DLP-A442 Verify Pass-Through Circuits
DLP-A442 Verify Pass-Through Circuits
Step 1 In the CTC Circuits window, choose a circuit that passes through the node that will be removed and click
Edit.
Step 2 In the Edit Circuits window, check Show Detailed Map.
Step 3 Verify that the STS and VT mapping on the node’s east and west ports are the same. For example, if the
circuit mapping on the west port is s5/p1/S1 (Slot 5, Port 1, STS 1), verify that the mapping is STS 1 on
the east port. If the circuit displays different STSs and/or VTs on the east and west ports, record the name
of the circuit. Figure 21-2 shows a circuit passing through a node (doc-124) on the same STS (STS 2).
Figure 21-2 Verifying Pass-Through STSs
Step 4 Repeat Steps 1 to 3 for each circuit in the Circuits tab.
Step 5 Delete and recreate each circuit recorded in Step 3. To delete the circuit, see the “DLP-A333 Delete
Circuits” task on page 20-21. To create the circuit, see Chapter 6, “Create Circuits and VT Tunnels.”
Step 6 Return to your originating procedure (NTP).
Purpose This task verifies that circuits passing through a node enter and exit the
node on the same STS and/or VT.
