Glossary
Cyclic redundancy check. A check for transmission errors that
is included in every data frame.
The set of all zone objects defined in the fabric. May
include multiple zone configurations. See also zone,
configuration.
See SNS.
Dynamic load sharing. Dynamic distribution of traffic over
available paths. Allows for recomputing of routes when an
Fx_Port or E_Port changes status.
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.
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.
Expansion port. A type of switch port that can be connected
to an E_Port on another switch to create an ISL. See also
trunking, U_Port.
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.
The currently enabled configuration of zones. Only one
configuration can be enabled at a time. See also zone,
configuration.
A facility that governs flow of class 1 and class 2 frames
between N_Ports.
With respect to FC, a missing or corrupted frame, time-out, loss
of synchronization, or loss of signal (link error).
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.
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.
