E_Port
Expansion port. A type of switch port that can be connected to an E_Port on another switch to create an ISL. See
also ISL.
ELP
Exchange link parameters.
ELS
Extended link service. ELSs are sent to the destination N_Port to perform the requested function or service. ELS is a
Fibre Channel standard that is sometimes called a Fibre Channel Physical (FC_PH) ELS.
EM
Environmental monitor. Monitors FRUs and reports failures.
embedded port
An embedded port (or domain controller) communicates and gets updates from other switches' embedded ports.
The well-known address is fffcdd, where dd is the domain number.
entry fabric

EOF
End of frame. A group of ordered sets used to mark the end of a frame.
error
As applied to the Fibre Channel industry, a missing or corrupted frame, time-out, loss of synchronization, or loss of
signal (link errors).
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, either
because a class is not supported, the existence of an invalid header, or no N_Port available.
fabric
A Fibre Channel network containing two or more switches in addition to hosts and devices. Also called a switched
fabric. See also SAN, topology.
