DLP-H167 Clear a Path Protection Force Switch
Step 1
From the View menu, choose
Go to Network View
.
Step 2
Right-click the span where you want to clear the switch. Choose
Circuits
from the shortcut menu.
Step 3
In the Circuits on Span dialog box, choose
CLEAR
to remove the switch. Click
Apply
.
Step 4
In the Confirm Path Protection Switch dialog box, click
Yes
.
Step 5
In the Protection Switch Result dialog box, click
OK
.
In the Circuits on Span window, the Switch State for all path protection circuits is CLEAR.
Step 6
Return to your originating procedure (NTP).
DLP-H168 Verify Pass-Through Circuits
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
.
Step 3
Verify that the VC high-order path and VC low-order path mapping on the node’s east and west ports are
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.
Step 4
Repeat Steps
through
for each circuit displayed in the Circuits tab.
Delete and recreate each circuit recorded in Step
that entered/exited the node on different VC
high-order paths. To delete the circuit, complete the
“DLP-H115 Delete Circuits” task on page 17-19
To create circuits, complete the appropriate procedures in
Chapter 5, “Create Circuits and VC Low-order
Purpose
