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.
- ["Ethernet"]: FCoE uses ["Ethernet"] as its transport protocol. The IEEE-assigned Ethertype for FCoE traffic is 0x8906.
XXX - Add example decoded traffic for this protocol here (as plain text or Wireshark screenshot).
The FCoE dissector is fully functional.
Example capture file
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
You cannot directly filter PROTO protocols while capturing. However, if you know the ["TCP"] port used (see above), you can filter on that one.
Capture only the FCoE traffic over the standard Ethertype (0x8906):
eth.type == 0x8906
