Cisco Systems 9124E Defined zone, Directory service, Domain ID, EPort, EECredit, EIA rack, Error

defined zone	The set of all zone objects defined in the fabric. May include multiple zone
configuration	configurations. See also zone, zone configuration.
directory service	See SNS.
DLS	Dynamic load sharing. Dynamic distribution of traffic over available paths. Allows for
	recomputing of routes when an Fx_Port or E_Port changes status.
domain ID	Unique identifier used in routing frames for all switches in a fabric. Usually assigned by
	the principal switch, but can be assigned manually. The domain ID for an HP switch
	can be any integer between 1 and 239. The default domain ID is usually 1.
E_D_TOV	Error-detect time-out value. The minimum time a target waits for a sequence to complete
	before initiating recovery. Can also be defined as the maximum time allowed for a
	round-trip transmission before an error condition is declared.
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 U_Port.
EE_Credit	End-to-end credit. The number of receive buffers allocated by a recipient port to an
	originating port. Used by Class 1 and Class 2 services to manage the exchange of
	frames across the fabric between source and destination.
EIA rack	A equipment storage rack that meets the standards set by the EIA (Electronics Industry
	Association ).
enabled zone	The currently enabled configuration of zones. Only one configuration can be enabled
configuration	at a time. See also zone,zone configuration.
end-to-end flow	A facility that governs flow of class 1 and class 2 frames
control	between N_Ports.
error	With respect to FC, a missing or corrupted frame, time-out, loss of synchronization, or
	loss of signal (link error).
exchange	The highest-level FC mechanism used for communication between N_Ports. Composed
	of one or more related sequences; can work in one or both directions.
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 U_Port.
fabric	An FC network containing two or more switches in addition to hosts and devices. May
	also be called a switched fabric.
fabric name	The unique identifier assigned to a fabric and communicated during login and port
	discovery.
FCIA	Fibre Channel Industry Association. An international organization of FC industry
	professionals. Among other things, provides oversight of ANSI and industry standards.
FCP	Fibre Channel Protocol. Mapping of protocols onto the FC standard protocols. For
	example, SCSI FCP maps SCSI-3 onto FC.
FCS switch	Fabric Configuration Server switch. One or more designated HP switches that store and
	manage the configuration and security parameters for all switches in the fabric.
