Chapter 14 Add and Remove Nodes
NTP-A105 Add a Path Protection Node
•
CTC computers are directly connected to other nodes on the same subnet.
If the conditions are not present, continue with
. If conditions are present, complete the
Create a Static Route” task on page 17-73
on the node that will be added to the path protection. 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
•
Cost:
1
To view Gateway Settings, see the
“DLP-A249 Provision IP Settings” task on page 19-30
.
Step 8
Log into the new node:
•
If the node has a LAN connection and 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, log into it using the
.
Step 9
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 the
Cisco ONS 15454 Troubleshooting Guide
, as necessary.
Step 10
(Optional.) Create test circuits, making sure they pass through the path protection trunk cards, and run
test traffic through the node to ensure that the cards are functioning properly. See the
a Manually Routed OC-N Circuit” procedure on page 6-43
for information.
Step 11
Create the DCC terminations on the new node. See the
“DLP-A377 Provision Section DCC
Terminations” task on page 20-61
Step 12
From the View menu, choose
Go to Network View
.
Step 13
Complete the
“DLP-A197 Initiate a Path Protection Force Switch” task on page 18-68
to switch traffic
away from the span that will be broken to connect to the new node.
Step 14
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 15
Replace the removed fibers with the fibers that are connected to the new node.
Step 16
Log out of CTC and log back into a node in the network.
Step 17
From the View menu, choose
Go to Network View
to display the path protection nodes. The new node
should appear in the network map. Wait for a few minutes to allow all the nodes to appear.
Step 18
Click the
Circuits
tab and wait for all the circuits to appear, including spans. Count the number of
incomplete circuits.
Note
UNEQ-P alarms might appear on the nodes in your network; this is normal, and the alarms will
clear after the circuits are updated.
Step 19
In the network view, right-click the new node and choose
Update Circuits With New Node
from the
shortcut menu. Wait for the confirmation dialog box to appear. Verify that the number of updated circuits
in the dialog box is correct.
