Connectivity Rules; 1000 Mbps Gigabit Ethernet Collision Domain - SMC Networks SMC6824M Installation Manual

Connectivity Rules

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