Chapter 1 General Troubleshooting

Identify Points of Failure on an OC-N Circuit Path

Procedure: Test the OC-N Card

Step 1 Replace the suspect card with a card known to be good. See the “Physically Replace a Card” procedure on page 2-130for details.

Step 2 Resend test traffic on the loopback circuit with a good card installed.

Step 3 If the test set indicates a good circuit, the problem is probably the defective card:

a.Return the defective card to Cisco through the returned materials authorization (RMA) process. Contact the Cisco TAC.

b.Replace the faulty card. See the “Physically Replace a Card” procedure on page 2-130for details.

c.Clear the facility loopback:

Click the Maintenance > Loopback tabs.

Choose None from the Loopback Type column for the port being tested.

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

Click the Apply button.

Click the Yes button in the Confirmation Dialog box.

d.Clear the facility 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 Proceed to the “1.3.5 Perform a Terminal Loopback on an Intermediate-NodeOC-N Port” section on page 1-32.

1.3.5 Perform a Terminal Loopback on an Intermediate-Node OC-N Port

The terminal loopback test is performed on the node destination port in the circuit, in this example, the destination OC-N port in the intermediate node. First, create a bidirectional circuit that starts on the node source OC-N port and loops back on the node destination OC-N port. Then proceed with the terminal loopback test. Completing a successful terminal loopback to a node destination OC-N port verifies that the circuit is good up to the destination OC-N port. Figure 1-16 on page 1-33shows an example of a terminal loopback on an intermediate node destination OC-N port.
