•
Nodal Diversity Desired—Specifies that node diversity is preferred, but if node diversity is not
possible, CTC creates fiber-diverse paths for the path protection portion of the complete circuit path.
•
Link Diversity Only—Specifies that only fiber-diverse primary and alternate paths for path
protection portions of the complete circuit path are needed. The paths might be node-diverse, but
CTC does not check for node diversity.
Step 3
If you selected Review Route Before Creation, complete the following substeps. If not, continue with
Step 4.

DLP-H166 Initiate a Path Protection Force Switch on a Span
Caution
Traffic is not protected during Force path protection switches.
Step 1
From the View menu, choose
Go to Network View
.
Step 2
Right-click the span where you want to Force switch path protection traffic. Choose
Circuits
from the
shortcut menu.
Step 3
In the Circuits on Span dialog box, choose
FORCE SWITCH AWAY
. 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 circuits is FORCE.
Note
A Force switch request on a span or card causes CTC to raise a FORCED-REQ condition. The
condition clears when you clear the Force switch; it is informational only.
Step 6
Return to your originating procedure (NTP).
Purpose
This task switches all circuits on a path protection span to another span.
