Logical fabric overview

A logical fabric is a fabric that contains at least one logical switch. The four fabrics shown in
Figure 21
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
You connect logical switches to other logical switches in two ways:

Logical switches connected to devices and non-Virtual Fabrics switch
shows a logical representation of the physical chassis and devices in
Figure 22, the devices are isolated into separate fabrics.

Logical switches in a single chassis belong to separate fabrics
and Figure 22 are logical fabrics because they each have at least one logical switch.
