Glossary
implicit list In administrative domains, a list of all switches, ports, and devices that have not been explicitly declared
in any AD (including AD0). The implicit list changes as other ADs are created and resources consumed
by them. See also AD0, automatic member, and explicit list.
in-band Transmission of management protocol over the Fibre Channel.
initiator A server or workstation on a Fibre Channel network that initiates communications with storage devices.
See also target.
Insistent
Domain ID
mode
Sets the domain ID of a switch as insistent, so that it remains the same over reboots, power cycles,
failovers, and fabric reconfigurations.
intercabinet A specification for copper cabling that allows up to 33-m distances between cabinets.
intermix Allows any unused bandwidth in a Class 1 connection.
interop mode The interoperability mode that enables Brocade switches and other vendor switches to exchange
interoperability parameters, allowing their fabrics to merge into one fabric with one principal switch
and unique domain IDs. This mode is enabled using the interopMode command. Using interop mode
significantly reduces the advanced functionality of Brocade switches.
interswitch
link
See ISL.
intracabinet A specification for copper cabling that allows up to a 13-m (42-ft) distance within a single cabinet.
IOCDS I/O Configuration Data Set.
IOCTL I/O control.
IOD In-order delivery. A parameter that, when set, guarantees that frames are either delivered in order or
dropped.
IPSec A framework of open standards to ensure private, secure communications over Internet Protocol (IP)
networks through the use of cryptographic security services. See also IKE and SA.
IQN iSCSI Qualified Name. An iSCSI address that uniquely identifies an iSCSI devi
ce on the network. It is
the equivalent of a Fibre Channel WWN and is in human readable format.
ISL Interswitch link. A Fibre Channel link from an E_Port of one switch to an E_Port of another. See also
cascade and E_Port.
ISL oversub-
scription ratio
The ratio of the number of free ports (non-ISL) to the number of ISLs on a switch.
isolated
E_Port
An E_Port that is online but not operational due to overlapping domain IDs or nonidentical parameters
(such as E_D_TOVs). Frequently appears in the command line or logs as segmented. See also E_Port.
ISP Internet service provider.
