Chapter 1 General Troubleshooting
Troubleshooting Ethernet Circuit Paths With Loopbacks
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.
Step 5 Complete the “Test the Ethernet Card” procedure on page 1-47.
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 one.
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 installed.
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 faulty card.
Step 5 Clear the facility loopback on the port:
a. Double-click the CE100T-8 card and click the Maintenance > Loopback tabs.
b. Choose None from the Loopback Type column for the port being tested.
c. Choose the appropriate state (IS; OOS,DSBLD; OOS,MT) from the Admin State column for the port
being tested.
d. Click Apply.
e. Click Yes in the confirmation dialog box.
Step 6 Clear the facility 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.
Step 7 Complete the “1.6.7 Perform a Terminal Loopback on a Destination-Node Ethernet Port” procedure on
page 1-48.
