Finisar Brocade Fabric Watch manual FC-AL-3 FC-FLA FCP FC-PH-1, 2, 3 FC-PI FC-PLDA

Domain ID As applies to SilkWorm switches, a unique number between 1 and 239 that identifies the switch to the fabric and is used in routing frames. Usually automatically assigned by the switch, but can be manually assigned.

E_D_TOV Error Detect Time-out Value; the minimum amount of 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. See also R_A_TOV, RR_TOV.

E_Port

EE_Credit

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.

End-to-end Credit; the number of receive buffers allocated by a recipient port to an originating port. Used by Class 1 and 2 services to manage the exchange of frames across the fabric between source and destination. See also End-to-end Flow Control, BB_Credit.

EIA Rack A storage rack that meets the standards set by the Electronics Industry Association.

Enabled Zone Configuration

End-to-end Flow Control

Error

The currently enabled configuration of zones. Only one configuration can be enabled at a time. See also Defined Configuration, Zone Configuration.

Governs flow of class 1 and 2 frames between N_Ports. See also EE_Credit.

As applies to fibre channel, a missing or corrupted frame, time-out, loss of synchronization, or loss of signal (link errors). See also Loop Failure.

Exchange	The highest level fibre channel mechanism used for communication between
	N_Ports. Composed of one or more related sequences, and can work in either 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 FL_Port, Fx_Port.
Fabric	A fibre channel network containing two or more switches in addition to hosts and
	devices. May also be referred to as a switched fabric. See also Topology, SAN,
	Cascade.
Fabric Name	The unique identifier assigned to a fabric and communicated during login and
	port discovery.
