Chapter 1 General Troubleshooting

Restoring the Database and Default Settings

Select the appropriate state (IS, OOS, or OOS_AINS) in the State column for the port being tested.

Click the Apply button.

Click the Yes button in the Confirmation Dialog box. d. Clear the terminal loopback circuit:

Click the Circuits tab.

Choose the loopback circuit being tested.

Click the Delete button.

Click the Yes button in the Delete Circuits dialog box.

Step 4 The entire OC-N circuit path has now passed its comprehensive series of loopback tests. This circuit qualifies to carry live traffic.

1.4 Restoring the Database and Default Settings

This section contains troubleshooting procedures for node operation errors that require restoration of software data or the default node setup.

1.4.1 Restore the Node Database

Symptom: One or more node(s) are not functioning properly or have incorrect data.

Table 1-1 on page 1-41describes the potential cause of the symptom and the solution.

Table 1-1 Restore the Node Database

Possible Problem

Solution

 

 

Incorrect or corrupted

Perform a Restore the Database procedure. Refer to the “Restore the

node database.

Database” procedure on page 1-41.

 

 

Procedure: Restore the Database

Note When you restore the database, the following parameters are not backed up and restored: node name, IP address, mask and gateway, and IIOP port. If you change the node name and then restore a backed up database with a different node name, the circuits map to the new renamed node. Cisco recommends keeping a record of the old and new node names.

Caution E10/100-4 cards lose traffic for approximately 90 seconds when an ONS 15327 database is restored. Traffic is lost during the period of spanning-tree reconvergence. The CARLOSS alarm appears and clears during this period.
