Chapter 2 Alarm Troubleshooting

Alarm Procedures

Clear the APSIMP Alarm

Step 1 Check the configuration of the other node in the 1+1 protection group. If the far end is not configured

for 1+1 protection, create the group. For procedures, refer to the “Turn Up Node” chapter in the

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

Step 2 If the other end of the group is properly configured or the alarm does not clear after you have provisioned

the group correctly, verify that the working ports and protect ports are cabled correctly.

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

or ONS 15310-MA system.

Step 3 Ensure that both protect ports are configured for SONET.

Step 4 If the alarm 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).

2.7.13 APS-INV-PRIM

Default Severity: Minor (MN), Non-Service-Affecting (NSA)

SONET Logical Object: OCN

The Optimized 1+1 APS Primary Facility condition occurs on OC-N ports in an optimized 1+1

protection system if the incoming primary section header does not indicate whether it is primary or

secondary.

Note APS-INV-PRIM is an informational condition and does not require troubleshooting. If the APS switch

is related to other alarms, troubleshoot these alarms as necessary using the procedures in this chapter.

2.7.14 APSMM

Default Severity: Minor (MN), Non-Service-Affecting (NSA)

SONET Logical Object: OCN

An APS Mode Mismatch failure alarm occurs on OC-3 ports when there is a mismatch of the protection

switching schemes at the two ends of the span, such as being bidirectional at one end and unidirectional

at the other. Each end of a span must be provisioned the same way: bidirectional and bidirectional or

unidirectional and unidirectional.

If one end is provisioned for 1+1 protection switching and the other is provisioned for UPSR switching,

an APSMM alarm occurs on the ONS 15310-CL or ONS 15310-MA that is provisioned for 1+1

protection switching.
