> # Information 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). The switch can connect separated SAN islands using Fibre Channel over IP (FCIP) .

> FCIP uses TCP as a network layer transport. The DF bit is set in the TCP header.

> Note For more information about FCIP protocols, refer to the IETF standards for IP storage at http://www.ietf.org. Also refer to Fibre Channel standards for switch backbone connection at http://www.t11.org (see FC-BB-2).
