configuration
1. A set of parameters that can be modified to fine-tune the operation of a switch. Use the configshow
command to view the current configuration of the switch.
2. In HP StorageWorks Zoning, a zoning element that contains a set of zones. The configuration is the
highest-level zoning element and is used to enable or disable a set of zones on the fabric. See also zone
configuration.
core PID
Core switch port identifier. The core PID must be set for Fabric OS 3.1 and earlier switches included in a
fabric of Fabric OS 4.1 switches. This parameter is located in the configure command of firmware
versions 3.1 and earlier. All version 4.1 switches and later use the core PID format by default; this
parameter is not present in the configure command for these switches.
credit
In Fibre Channel technology, the number of receive buffers available to transmit frames between ports. See
also BB_Credit.
defined zone configuration
The set of all zone objects defined in the fabric. Can include multiple zone configurations. See also error,
zone configuration.
D_ID
Destination identifier. A three-byte field in the frame header that indicates the address identifier of the
N_Port to which the frame is headed.
director
An HP StorageWorks Core Switch 2/64, SAN Director 2/128, or 4/256 SAN Director.
DLS
Dynamic load-sharing. Dynamic distribution of traffic over available paths. Allows for the recomputing of
routes when an Fx_Port or an E_Port changes status.
domain ID
A unique identifier for all switches in a fabric, used in routing frames. Usually assigned by the principal
switch, but can be assigned manually. The domain ID for an HP StorageWorks switch can be any integer
from 1 through 239.
edge fabric
A Fibre Channel fabric connected to an FC router through an EX_Port (where hosts and storage are
attached in a meta-SAN).
E_D_TOV
Error-detect timeout 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
is declared. See also R_A_TOV.
enabled zone configuration
The currently enabled configuration of zones. Only one configuration can be enabled at a time. See also
defined zone configuration, zone configuration.
E_Port
Expansion port. A standard Fibre Channel mechanism that enables switches to network with each other,
creating an ISL. See also ISL.
