OUI(8)                                                     OUI(8)

     NAME
          etheroui, wwnoui - OUI Parsing

     SYNOPSIS
          etheroui [ mac ... ]
          wwnoui [ wwn ... ]

     DESCRIPTION
          These commands convert common strings containing an embedded
          IEEE Organizationally Unique Identifier (OUI) to the manu-
          facturing organization's name.  Etheroui accepts MAC
          addresses while wwnoui accepts World Wide Names (WWNs).

     EXAMPLES
          Often it is helpful in determining the source of unknown
          packets on a network to know the manufacturer.  Given these
          error messages in /sys/log/ipboot, etheroui can be used to
          narrow down the list of suspect equipment.

               ; tail -100 /sys/log/ipboot | grep 'no binding'
