step 4 Edit the following UPSR selectors, as needed:
•Revert Time—Controls whether traffic reverts to the working path when conditions that diverted it to the protect path are repaired. If you choose Never, traffic does not revert. Choosing a time sets the amount of time that will elapse before traffic reverts to the working path.
•SF Ber Level—Sets the UPSR signal failure BER threshold (STS circuits only).
•SD Ber Level—Sets the UPSR signal degrade BER threshold (STS circuits only).
•PDI-P—When checked, traffic switches if an STS payload defect indication is received (STS circuits only).
•Switch State—Switches circuit traffic between the working and protect paths. The color of the Working Path and Protect Path fields indicates the active path. Normally, the Working Path is green and the Protect Path is purple. If the Protect Path is green, working traffic has switched to the Protect Path.
CLEAR—Removes a previously-set switch command.
LOCKOUT OF PROTECT—Prevents traffic from switching to the protect circuit path under any circumstances. Of all switch states, LOCKOUT has the highest priority.
FORCE TO WORKING—Forces traffic to switch to the working circuit path, even if the path has signal degrade (SD) or signal failure (SF) conditions. FORCE switch states have a higher priority than MANUAL switch.
FORCE TO PROTECT—Forces traffic to switch to the protect circuit path, even if the path has signal degrade (SD) or signal failure (SF) conditions. FORCE switch states have a higher priority than MANUAL switch.
MANUAL TO WORKING—Switches traffic to the working circuit path if the path has an error rate less than the signal degrade.
MANUAL TO PROTECT—Switches traffic to the protect circuit path if the path has an error rate less than the signal degrade.
Caution The FORCE and LOCKOUT commands override normal protection switching mechanisms. Applying these commands incorrectly can cause traffic outages.
Step 5 Click Apply, then check that the selector switches are displayed as you expect.

Note This procedure assumes you are setting up path trace on a bidirectional circuit, and you will set transmit strings at the circuit source and destination.
Step 1 Click the Circuits tab.
Step 2 For the STS circuit you want to monitor, verify that the source and destination ports are on a card that can transmit and receive the path trace string. See Table 9-1 for a list of cards.
If neither port is on a transmit/receive card, you will not be able to complete this procedure. If one port is on a transmit/receive card and the other on a receive-only card, you can set up the transmit string at the transmit/receive port and the receive string at the receive-only port, but you will not be able to transmit in both directions.
Step 3 Choose the STS circuit you want to trace, then click Edit.
Step 4 On the Edit Circuit window, click the Show Detailed Map box at the bottom of the window. A detailed map of the source and destination ports is displayed.
Step 5 Provision the circuit source transmit string:
a. On the detailed circuit map right-click the circuit source port (square on the left or right of the source node icon) and choose Edit Path Trace (Port) from the shortcut menu. Figure 9-3 shows an example.
Figure 9-3 Selecting the Edit Path Trace option
b. In the New Transmit String field, enter the circuit source transmit string. Enter a string that makes the source port easy to identify, such as node IP address, node name, circuit name, or another string. If the New Transmit String field is left blank, the J1 transmits a string of null characters.
c. Click Apply, then click Close.
Step 6 Provision the circuit destination transmit string:
a. On the Edit Circuit window (with Show Detailed Map chosen, see Figure 9-3) right-click the circuit destination port and choose Edit Path Trace (Port) from the shortcut menu.
b. In the New Transmit String field, enter the string that you want the circuit destination to transmit. Enter a string that makes the destination port easy to identify, such as node IP address, node name, circuit name, or another string. If the New Transmit String field is left blank, the J1 transmits a string of null characters.
c. Click Apply.
Step 7 Provision the circuit destination expected string:
a. On the Circuit Path Trace window, enable the path trace expected string by choosing Auto or Manual from the Path Trace Mode drop-down menu:
–Auto—the first string received from the source port is the baseline. An alarm is raised when a string that differs from the baseline is received.
–Manual—the string entered in Current Expected String is the baseline. An alarm is raised when a string that differs from the Current Expected String is received.
b. If you set Path Trace Mode to Manual, enter the string that the circuit destination should receive from the circuit source in the New Expected String field. If you set Path Trace Mode to Auto, skip this step.
c. Click the Disable AIS on TIM-P checkbox if you want to suppress the Alarm Indication Signal when the STS Path Trace Identifier Mismatch Path (TIM-P) alarm is displayed. Refer to the Cisco ONS 15454 Troubleshooting Guide for descriptions of alarms and conditions.
Note RDI (Remote Defect Indicator) conditions on TIM-P are not generated in this release.
d. Click Apply, then click Close.
Step 8 Provision the circuit source expected string:
a. On the Edit Circuit window (with Show Detailed Map chosen, see Figure 9-3) right-click the circuit source port and choose Edit Path Trace (Port) from the shortcut menu.
b. On the Circuit Path Trace window, enable the path trace expected string by choosing Auto or Manual from the Path Trace Mode drop-down menu:
–Auto—Uses the first string received from port at the other end as the baseline string. An alarm is raised when a string that differs from the baseline is received.
–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.
c. If you set Path Trace Mode to Manual, enter the string that the circuit source should receive from the circuit destination in the New Expected String field. If you set Path Trace Mode to Auto, skip this step.
d. Click the Disable AIS on TIM-P checkbox if you want to suppress the Alarm Indication Signal when the STS Path Trace Identifier Mismatch Path (TIM-P) alarm is displayed. Refer to the Cisco ONS 15454 Troubleshooting Guide for descriptions of alarms and conditions.
e. Click Apply.
Step 9 After you set up the path trace, the received string is displayed in the Received box on the path trace setup window. Figure 9-4 shows an example. The following options are available:
•Click Switch Mode to toggle between ASCII and hexadecimal display.
•Click the Reset button to reread values from the port.
•Click Default to return to the path trace default settings (Path Trace Mode is set to Off and the New Transmit and New Expected Strings are null).
Caution Clicking Default will generate alarms if the port on the other end is provisioned with a different string.
The Expect and Receive strings are updated every few seconds as long as Path Trace Mode is set to Auto or Manual.
Step 10 Click Close.
When you display the detailed circuit window, path trace is indicated by an M (manual path trace) or an A (automatic path trace) at the circuit source and destination ports. Figure 9-5 shows an example.

DLP-137 Provision Path Trace on OC-N Ports
Purpose
Use this task to monitor a path trace on OC-N ports within the circuit path.
Tools/Equipment
ONS 15454 cards capable of receiving path trace must be installed at the OC-N circuit ports. See Table 9-1.
Prerequisite Procedures
DLP-136 Provision Path Trace on Circuit Source and Destination Ports.
Required/As Needed
As needed
Onsite/Remote
Onsite or remote
Step 1 Log into the node on the network where path trace was provisioned on the circuit source and destination ports. See the "DLP-60 Log into CTC" task for instructions.
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 On the Edit Circuit window, click the Show Detailed Map box at the bottom of the window. A detailed circuit graphic showing source and destination ports is displayed.
Step 5 On the detailed circuit map right-click the circuit OC-N port (square on the left or right of the source node icon) and choose Edit Path Trace (Port) from the shortcut menu.
Note The OC-N port must be on a receive-only card listed in Table 9-1. If not, the Edit Path Trace (Port) menu item will not display.
Step 6 On the Circuit Path Trace window, enable the path trace expected string by choosing Auto or Manual from the Path Trace Mode drop-down menu:
•Auto—Uses the first string received from port at the other end as the baseline string. An alarm is raised when a string that differs from the baseline is received. For OC-N 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 Path Trace Mode 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 Path Trace Mode to Auto, skip this step.
Step 8 Click the Disable AIS on TIM-P checkbox if you want to suppress the Alarm Indication Signal when the STS Path Trace Identifier Mismatch Path (TIM-P) alarm is displayed. Refer to the Cisco ONS 15454 Troubleshooting Guide for descriptions of alarms and conditions.
Step 9 Click Apply, then click Close.
Step 10 Return to your originating procedure (NTP).
