2.8 Common Procedures in Alarm Troubleshooting

This section gives common procedures that are frequently used when troubleshooting alarms. For more information about ring or node traffic switching operations, refer to the Cisco ONS 15327 Procedure Guide.

Procedure: Identify a Ring ID or Node ID Number

Step 1 Log into a node on the network. If you are already logged in, go to Step 2.

Step 2 In node view, click View > Go to Network View.

Step 3 Click the Provisioning > BLSR tabs.

From the Ring ID column, record the Ring ID, or in the nodes column, record the Node IDs in the BLSR. The Node IDs are the numbers in parentheses next to the node name.

Procedure: Change a Ring ID Number

Step 1 Log into a node on the network. If you are already logged in, go to Step 2.

Step 2 In node view, click View > Go to Network View.

Step 3 Click the Provisioning > BLSR tabs.
