Step 1 In the CTC Circuits window, choose a circuit that passes through the target node and click Edit.
Step 2 In the Edit Circuits window, check Show Detailed Map.
Verify that the VC high-order path and VC low-order path mapping on the node's east and west ports are
Step 3
the same. For example, if a circuit mapping on the west port s5/p1-1/S1 (Slot 5, Port 1-1, VC3), verify
that the mapping is VC3 on the east port. If the circuit appears different VC high-order paths and/or VC
low-order paths on the east and west ports, write down the name of the circuit.
Repeat Steps
