Description
Fabric port—supports a single public device (N_Port).
Fabric loop port —self discovers a single device (N_Port) or a loop of up to
126 public devices (NL_Port).
Generic port—self discovers as an F_Port or an E_Port.
Generic loop port—self discovers as an F_Port, FL_Port, or an E_Port.
GL_Port is the default port type. A single device on a public loop will
attempt to configure as an F_Port first, then if that fails, as an FL_Port.
Expansion port—the mode that a G_Port or GL_Port is in when attached by
an ISL (inter-switch link) to another fibre channel switch.
Donor port—allows buffer credits to be used by another port.
