Explanation

Login types in Switched Fabric Fabric services define three login types: - Fabric login (FLOGI): Performed between an N_Port and an F_Port. To log on to the fabric, a node sends a FLOGI frame with the WWNN and WWPN parameters to the login service at the predefined FC address FFFFFE (Fabric Login Server). In turn, the switch accepts the login and returns an Accept (ACC) frame with the assigned FC address for the node. Immediately after the FLOGI, the N_Port registers itself with the local Name Server on the switch, indicating its WWNN, WWPN, port type, class of service, assigned FC address and so on. After the N_Port has logged in, it can query the name server database for information about all other logged in ports. - Port login (PLOGI): Performed between two N_Ports to establish a session. The initiator N_Port sends a PLOGI request frame to the target N_Port, which accepts it. The target N_Port returns an ACC to the initiator N_Port. Next, the N_Ports exchange service parameters relevant to the session. - Process login (PRLI): Also performed between two N_Ports. This login relates to the FC-4 ULPs, such as SCSI. If the ULP is SCSI, N_Ports exchange SCSI-related service parameters.
