Chapter 1 General Troubleshooting

Troubleshooting Ethernet Circuit Paths With Loopbacks

Step 4 Confirm that the newly created circuit appears on the Circuits tab list as a two-way circuit.

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

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

Step 5 Create the terminal loopback on the destination port being tested:

a. Go to the node view of the destination node:

• Choose View > Go To Other Node from the menu bar.

• Choose the node from the drop-down list in the Select Node dialog box and click OK.

b. In node view, double-click the CE100T-8 card that requires the loopback.

c. Click the Maintenance > Loopback tabs.

d. Select OOS,MT from the Admin State column. If this is a multiport card, select the row appropriate

for the desired port.

e. Select Termin al from the Loopback Type column. If this is a multiport card, select the row

appropriate for the desired port.

f. Click Apply.

g. Click Yes in the confirmation dialog box.

Step 6 Complete the “Test and Clear the Ethernet Terminal Loopback Circuit” procedure on page 1-49.

Test and Clear the Ethernet Terminal Loopback Circuit

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

Step 2 Examine the test traffic being 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 on the loopback circuit. Clear the

terminal loopback from the port:

a. Double-click the intermediate-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 4 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.
