Port Types

The switch supports generic ports (G_Port, GL_Port), fabric ports (F_Port,

FL_Port), and expansion ports (E_Port). Switches come from the factory with all ports configured as GL_Ports. Generic, fabric, and expansion ports function as follows:

A GL_Port self-configures as an FL_Port when connected to a public loop device, as an F_Port when connected to a single public device, or as an E_Port when connected to another switch. If the device is a single device on a loop, the GL_Port will attempt to configure first as an F_Port, then if that fails, as an FL_Port.

A G_Port self-configures as an F_Port when connected to a single public device, or as an E_Port when connected to another switch.

An FL_Port supports a loop of up to 126 public devices. An FL_Port can also configure itself during the fabric login process as an F_Port when connected to a single public device (N_Port).

An F_Port supports a single public device. F_Ports also support N_Port ID Virtualization (NPIV).

E_Ports enable you to expand the fabric by connecting QLogic 9000 Series switches with other switches. QLogic 9000 Series switches self-discover all inter-switch connections. Refer to “Multiple Chassis Fabrics” on page 2-6for more information about multiple chassis fabrics.
