Configuring Your ELS10-26
3.11 DEFINING AND DELETING WORKGROUPS
The ELS10-26 allows you to define logical groups of associated
ports (virtual workgroups) to provide a more efficient flow of
traffic across your Ethernet network.
Virtual workgroups offer you the ability to limit broadcasts to
logical domains within the network. Workgroup destinations are
recognized by the ELS10-26 and packets are routed directly to
ports within the workgroup, eliminating the need to perform a
general broadcast across each segment of the network to find
specific host addresses.
Figure 3-3 shows an ELS10-26 that has been programmed to
identify workgroups A and B. Workgroup A uses ports 3 through
5,13 and 16 and workgroup B uses ports 7, 11, 16 and 24. Port 16
connects a segment that contains both workgroup A and
workgroup B hosts.
