When you set up a 12-Port 100BASE-TX FastModule as a
fully-configured workgroup module, the resultant logical network
configuration supports one workgroup per module. Because a
managed CoreBuilder 5000 hub may contain as many as seventeen
12-Port 100BASE-TX FastModules, it is possible to configure your hub
with a maximum of 17 workgroups or a maximum of 204 ports in a
single workgroup.
Workgroups are individual groups on modules set up to divide your
network layout into smaller isolated networks. The CoreBuilder 5000
100BASE-TX Workgroup FastModule is a Fast Ethernet module that
enables administrators to connect up to 12 network devices. You can
attach workstations to the 12-Port 100BASE-TX Workgroup FastModule
using RJ-45 connectors directly to the front of the module.
Workgroups:
Provide network administrators with high flexibility in organizing
their network.
Decrease the amount of traffic on the backplane segments of the
hubs in which the workgroups reside.
By creating module workgroup networks instead of separate
backplane segment networks, you can configure a maximum of
17 workgroups per hub using no backplane bandwidth.
