Chapter 1 General Troubleshooting

Troubleshooting Ethernet Circuit Paths With Loopbacks

h. Click Next.

i. In the Circuit Creation destination dialog box, use the same Node, card Slot, Port, and STS (or VT)

used for the source dialog box.

j. Click Next.

k. In the Circuit Creation circuit routing preferences dialog box, leave all defaults. Click Finish.

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 2.7.163 LPKTERMINAL (CE100T, CEMR) to appear during a loopback

setup. The condition clears when you remove the loopback.

Step 5 Create the facility 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 Facility 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 Facility Loopback Circuit” procedure on page 1-46.

Test and Clear the Ethernet 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 from 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 4 Clear the facility loopback circuit:

a. Click the Circuits tab.
