Connectivity Rules

When adding hubs (repeaters) to your network, please follow the standard

connectivity rules 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.
