Figure 22
shows a logical representation of the physical chassis and devices in
Figure 21
. As
shown in
Figure 22
, the devices are isolated into separate fabrics.

Logical fabric overview
A
logical fabric
is a fabric that contains at least one logical switch. The four fabrics shown in
Figure 21
and
Figure 22
are logical fabrics because they each have at least one logical switch.
You can connect logical switches to non-Virtual Fabrics switches and to other logical switches.
You connect logical switches to non-Virtual Fabrics switches using an ISL, as shown in
Figure 21
.
You connect logical switches to other logical switches in two ways:
•
Using ISLs
•
Using base switches and extended ISLs (XISLs)
