Enterasys fn100 Betriebsanweisung

The FN100 allows you to define ports for logical groups of associated 
hosts to create workgroups. Workgroups provide an efficient flow of 
traffic across an Ethernet network by enabling you to limit broadcasts to 
logical domains within the network. The FN100 recognizes Workgroup 
destinations and routes broadcast packets directly to hosts within the 
workgroup, eliminating the need to perform a general broadcast across 
each segment of the network to find host addresses.

Workgroups are created by assigning workgroup IDs to specific FN100 
ports. A port is assigned to one workgroup at a time. Figure 1-14 shows 
two Ethernet segments using the workgroup feature of the FN100 to 
increase the bandwidth dedicated to each A and B host.

A host from workgroup A can limit a broadcast to all hosts within 
workgroup A or B and prevent the broadcast from going across the 
network and adding to the amount of contention for the limited 100 Mbps 
bandwidth.
