Logging into the ONS 15454
2.5.1 Creating Login Node Groups
When you log into an ONS 15454 node, only ONS 15454s optically connected (i.e., with DCC
connections) to the node will display in network view. However, you can create a login node group to
view and manage ONS 15454s that only have an IP connection. For example, logging into Node 1 in
Figure 2-2 displays Node 2 and Node 3 because they are optically connected to Node 1. Nodes 4, 5, and
6 do not display because DCC connections do not exist. To view all six nodes at once, you create a login
node group with the IP addresses of Nodes 1, 4, and 5. Those nodes, and all nodes optically connected
to them, display when you log into any node in the group.
Caution ONS 15454s propogate VLANs whenever a node appears on the same network view of another node
regardless of whether the nodes connect through DCC or not. For example, if two ONS 15454s
without DCC connectivity belong to the same Login Node Group, then whenever CTC gets launched
from within this login node group, VLANs propogate from one to another. This happens even though
the ONS 15454s do not belong to the same SONET ring.
