Which Fibre Channel port type is a fabric port with arbitrated loop capabilities that connects to another node or switch port?

An N_Port is a standard node port for point-to-point or switched fabric connections only and does not support arbitrated loop (FC-AL) protocols.

An FL_Port is the switch-side fabric loop port that terminates connections from NL_Ports; it resides on the switch fabric rather than on the end node.

An E_Port is an expansion port used exclusively for inter-switch links (ISLs) between Fibre Channel switches and has no role in node connectivity or arbitrated loop topologies.

An NL_Port (Node Loop port) is a host or storage device port that implements Fibre Channel Arbitrated Loop (FC-AL) capabilities, allowing it to connect to other NL_Ports in a shared loop or to an FL_Port on a switch. It is the node-side port used in loop topologies, enabling arbitrated loop-based fabric participation from end devices.
