Internal Segments
Figure 1-8
You use management software to configure the segments. You can:
Connect and isolate the segments from their associated cascaded
segments.
Switch the ports between the segments (port switching).
The ability to configure the segments allows you to create flexible
workgroups, as shown in Figure 1-9, which can change and grow with
your needs.
