Chapter 2 Alarm Troubleshooting
Alarm Procedures
The APS Invalid Mode alarm occurs if a 1+1/LMSP 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 subnetwork connection protection (SNCP) protection does not send the right K2 APS byte
anticipated by a system configured for 1+1/LMSP protection. The 1+1/LMSP 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The alarm is superseded by an APSCM alarm. It is not superseded by an AIS condition. It clears when
the port receives a valid code for 10 ms.
Clear the APSIMP Alarm
Step 1 Check the configuration of the other node in the 1+1/LMSP protection group. If the far end is not
configured for 1+1/LMSP protection, create the group. For procedures, refer to the “Turn Up Node”
chapter in the Cisco ONS15310-MA SDH 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-MA SDH system.
Step 3 Ensure that both protect ports are configured for SDH.
Step 4 If the alarm does not clear, log into the Technical Support Website at
http://www.cisco.com/cisco/web/support/index.html for more information or call Cisco TAC
(1-800-553-2447).
2.7.13 AS-CMD
Default Severity: Not Alarmed (NA), Non-Service-Affecting (NSA)
SDH Logical Objects: BPLANE, CEMR, CE100T, CEMR, E1, DS3, E3, EQPT, ML100T, NE, STM,
PWR
DWDM Logical Objects: PPM, SHELF
The Alarms Suppressed by User Command condition applies to the network element (NE object), a
single card, or a port on a card. It occurs when alarms are suppressed for that object and its subordinate
objects. For example, suppressing alarms on a card also suppresses alarms on its ports.
Note For more information about suppressing alarms, refer to the “Manage Alarms” chapter in the
Cisco ONS15310-MA SDH Procedure Guide.
Clear the AS-CMD Condition
Step 1 For all nodes, in node view, click the Conditions tab.
Step 2 Click Retrieve. If you have already retrieved conditions, look under the Object column and Eqpt Type
column and note what entity the condition is reported against—such as a port, slot, or shelf.
