Planning a Network with EtherSpeedII Switch Modules

Segment Switch in an Enterprise Network

To achieve a gradual transition from shared media to switched networks, you can use the EtherSpeedII 10/100BASE-T switch module or the EtherSpeedII 100BASE-FX switch module to aggregate traffic from stations connected to one or more hubs. Figure 2-5 shows such a network with switches used to connect shared-media hubs to a backbone switch. Stations connected to the EtherSpeedII switch module are associated with different segments through the configuration switching feature.
