About FCIP
The Fibre Channel over IP Protocol (FCIP) is a tunneling protocol that connects geographically
distributed Fibre Channel storage area networks (SAN islands) transparently over IP local area networks
(LANs), metropolitan area networks (MANs), and wide area networks (WANs).
FCIP uses TCP as a network layer transport.
To configure the IPS module for FCIP, you should have a basic understanding of the following concepts:
• FCIP and VE Ports
•
FCIP Links
• FCIP Profiles
•
FCIP Interfaces
FCIP and VE Ports
Figure 24-6 describes the internal model of FCIP with respect to Fibre Channel inter switch links (ISLs)
and Cisco’s enhanced ISLs (EISLs).
FCIP defines virtual E (VE) ports, which 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 a 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.
