XPath OS 7.4.x command reference guide 287
end-to-end flow
control
Governs flow of Class 1 and 2 frames between N_Ports. See also EE_Credit.
entry fabric The basic software license that allows one E_Port per switch.
EOF End of frame. A group of ordered sets used to mark the end of a frame.
error As it applies to the Fibre Channel industry, a missing or corrupted frame, timeout, loss of
synchronization, or loss of signal (link errors). See also loop failure.
Ethernet Popular protocol for LANs.
EVMd Event management database. Delivers FDMI-related events.
exchange The highest-level Fibre Channel mechanism used for communication between N_Ports.
Composed of one or more related sequences, it can work in either one or both directions.
F_BSY Fabric port busy frame. A frame issued by the fabric to indicate that a frame cannot be
delivered because the fabric or destination N_Port is busy.
F_Port Fabric port. A port that is able to transmit under fabric protocol and interface over links. Can
be used to connect an N_Port to a switch. See also FL_Port, Fx_Port.
F_RJT Fabric port reject frame. A frame issued by the fabric to indicate that delivery of a frame is
being denied, perhaps because a class is not supported, there is an invalid header, or no
N_Port is available.
fabric A Fibre Channel network containing two or more switches in addition to hosts and devices.
Also referred to as a switched fabric. See also cascade, SAN, topology.
Fabric Mode One of two possible modes for an L_Port, in which the L_Port is connected to another port that
is not loop capable, using fabric protocol.
fabric name The unique identifier assigned to a fabric and communicated during login and port discovery.
fabric port count The number of ports available for connection by nodes in a fabric.
fabric services Codes that describe the communication to and from any well-known address.
fabric topology The arrangement of switches that form a fabric.
failover Describes the process of one CP passing active status to another CP. A failover is
nondisruptive.
FAN Fabric address notification. Retains the AL_PA and fabric address when a loop reinitializes, if
the switch supports FAN.
fan-in The ratio of hosts to storage devices; the view of the SAN from the storage port’s perspective.
fan-out The ratio of storage devices to hosts; the view of the SAN from the host port’s perspective.
FC-0 Lowest layer of Fibre Channel transport. Represents physical media.
FC-1 Layer of Fibre Channel transport that contains the 8b/10b encoding scheme.
FC-2 Layer of Fibre Channel transport that handles framing and protocol, frame format,
sequence/exchange management, and ordered set usage.
FC-3 Layer of Fibre Channel transport that contains common services used by multiple N_Ports in a
node.
FC-4 Layer of Fibre Channel transport that handles standards and profiles for mapping upper-level
protocols, such as SCSI and IP, onto the Fibre Channel Protocol.
FC-AL-3 The Fibre Channel Arbitrated Loop standard defined by ANSI. Defined on top of the FC-PH
standards.
FC-AV Fibre Channel audio visual.
FCC Federal Communications Commission.
FC-CT Fibre Channel common transport.
FC-FG Fibre Channel generic requirements.
FC-FLA The Fibre Channel fabric loop-attach standard defined by ANSI.
FC-FS Fibre Channel framing and signaling.
FC-GS Fibre Channel generic services.
