connected to the same physical chassis.
You can also connect other switches to logical switches. In Figure 22 , P6 is an E_Port that forms an
inter-switch link (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.
