Workgroups 1-11
There is extra security — Hub segments can be isolated from the
cascaded segments, so that only workstations on the same hub
segment can communicate with each other.
Port switching enables you to extend any existing workgroups you
may have, across the whole network infrastructure, including
shared Ethernet workgroups.
