Fabric Log A log recorded at the EFC Manager application that displays the time
and nature of changes made to a managed fabric, such as a switch
added or removed, ISL added or removed, fabric renamed or
persisted, or zone set activated.
fabric login The fabric login (FLOGI) command is initiated by a fabric-attached
node port (N_Port) and establishes the operating parameters and
topology required for fabric login. The command is accepted by a
fabric port (F_Port).
fabric loop port In Fibre Channel protocol, a switch port with arbitrated loop
capability that communicates with a node loop port (NL_Port) of an
attached FC-AL device. See also node loop port, contrast with hub port.
fabric port In Fibre Channel protocol, a switch port that communicates with a
node port (N_Port) of an attached Fibre Channel device. See also node
port.
fabric switch A highly-available Fibre Channel switch with a low port count that
provides any-to-any port connectivity between devices (nodes)
connected to a switched fabric. A fabric switch transmits data frames
between nodes in accordance with the address information provided
in the associated frame headers. Fabric switches are well suited for
usein workgroupor departmentalcomputing environments.Contrast
with director.
failover Automatic and nondisruptive transition of operation from an active
FRU that failed to a functional backup FRU.
FC-0 The Fibre Channel layer that describes the physical link between two
ports, including the transmission medium, transmitter and receiver
circuitry, and interfaces.
FC-1 The Fibre Channel layer that definesthe 8B/10B encoding, decoding,
and transmission protocol.
FC-2 The Fibre Channel layer that specifies the signaling protocol, rules,
and mechanisms required to transfer data blocks. This layer is
complex and provides different classes of service, packetization,
sequencing, error detection, segmentation, and reassembly of
transmitted data.
