Chapter 14 Add and Remove Nodes
NTP- D105 Add an SNCP Node
• CTC computers are directly connected to other nodes on the same subnet.
If the conditions are not present, continue with Step 10. If conditions are present, complete the
“DLP-D65 Create a Static Route” task on page 17-56 on the node that will be added to the SNCP. Use
the following settings:
• Destination IP address: IP-address-of-the-CTC-computer-connected-to-the-new-node
• Net Mask: 255.255.255.255
• Next Hop: IP-address-of-the-Cisco-ONS-15454-SDH
• Cost: 1
To view gateway settings, see the “DLP-D249 Provision IP Settings” task on page 19-52.
Step 10 Log into the new node:
• If the node has a LAN connection and it appears on the network map, from the View menu, choose
Go to Other Node, then enter the new node.
• If the new node is not connected to the network, complete the “DLP-D60 Log into CTC” task on
page 17-49.
Step 11 Click the Alarms tab. Verify that no critical or major alarms are present, nor any facility alarms, such as
LOS, LOF, AIS-L, SF, and SD. If trouble is indicated (for example, a major alarm exists), resolve the
problem before proceeding. See Chapter 9, “Manage Alarms” or, if necessary, refer to the
Cisco ONS 15454 SDH Troubleshooting Guide.
Step 12 In network view, click the Circuits tab.
To view Partial circuits, click the Filter button and select PARTIAL from the Status drop-down list.
The Partial circuits, if any, are displayed.
To view Partial_TL1 circuits, click the Filter button and select PARTIAL_TL1 from the Status
drop-down list. The Partial_TL1 circuits, if any, are displayed.
Resolve any partial circuits (both Partial and Partial_TL1) in the network before proceeding. However,
if you want to continue with Step 13, match the number of partial circuits and circuit names that existed
before and after adding a path protection node. This ensures that no additional partial circuits are created
after this procedure is completed.
Step 13 (Optional) Create test circuits, making sure that they pass through the SNCP trunk (span) cards, and run
test traffic through the node to ensure that the cards are functioning properly. See the “NTP-D324 Create
a Manually Routed High-Order Circuit” procedure on page 6-60 and the “NTP-D62 Test High-Order
Circuits” procedure on page 6-66 for information.
Step 14 Create the DCC terminations on the new node. See the “DLP-D363 Provision Regenerator-Section DCC
Terminations” task on page 20-68.
Step 15 From the View menu, choose Go to Network View.
Step 16 Complete the “DLP-D197 Initiate an SNCP Force Switch” task on page 18-84 to switch traffic away
from the span that will be broken to connect to the new node.
Step 17 Two nodes will connect directly to the new node; remove their fiber connections:
a. Remove the east fiber connection from the node that will connect to the west port of the new node.
b. Remove the west fiber connection from the node that will connect to the east port of the new node.
Step 18 Replace the removed fibers with the fibers that are connected to the new node.
Step 19 Log out of CTC and log back into a node in the network.
Step 20 From the View menu, choose Go to Network View to display the SNCP nodes. The new node should
appear in the network map. Wait for a few minutes to allow all the nodes to appear.
