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
A G_Port
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
