NAME

6       massagevendor  -  convert the ethernet vendor codes master list to arp‐
7       watch format
8

SYNOPSIS

10       massagevendor vendorfile
11

DESCRIPTION

13       massagevendor is a program that converts a text file containing ether‐
14       net vendor codes into a format suitable for use by arpwatch(8) and arp‐
15       snmp(8).  The input vendorfile is a master text file containing vendor
16       codes. The output is sent to stdout.  Each line of the vendorfile is
17       expected to have a six digit hexadecimal vendor code followed by spaces
18       followed by the name of the manufacturer.
19
20       All ethernet devices have a unique identifier which includes a vendor
21       code specifying the manufacturer of the device. In normal operation
22       arpwatch(8) and arpsnmp(8) use the file ethercodes.dat to report this
23       vendor code.  massagevendor is used to generate the ethercodes.dat file
24       from text files containing these vendor codes.
25
26       Locations where an ethernet vendor codes master text file can be
27       obtained are given below.
