In a point-to-point connection, the port address is assigned by the port with the lowest WWN: • Only the Port segment is used. • One device takes the address 00000000 and the other device is assigned 00000001.
In a private loop (not connected to a switch) a public device will only use the 8- bit AL_PA: • A private loop is not connected to a switched fabric, so all NL_Ports can only communicate with each other based upon the ALPA which is assigned to each port during loop initialization. • The Domain and Area segments are not used.
