Connectivity Rules

When adding hubs (repeaters) to your network, please follow the standard
connectivity rules for Ethernet and 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.
