Glossary interoperability Ability to communicate, execute programs, or transfer data between various functional units over a network. interoperability mode (interop mode) - An operating mode, set through management software, that allows products to operate in homogeneous or heterogeneous fabrics. interswitch link (ISL) - Physical expansion port (E_Port) connection between two directors in a fabric. IOCDS A data set that contains an I/O configuration definition built by the IOCP. IOCP See input/output configuration program. IP address See internet protocol address. IPL See initial program load. ISL See interswitch link. jumper cable Optical cable that provides physical attachment between two devices or between a device and a distribution panel. See also trunk cable. latency The amount of time it takes for data transmission to pass through a switching device. When used in reference to a Fibre Channel switching device, latency refers to the amount of time elapsed between receipt of a data transmission at a switch's incoming F_Port (from the originating node port) to retransmission of that data at the switch's outgoing F_Port (to the destination N_Port). LIN See link incident. link Physical connection between two devices on a switched fabric. link incident (LIN) - Interruption to a Fibre Channel link due to loss of light or other causes. 16 Directors and Edge Switches Glossary
