Port Types
SANbox2-64 switches support 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.
E_Ports enable you to expand the fabric by connecting SANbox2-64 switches with
other switches. SANbox2-64 switches self-discover all inter-switch connections.

multiple chassis fabrics. Refer to the SANbox2-64 Switch Management User’s
Guide for more information about defining port types.
