Connectivity Rules

When adding hubs (repeaters) to your network, please follow the
connectivity rules listed below for Ethernet or Fast Ethernet.
However, note that because switches break up the path for
connected devices into separate collision domains, you should not
include the switch or connected cabling in your calculations for
cascade length involving other devices.
