interop mode See interoperability mode.
inter-router ISL Two or more SAN routers can be interconnected using inter-router
interswitch links (ISLS) for box-level redundancy and/or to provide

are GE connections. The protocol used to communicate between the
routers over the GE connections could be Internet Fibre Channel
Protocol (iFCP).
interrupt A signal sent by a subsystem to the central processing unit (CPU) that
