Cabletron Systems SmartSTACK 10 ELS10-26, User Manual

Page: 27 / 116

Introduction
1-17
Figure 1-9 shows two Ethernet segments that take advantage of the
virtual workgroup feature of the SmartSTACK 10 ELS10-26 and the
increased bandwidth applied to each A and B host.
Figure 1-9. Using the SmartSTACK 10 ELS10-26 to Create Virtual
Workgroups
to Help Optimize Bandwidth
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
10 Mbps bandwidth.
Ports that are not part of a workgroup will receive and transmit
packets from any ports. However, if you configure the
SmartSTACK 10 ELS10-26 with workgroup A and B, as shown in
Figure 1-9, broadcast traffic from workgroup A ports will not be
seen on workgroup B ports, and vice versa.
