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 manufacturing 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.
