April 2008
Chapter 14 Ethernet Operation
14.5 E-Series Circuit Configurations
Note In this chapter, “cross-connect” and “circuit” have the following meanings: Cross-connect refers to the
connections that occur within a single ONS 15454 SDH to allow a circuit to enter and exit an
ONS 15454 SDH. Circuit refers to the series of connections from a traffic source (where traffic enters
the ONS 15454 SDH network) to the drop or destination (where traffic exits an ONS 15454 SDH
network).
Figure 14-17 G-Series Manual Cross-Connects
14.5 E-Series Circuit Configurations
Ethernet circuits can link ONS nodes through point-to-point (straight), 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.
Ethernet manual cross-connects allow you to cross connect individual Ethernet circuits to an STM
channel on the ONS 15454 SDH optical interface and also to bridge non-ONS SDH network segments.
For circuit configuration procedures, refer to the “Create Circuits and Low-Order Tunnels” chapter of
the Cisco ONS 15454 SDH Procedure Guide.
Note Before making Ethernet connections, choose an VC4, VC4-2c, VC4-3c, or VC4-4c circuit size.
Note To make an VC4-4c Ethernet circuit, Ethernet cards must be configured in single-card EtherSwitch or
port-mapped mode. Multicard mode does not support VC4-4c Ethernet circuits.
14.5.1 Port-Mapped Mode and Single-card EtherSwitch Circuit Scenarios
Four scenarios exist for provisioning maximum single-card EtherSwitch bandwidth:
1. VC4-4c
2. VC4-2c + VC4-2c
3. VC4-2c + VC4 + VC4
4. VC4 + VC4 + VC4 + VC4
Note When configuring Scenario 3, the VC4-2c must be provisioned before either of the VC4 circuits.When
configuring Scenarios 3 and 4, the STM 6c must be provisioned before the smaller STM circuits.
