Planning a Network with EtherSpeedII Switch Modules

Replacing a Bridge

Using a switch instead of a bridge in the network can increase the aggregate network bandwidth. The “After” example in Figure 2-3 shows one server connected to a dedicated 10BASE-T port. It also shows the other server and additional clients attached using dedicated 100BASE-TX connections. This network configuration allows you to have switched 10 Mb/s Ethernet along with segmented 10 Mb/s Ethernet to conserve ports.
