NTP- D329 Create a J0 Section Trace
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.
