Connectivity Rules

When adding hubs (repeaters) to your network, please follow the connectivity rules listed below for Ethernet, Fast Ethernet, and Gigabit 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.
