Port Modes
SANbox2-8c switches support the following port modes:
■ Generic ports (GL_Port and G_Port)
■ Fabric ports (FL_Port and F_Port)
■ Translated loop ports (TL_Port)
■ Expansion ports (E_Port)
Switches come from the factory with all ports configured as GL_Ports. GL_Ports
self-configure in the following ways:
■ FL_Port when connected to a loop of public devices
■ F_Port when connected to a single public device. 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.
■ E_Port when connected to another FC-SW-2 compliant switch
G_Ports self-configure in the following ways:
■ F_Port when connected to a public device
■ E_Port when connected to another FC-SW-2 compliant switch
A TL_Port supports private loop devices and must be configured explicitly. Refer
to the SANbox2-8c/16 Switch Management User’s Guide for more information
about defining port modes.
2.2.4.1
Fabric Ports
An FL_Port can support 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).
