Step 1 Complete the "DLP-D60 Log into CTC" task at a node on the network where you will create the section trace. If you are already logged in, continue with Step 2.

Step 2 In node view, double-click the MRC-12 or STM64-XFP card.

Step 3 Click the Provisioning > Line > Section Trace tabs.

Step 4 From the Port drop-down list, choose the port for the section trace.

Step 5 From the Trace Mode drop-down list, enable the section trace expected string by choosing Auto or Manual:

Auto—The first string received from the source port is automatically provisioned as the current expected string. An alarm is raised when a string that differs from the baseline is received.

Manual—The string entered in the Current Expected String field is the baseline. An alarm is raised when a string that differs from the Current Expected String is received.

Step 6 In the Section Trace String Size area, click 1 byte, 16 byte, or 64 byte. In the New Transmit String field, enter the string that you want to transmit. Enter a string that makes the destination port easy to identify, such as the node IP address, node name, or another string. If the New Transmit String field is left blank, the J0 transmits a string of null characters.

Step 7 If you set the Section Trace Mode field to Manual, enter the string that the destination port should receive from the source port in the New Expected String field. If you set Section Trace Mode to Auto, skip this step.

Step 8 Click the Disable AIS and RDI if TIM-P is detected check box if you want to suppress the alarm indication signal (AIS) and remote defect indication (RDI) when the STS Section Trace Identifier Mismatch Path (TIM-P) alarm appears. Refer to the Cisco ONS 15454 SDH Troubleshooting Guide for descriptions of alarms and conditions.

Step 9 Click Apply.

Step 10 After you set up the section trace, the received string appears in the Received field. The following options are available:

Click Hex Mode to display section trace in hexadecimal format. The button name changes to ASCII Mode. Click it to return the section trace to ASCII format.

Click the Reset button to reread values from the port.

Click Default to return to the section trace default settings (Section 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 if the Section Trace Mode field is set to Auto or Manual.

Stop. You have completed this procedure.


NTP-D79 Create a J1 or J2 Path Trace

Purpose

This procedure creates a repeated, fixed-length string of characters used to monitor changes to circuit traffic.

Tools/Equipment

ONS 15454 SDH cards capable of transmitting and/or receiving path trace must be installed. See Table 19-5 for a list of J1 path trace cards. See Table 20-30 for a list of J2 path trace cards.

Prerequisite Procedures

J1 path trace can be provisioned on VC3 and VC4 circuits. J2 path trace can be provisioned on VC12 circuits. See Chapter 6 "Create Circuits and Low-Order Tunnels," for circuit creation procedures.
