+.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.
