Network Test Procedures
Procedure: Retest the Original Destination XTC Card
Step 1
Perform a side switch of the XTC cards to make the original card the active card.
Note
After the active XTC goes into standby, the original standby slot becomes active. This
causes the ACT/STBY LED to become green on the former standby card.
Step 2
Resend test-set traffic on the loopback circuit. The test-set traffic routes through the original XTC card.
Step 3
If the test set indicates a faulty circuit, the problem is probably the defective card.
a.
Return the defective card to Cisco through the returned materials authorization (RMA) process. Call
the Cisco Technical Assistance Center (TAC) at 1-877-323-7368 to open an RMA case.
b.
Make sure the defective XTC card is replaced.
c.
Clear the loopback circuit before testing the next segment of the network circuit path.
d.
Proceed to the
“Perform a Terminal Loopback on a Destination XTC Card” procedure on
.
Step 4
If the test set indicates a good circuit, the XTC card may have had a temporary problem that was cleared
by the side switch.
a.
Clear the loopback circuit before testing the next segment of the network circuit path.
b.
Proceed to the
“Perform a Terminal Loopback on a Destination XTC Card” procedure on
.
12.10.4 Perform a Terminal Loopback on a Destination XTC Card
This test is a terminal loopback performed on the fourth line card in the circuit. In the following example,
the XTC card in the destination node is tested. First, create a bidirectional circuit that starts on the source
node DS-N port and terminates on the destination node DS-N port, then proceed with the terminal
loopback test. Completing a successful terminal loopback to a destination node XTC card port verifies
that the circuit is good up to the destination XTC.

Caution
Performing a loopback on an in-service circuit is service-affecting.
