Cisco ONS 15454 Product Overview
Ethernet
Single-Card and Multicard EtherSwitch
The ONS 15454 supports single-card and multicard EtherSwitch.
When you provision single-card EtherSwitch, each Ethernet card is a single switching
entity within the ONS 15454. This option allows STS-12c of bandwidth between two
Ethernet circuit points. Single-card EtherSwitch supports one STS-12c, two STS-6c,
four STS-3c, or twelve STS-1 circuits.
Figure 19 Single-card EtherSwitch
When you provision multicard EtherSwitch, two or more Ethernet cards act as a single
layer 2 switch. Multicard EtherSwitch supports one STS-6c shared packet ring, two
STS-3c shared packet rings, or six STS-1 shared packet rings. The bandwidth of the
single switch formed by the Ethernet cards matches the bandwidth of the provisioned
Ethernet circuit up to STS-6c worth of bandwidth.
