10 Logical switch overview This chapter describes the logical switch and logical fabric features. For information about device sharing with Virtual Fabrics, see "FC-FC Routing and Virtual Fabrics" on page 496. The following platforms are Virtual Fabrics-capable: • Brocade DCX and DCX-4S • Brocade 5300 • Brocade 5100 For additional information about supported switches and port types, see "Supported platforms for Virtual Fabrics" on page 206. Virtual Fabrics and Admin Domains are mutually exclusive and are not supported at the same time on a switch. 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. Figure 14 on page 197 shows a switch before and after enabling Virtual Fabrics. The switch must be Virtual Fabrics-capable (Brocade DCX, DCX-4S, 5300, or 5100). 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. In this example, the switch has 10 ports, labeled P0 through P9. 196 Fabric OS Administrator's Guide 53-1001336-01
