Cisco ONS 15454 SDH Reference Manual, R5.0

Chapter 14 Ethernet Operation
14.5.2 E-Series Point-to-Point Ethernet Circuits
14.5.2 E-Series Point-to-Point Ethernet Circuits
The ONS 15454 SDH can set up a point-to-point (straight) Ethernet circuit as single-card, port-mapped
or multicard circuit. Multicard EtherSwitch limits bandwidth to VC4-3c between two Ethernet circuit
points, but allows adding nodes and cards and making a shared packet ring (Figure 14-18).
Figure 14-18 Multicard EtherSwitch Point-to-Point Circuit
Figure 14-19 shows a single-card EtherSwitch. Port-mapped mode allows a full VC4-4c of bandwidth
between two Ethernet circuit endpoints.

Note A Port-mapped point-to-point circuit does not contain a VLAN.
