Connectivity Guidelines
When adding hubs (repeaters) to your network, please follow the con-
nectivity rules listed below for Fast Ethernet. However, note that
because switches break up the path for connected devices into sepa-
rate collision domains, you should not include the switch or connected
cabling in your calculations for cascade length involving other devices.
Note: Network diameter is defined as the wire distance between the
two end stations in the same collision domain.
