    1: I HAPTER NTRODUCING THE Configuration Rules The topology rules for 100Mbps Fast Ethernet are slightly different to for Fast Ethernet those for 10Mbps Ethernet. Figure 6 illustrates the key topology rules and provides examples of how they allow for large-scale Fast Ethernet networks.

  • Page 21: Configuration Rules With Full Duplex

    The key topology rules are: Configuration Rules The Switch provides full duplex support for all its ports. Full duplex allows with Full Duplex packets to be transmitted and received simultaneously and, in effect, doubles the potential throughput of a link. With full duplex, the Ethernet topology rules are the same, but the Fast Ethernet rules are: Maximum UTP cable length is 100m (328ft) over Category 5 cable.
