Logical switch overview

This chapter describes the logical switch and logical fabric features. For information about device
sharing with Virtual Fabrics, refer to
For information about supported switches and port types, refer to
Fabrics"
Virtual Fabrics and Admin Domains are mutually exclusive and are not supported at the same time
on a switch.
NOTE
A note on terminology: Virtual Fabrics is the name of the suite of features. A logical fabric is a type
of fabric that you can create using the Virtual Fabrics suite of features.

Logical switch overview

Traditionally, each switch and all the ports in the switch act as a single Fibre Channel switch (FC
switch) that participates in a single fabric. The logical switch feature allows you to divide a physical
chassis into multiple fabric elements. Each of these fabric elements is referred to as a logical
switch. Each logical switch functions as an independent self-contained FC switch.
NOTE
Each chassis can have multiple logical switches.

Default logical switch

To use the Virtual Fabrics features, you must first enable Virtual Fabrics on the switch. Enabling
Virtual Fabrics creates a single logical switch in the physical chassis. This logical switch is called
the default logical switch, and it initially contains all of the ports in the physical chassis.
