Chapter 2 Alarm Troubleshooting
Alarm Procedures
Clear the APSMM Alarm
Step 1 For the reporting system, in node view verify the protection scheme provisioning by completing the
following steps:
a. In node view, click the Provisioning > Protection tabs.
b. Click the 1+1 protection group configured for the OC-3 or OC-12 ports.
The chosen protection group is the protection group that is optically connected (with data
communication channel [DCC] connectivity) to the far end.
Step 2 Click Edit.
Record whether the Bidirectional Switching check box is checked.
Step 3 Click OK in the Edit Protection Group dialog box.
Step 4 Log into the far-end node and verify that the OC-3 or OC-12 port 1+1 protection group is provisioned.
Step 5 Verify that the Bidirectional Switching check box matches the checked or unchecked condition of the
box recorded in Step 1. If not, change it to match.
Step 6 Click Apply.
Step 7 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).
