Configuration The way in which a system is set up. May refer to hardware or software.
Hardware: The number, type, and arrangement of components that make up a
system or network.
Software: The set of parameters that guide switch operation. May include general
system parameters, IP address information, Domain ID, and other information.
Modifiable by any login with administrative privileges.
May also refer to a set of zones.
CRC Cyclic redundancy check. A check for transmission errors that is included in every
data frame.
data word A type of transmission word that occurs within frames. The frame header, data field,
and CRC all consist of data words.
defined zone The set of all zone objects defined in the fabric. May include multiple zone
configuration configurations.
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 for all switches in a fabric, used in routing frames. Usually
automatically 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. Generally, the
default Domain ID is 1.
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.
E_Port Expansion port. A type of switch port that can be connected to an E_Port on
another switch to create an ISL.
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 2 services to manage the exchange of frames
across the fabric between source and destination.
enabled zone The currently enabled configuration of zones. Only one configuration can be
configuration enabled at a time.
end-to-end flow Governs flow of class 1 and 2 frames between N_Ports.
control
error As applies to Fibre Channel, a missing or corrupted frame, time-out, loss of
synchronization, or loss of signal (link errors).
