Chapter 2 Alarm Troubleshooting

Alarm Procedures

Clear the PDI-P Condition

Step 1 Verify that all circuits terminating in the reporting card are in an active state by completing the following

steps:

a. Click the Circuits tab.

b. Verify that the Status column lists the port as active.

c. If the Status column lists the port as incomplete, wait 10 minutes for the ONS 15310-CL or

ONS 15310-MA to initialize fully. If the incomplete state does not change after full initialization,

log into the Technical Support Website at http://www.cisco.com/techsupport for more information

or call Cisco TAC to report a Service-Affecting (SA) problem (1-800-553-2447).

Step 2 After determining that the port is active, ensure that the signal source to the card reporting the alarm is

working.

Step 3 If traffic is affected, complete the “Delete a Circuit” procedure on page 2-164.

Caution Deleting a circuit can affect existing traffic.

Step 4 Recreate the circuit with the correct circuit size. Refer to the “Create Circuits” chapter in the

Cisco ONS 15310-CL and Cisco ONS 15310-MA Procedure Guide for procedures.

Step 5 If the circuit deletion and re-creation does not clear the condition, verify that there is no problem with

the far-end OC-3 or OC-12 port providing STS payload to the reporting card.

Step 6 If the condition does not clear, confirm that the cross-connect between the OC-3 or OC-12 port and the

reporting port is good.

Step 7 If the condition does not clear, clean the far-end optical fiber according to site practice. If no site practice

exists, complete the procedure in the “Maintain the Node” chapter in the Cisco ONS 15310-CL and

Cisco ONS 15310-MA Procedure Guide.

Caution Always use the supplied electrostatic discharge wristband when working with a powered ONS 15310-CL

or ONS 15310-MA.

Step 8 If the condition does not clear, log into the Technical Support Website at

http://www.cisco.com/techsupport for more information or call Cisco TAC (1-800-553-2447).

2.7.189 PLM-P

Default Severity: Critical (CR), Service-Affecting (SA)

SONET Logical Objects: STSMON, STSTRM

A Payload Label Mismatch Path alarm indicates that signal does not match its label. The condition is

indicated by an invalid C2 byte value in the SONET path overhead.

This alarm can occur on a 15310-CL-CTX, DS1-28/DS3-EC1-3, or DS1-84/DS3-EC1-3 card when it

expects a DS-1 signal but receives a DS-3 signal. The DS-3 signal C2 byte value is 4, so this causes a

label mismatch and a PLM-P alarm.
