Introduction
Figure 1-6 shows two Ethernet segments that take advantage of the
virtual workgroup feature of the SmartSTACK 100 ELS100-16TX
and the increased bandwidth applied to each A and B host.

A host from workgroup A can limit a broadcast to all hosts within
workgroup A and prevent the broadcast from going across the
network and adding to the amount of contention for the limited
100 Mbps bandwidth.
Ports that are not part of a workgroup will receive and transmit
packets from any ports. However, if you configure the
SmartSTACK 100 ELS100-16TX with workgroup A and B, as
shown in Figure 1-6, broadcast traffic from workgroup A ports will
not be seen on workgroup B ports, and vice versa.
