(ISLs) and Cisco's extended ISLs (EISLs).
FCIP virtual E (VE) ports behave exactly like standard Fibre Channel E ports, except that the transport
in this case is FCIP instead of Fibre Channel. The only requirement is for the other end of the VE port
to be another VE port.
A virtual ISL is established over an FCIP link and transports Fibre Channel traffic. Each associated
virtual ISL looks like a Fibre Channel ISL with either an E port or a TE port at each end (see
