A Fibre Channel over Ethernet (FCoE) transit switch is a Layer 2 data center bridging (DCB) switch that can transport FCoE frames. When used as an access switch for FCoE devices, the FCoE transit switch implements FCoE Initialization Protocol (FIP) snooping. A DCB switch transports both FCoE and Ethernet LAN traffic over the same network infrastructure while preserving the class of service (CoS) treatment that Fibre Channel (FC) traffic requires.
