You can also connect other switches to logical switches. In Figure 24 , 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
Figure 25 shows a logical representation of the physical chassis and devices in Figure 24 . As
shown in Figure 25 , the devices are isolated into separate fabrics.
FIGURE 25 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 “FC-FC
Routing and Virtual Fabrics” on page 492.
Logical fabric overview
A logical fabric is a fabric that contains at least one logical switch. The four fabrics shown in
Figure 24 and Figure 25 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 Figure 24 .
