Chapter 1 General Troubleshooting
1.6.6 Perform a Terminal Loopback on a Destination-Node Ethernet Port
Step 2
Adjust the test set accordingly. (Refer to manufacturer instructions for test-set use.)
Step 3 Use CTC to set up the terminal loopback on the test port:
a.
In node view, click the Circuits tab and click Create .
b.
In the Circuit Creation dialog box, choose the type, such as STS, and number, such as 1.
c.
Click Next .
d. In the next Circuit Creation dialog box, give the circuit an easily identifiable name such as
C1C1toC1C6.
e.
Leave the Bidirectional check box checked.
f. Click Next .
g.
In the Circuit Creation source dialog box, select the same Node, card Slot, Port, and STS (or VT)
where the test set is connected.
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 “LPKTERMINAL (CE100T)” condition on page 1-105 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 Terminal 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 1-42 .
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.
