++.TH MASSAGEVENDOR 8
++.SH NAME
++massagevendor \- convert the ethernet vendor codes master list to arpwatch format
++.SH SYNOPSIS
++.na
++massagevendor
++.I vendorfile
++.SH "DESCRIPTION"
++.B massagevendor
++is a program that converts a text file containing ethernet vendor codes
++into a format suitable for use by
++.B arpwatch(8)
++and
++.B arpsnmp(8).
++The input
++.I vendorfile
++is a master text file containing vendor codes. The output
++is sent to
++.I stdout.
++Each line of the
++.I vendorfile
++is expected to have a six digit hexadecimal vendor code
++followed by spaces followed by the name of the manufacturer.
++.LP
++All ethernet devices have a unique identifier which
++includes a vendor code specifying the manufacturer of the
++device. In normal operation
++.B arpwatch(8)
++and
++.B arpsnmp(8)
++use the file
++.I ethercodes.dat
++to report this vendor code.
++.B massagevendor
++is used to generate the
++.I ethercodes.dat
++file from text files containing these vendor codes.
++.LP
++Locations where an ethernet vendor codes master text file
++can be obtained are given below.
