NTP-B105 Add a Path Protection Node
Click the Alarms tab. Verify that no critical or major alarms are present, nor any facility alarms, such as
Step 8
LOS, LOF, AIS-L, SF, and SD. If trouble is indicated (for example, a major alarm exists), resolve the
problem before proceeding. See
Cisco ONS 15327 Troubleshooting Guide.
Step 9 Complete the following steps if the node is on the same subnet as other BLSR nodes, it is not provisioned
as an external network element (see
and a CTC computer will directly connect to the node while other CTC computers are directly connected
to other BLSR nodes. If not, continue with
Click the Provisioning > Network > General tabs. View the IP Address and Net/Subnet Mask
a.
Length fields to verify the node is on the same subnet as other BLSR nodes.
Click the Static Route tab and click Create.
b.
In the Create Static Route dialog box, enter the following settings:
c.
Click OK.
d.
(Optional) Create test circuits, making sure they pass through the path protection line cards, and run test
Step 10
traffic through the node to ensure the cards are functioning properly. See the
Manually Routed Optical Circuit" procedure on page 5-43
procedure on page 5-51
Create the DCC terminations on the new node. See the
Step 11
Terminations" task on page
From the View menu, choose Go to Network View.
Step 12
Complete the
Step 13
away from the span that will be broken to connect to the new node.
Caution Traffic is not protected during a protection switch.
Step 14 Two nodes will connect directly to the new node; remove their fiber connections:
Remove the east fiber connection from the node that will connect to the west port of the new node.
a.
Remove the west fiber connection from the node that will connect to the east port of the new node.
b.
Replace the removed fibers with the fibers that are connected to the new node.
Step 15
Log out of CTC and log back into a node in the network.
Step 16
From the View menu, choose Go to Network View to display the path protection nodes. The new node
Step 17
should appear in the network map. Wait for a few minutes to allow all the nodes to appear.
Click the Circuits tab and wait for all the circuits to appear, including spans. Count the number of
Step 18
incomplete circuits.
In the network view, right-click the new node and choose Update Circuits With New Node from the
Step 19
list of options. Wait for the confirmation dialog box to appear. Verify that the number of updated circuits
in the dialog box is correct.
Click the Circuits tab and verify that no incomplete circuits are displayed.
