Fibre Channel Over Ethernet (FCoE)

Fibre Channel over Ethernet (FCoE) is a proposed mapping of Fibre Channel over selected full duplex IEEE 802.3 networks.


This protocol proposal is led by Cisco and is under discussion in the T11 FC-BB Working group.

Protocol dependencies

  • Ethernet: FCoE uses Ethernet as its transport protocol. The IEEE-assigned Ethertype for FCoE traffic is 0x8906.

Example traffic



The FCoE dissector is fully functional.

Preference Settings


Example capture files

Display Filter

Show only the FCoE based traffic:


Show only FCoE traffic with start-of-frame value SOFn3:

 fcoe.sof == SOFn3 

Show only FCoE traffic with bad CRCs:

 fcoe.crc_bad == True 

Capture Filter

Capture only the FCoE traffic over the standard Ethertype (0x8906):

 eth.type == 0x8906
