Introduction to FIP Snooping

Many data centers use Ethernet for TCP/IP networks and Fibre Channel for storage area networks (SANs).

Implementing Fibre Channel over Ethernet (FCoE) allows transmission over Ethernet networks, while preserving Fibre Channel‘s lossless, point-to-point transmission ability for reliable and efficient access of disk servers. FCoE is part of the International Committee for Information Technology Standards T11 FC-BB-5 standard.

FCoE Initialization Protocol (FIP) allows Ethernet nodes (Enode) to find, and set up virtual links with, FCoE forwarders (FCFs) that then connect to the fibre channel fabric.

FIP snooping monitors FCoE‘s virtual links and suppresses traffic not related to maintaining or establishing these virtual links to achieve a level of security comparable to native Fibre Channel.
