Chapter 1 General Troubleshooting

Troubleshooting Ethernet Circuit Paths With Loopbacks

The entire circuit path has now passed its comprehensive series of loopback tests. This circuit qualifies

to carry live traffic.

Step 5 If the test set indicates a faulty circuit, the problem might be a faulty card.

Step 6 Complete the “Test the Ethernet Card” procedure on page 1-50.

Test the Ethernet Card

Step 1 Complete the “Physically Replace a Card” procedure on page 2-163 for the suspected bad card and

replace it with a known-good card.

Caution Removing a card that currently carries traffic on one or more ports can cause a traffic hit. To avoid this,

perform an external switch if a switch has not already occurred. Refer to the procedures in the

“2.10.1 Protection Switching, Lock Initiation, and Clearing” section on page 2-156. For more

information, refer to the “Maintain the Node” chapter in the Cisco ONS 15310-CL and

Cisco ONS 15310-MA Procedure Guide.

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

Step 3 If the test set indicates a good circuit, the problem was probably the defective card. Return the defective

card to Cisco through the RMA process. Contact Cisco Technical Support (1-800-553-2447).

Step 4 Complete the “Physically Replace a Card” procedure on page 2-163 for the defective card.

Step 5 Clear the terminal loopback on the port:

a. Double-click the source-node CE100T-8 card with the terminal loopback.

b. Click the Maintenance > Loopback tabs.

c. Select None from the Loopback Type column for the port being tested.

d. Select the appropriate state (IS; OOS,DSBLD; OOS,MT) in the Admin State column for the port

being tested.

e. Click Apply.

f. Click Yes in the confirmation dialog box.

Step 6 Clear the terminal loopback circuit:

a. Click the Circuits tab.

b. Choose the loopback circuit being tested.

c. Click Delete.

d. Click Yes in the Delete Circuits dialog box. Do not check any check boxes.

The entire circuit path has now passed its comprehensive series of loopback tests. This circuit qualifies

to carry live traffic.
