G-port, L-port, and F-port of the port status of the fibre switch

N Ports: Node port node ports; nodes connection points; terminal of Fibre Channel communication

F Port: Fabric port Fibre Port; A switched connection port, the "intermediate port" of two n-Port connections

NL Ports: node loop port loop ports, connecting to other ports via their NL port, or connecting to a switched optical network via a separate FL port, or the NL port connecting to F port to F port to n Port (via switch)

FL Port: Fabric Loop port fibre loop ports; a shared bit Al device provides access to the fibre network service port; example, NL Port to FL port to f port to n Port

E Port: Expansion port Extension ports for connecting multiple switches via ISL (internal exchange link)

G Port: Generic Port Universal ports, can switch between f port and E port according to connection mode

Te Port: trunked expansion Port converged expansion ports, connecting multiple e ports for high traffic

Fibre Channel also defines a range of other ports that can be used to receive and transmit Fibre channel data, including "Nl_ports," "F_ports," "E_ports," and so on.

Device (node) port

N_port = "Fabric Direct connection Device"

Nl_port = "Loop connection device"

Switch port

E_port = "Extended port" (Switch to switch)

F_port = "Fabric Port"

Fl_port = "Fabric Loop port"

G_port = "Universal (Generic) port-can be converted to E or F"

Mixing fabric with arbitrated loop technology is feasible, and a fabric port of the switch can be used as part of the loop, and data can be transferred from the switch to the loop loop. A fabric port that works properly in the loop environment is called the "Fl_port." Although the routing of data and control information needs to be accessed through other ports for links, most fibre Channel functionality is not related to the topology
