Logical fabric overview

You can also connect other switches to logical switches. In 

, P6 is an E_Port that forms an 

ISL between Logical switch 4 and the non-Virtual Fabrics switch. Logical switch 4 is the only logical 
switch that can communicate with the non-Virtual Fabrics switch and D2, because the other logical 
switches are in different fabrics.

FIGURE 24

Logical switches connected to devices and non-Virtual Fabric switch

 shows a logical representation of the physical chassis and devices in 

. As 

shown in 

, the devices are isolated into separate fabrics.

Logical switches in a single chassis belong to separate fabrics

If you want to allow device sharing across fabrics in a Virtual Fabrics environment, see 

Logical fabric overview

A logical fabric is a fabric that contains at least one logical switch. The four fabrics shown in 

 are logical fabrics because they each have at least one logical switch.

You can connect logical switches to non-Virtual Fabric switches and to other logical switches.

You connect logical switches to non-Virtual Fabric switches using an ISL, as shown in 

.
