Chapter 1 General Troubleshooting

Troubleshooting Ethernet Circuit Paths With Loopbacks

Use appropriate cabling to attach the Tx and Rx terminals of the test set to the port you are testing. The

Tx and Rx terminals connect to the same port.

Step 2 Adjust the test set accordingly. (Refer to manufacturer instructions for test-set use.)

Step 3 In CTC node view, double-click the CE100T-8 card to display the card view.

Step 4 Click the Maintenance > Loopback tabs.

Step 5 Choose OOS,MT from the Admin State column for the port being tested. If this is a multiport card,

select the appropriate row for the desired port.

Step 6 Choose Facility from the Loopback Type column for the port being tested. If this is a multiport card,

select the appropriate row for the desired port.

Step 7 Click Apply.

Step 8 Click Ye s in the confirmation dialog box.

Note It is normal for the “LPKTERMINAL (CE100T, CEMR)” condition on page 2-111 to appear

during loopback setup. The condition clears when you remove the loopback.

Step 9 Complete the “Test and Clear the Facility Loopback Circuit” procedure on page 1-32.

Test and Clear the Facility Loopback Circuit

Step 1 If the test set is not already sending traffic, send test traffic on the loopback circuit.

Step 2 Examine the traffic received by the test set. Look for errors or any other signal information that the test

set is capable of indicating.

Step 3 If the test set indicates a good circuit, no further testing is necessary with the facility loopback. Clear the

facility loopback:

a. Double-click the CE100T-8 card, then 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 4 Complete the “Test the Ethernet Card” procedure on page 1-32.

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.
