FCoE: FIP snooping

Fibre Channel over Ethernet (FCoE) Initialization Protocol (FIP) snooping is a security mechanism that is designed to prevent unauthorized access and data transmission to a Fibre Channel (FC) network. It works by filtering traffic to permit only servers that have logged in to the FC network to access the network. You enable FIP snooping on FCoE VLANs when the switch is being used as an FCoE transit switch connecting FC initiators (servers) on the Ethernet network to FCoE forwarders (FCFs) at the FC storage area network (SAN) edge.
