Apsimp - Cisco NCS 2000 series Troubleshooting Manual

APSIMP

2. If the fibers are correctly connected, verify that the protection-card channel fibers are physically connected
directly to the adjoining node protection-card channel fibers.
DETAILED STEPS
Step 1 Verify that the working-card channel fibers are physically connected directly to the adjoining node working-card channel
fibers.
Step 2 If the fibers are correctly connected, verify that the protection-card channel fibers are physically connected directly to
the adjoining node protection-card channel fibers.
If the condition does not clear, log into the Technical Support Website at
for more information or call Cisco TAC (1 800 553-2447).
APSIMP
Default Severity: Minor (MN), Non-Service-Affecting (NSA)
Logical Object: OCN, STMN
The APS Invalid Code alarm occurs if a 1+1 protection group is not properly configured at both nodes to send
or receive the correct APS byte. A node that is either configured for no protection or is configured for path
protection or BLSR protection does not send the right K2 APS byte anticipated by a system configured for
1+1 protection. The 1+1 protect port monitors the incoming K2 APS byte and raises this alarm if it does not
receive the byte.
The alarm is superseded by an APSCM or APSMM alarm, but not by an AIS condition. It clears when the
port receives a valid code for 10 ms.
Clear the APSIMP Alarm
SUMMARY STEPS
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.
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.
3. Ensure that both protect ports are configured for SONET.
