I knew there is a ATM ping, where one can ping ATM devices, which really is not a real ICMP tool but that is another story. I had no clue there is such tool on FCoE devices:

switch# fc?
  fcanalyzer  Start cisco fabric analyzer
  fcdomain    Fcdomain internal command
  fcping      Ping an N-Port
  fctrace     Trace the route for an N-Port.
