Overview Depending on device connections, G_Ports work as follows: ■ If the G_Port is attached to a Fibre Channel device, the port functions as a fabric port (F_Port). An F_Port is the interface on a director that connects to a device N_Port. ■ If the G_Port is attached to another director to form an Interswitch Link (ISL), the port functions as an expansion port (E_Port). A multi-switch fabric is formed through multiple directors and ISLs.
