5.3 Ring-to-Ring Interconnection
In the following examples, the form “5/1/1” represents “Slot 5, Port 1, STS 1.” For VTs add the normal
VT Group and VT ID extensions. These examples also assume that the slots/ports have been
auto-provisioned (via a plug-in event) and that the ports involved have been placed into the in service
state using a port configuration command, for example, ED-OCN.
For the examples in this section, both rings traverse the same node; therefore, only a single
cross-connection is required to create the ring-to-ring connection. Use the network map shown in
Figure 5-2 with the node named “Cisco” in the nexus.
