No FCOE is not supported on the 8100 series switch as it doesn’t support FIPS snooping.  FIPS snooping is required for FCoE.  The confusion will come from the fact that the 8024 series DOES support FIPS Snooping and will work for FCoE.  DCB can be used for more things than just FCoE.  A recommendation would be to go with the Force 10 S4820 which supports this as well and is comparable to the hardware on the 8100.
Hello!  I'm complete newbie with FCoE, so, please, excuse me for this question. Could you tell is DCB support in 8132 specs means it is suitable for FCoE?  Thank you!
