Ethernet Circuit Configurations

9.4 Ethernet Circuit Configurations
Ethernet circuits can link ONS nodes through point-to-point, shared packet ring, or hub and spoke
configurations. Two nodes usually connect with a point-to-point configuration. More than two nodes
usually connect with a shared packet ring configuration or a hub and spoke configuration. This section
includes procedures for creating these configurations and also explains how to create Ethernet manual
cross-connects. Ethernet manual cross-connects allow you to cross connect individual Ethernet circuits
to an STS channel on the ONS 15327 optical interface and also to bridge non-ONS SONET network
segments.
Before making Ethernet connections, choose a STS-1, STS-3c, STS-6c, or STS-12c circuit size.
Note
Note When making an STS-6c or STS-12c Ethernet circuit, Ethernet cards must be configured as Single-card
EtherSwitch. Multicard mode does not support STS-6c or STS-12c Ethernet circuits.
9.4.1 Point-to-Point Ethernet Circuits
The ONS 15327 can set up a point-to-point (straight) Ethernet circuit as Single-card or Multicard.
Multicard EtherSwitch limits bandwidth to STS-3c of bandwidth between two Ethernet circuit points,
but allows you to add nodes and cards and make a shared packet ring. Single-card EtherSwitch allows a
full STS-12c of bandwidth between two Ethernet circuit points.
