Chapter 13 Add and Remove Nodes
Before You Begin
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
, 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
Complete the following steps if the node is on the same subnet as other path protection nodes, it is not
provisioned as an ENE (see the
“NTP-H21 Set Up CTC Network Access” procedure on page 3-6
), and
a CTC computer will directly connect to the node while other CTC computers are directly connected to
other path protection nodes. If not, continue with
.
a.
Click the
Provisioning > Network > General
tabs. View the IP Address and Net/Subnet Mask
Length fields to verify the node is on the same subnet as other path protection nodes.
b.
Click the
Static Routing
tab and click
Create
.
c.
In the Create Static Route dialog box, enter the following settings:
•
Destination IP address:
Local-PC-IP-address
•
Net Mask:
255.255.255.255
•
Next Hop:
IP-address-of-the-Cisco-ONS-15310- MA
•
Cost:
1
d.
Click
OK
.
Step 14
(Optional) Create test circuits, making sure they pass through the path protection line ports, and run test
traffic through the node to ensure the ports are functioning properly. See the
Manually Routed Optical Circuit” procedure on page 5-35
“NTP-H50 Test Optical Circuits”
for information.
Step 15
Create the DCC terminations on the new node. See the
“DLP-H52 Provision Section DCC Terminations”
.
Step 16
From the View menu, choose
Go to Network View
.
Step 17
Complete the
“DLP-H166 Initiate a Path Protection Force Switch on a Span” task on page 17-58
to
switch traffic away from the span that will be broken to connect to the new node.
Step 18
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 19
Replace the removed fibers with the fibers that are connected to the new node.
Step 20
Log out of CTC and log back into a node in the network.
Step 21
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 22
Click the
Circuits
tab and wait for all the circuits to appear, including spans. Count the number of partial
circuits.
Step 23
Ensure that nodes involved in the node addition operation are in the initialized state. This is because,
CTC does not consider nodes that are not initialized (they appear as gray icons in the CTC network map)
when evaluating the circuits.
