Switch Ports
N_port—(Node port) An equipment port that is not loop capable. Used to
connect the equipment to the fabric.
NL_port—An equipment port that is loop capable. Used to connect an
equipment port to the fabric in a loop configuration through the FL_Port on a
switch.
F_port—A fabric port that is not in loop mode. Able to transmit under fabric
protocol, and interface over links. N_Ports on equipment connect to F_Ports
on switches.
FL_port—A fabric port on a switch that is in loop mode. Used to connect loop
capable NL_Ports to the switch in a loop configuration.
L_port—A node port (NL_port) or fabric port (FL_port) that has arbitrated
loop capabilities.
