tag_summary = "Attempts to enumerate network interfaces through SNMP.

This script can also be run during Nmap's pre-scanning phase and can attempt to add the SNMP
server's interface addresses to the target list.  The script argument 'snmp-
interfaces.host' is required to know what host to probe.  To specify a port for the SNMP
server other than 161, use 'snmp-interfaces.port'.  When run in this way, the script's
output tells how many new targets were successfully added.


SYNTAX:

snmp-interfaces.port:   The optional port number corresponding
to the host script argument.  Defaults to 161.



snmpcommunity:  The community string to use. If not given, it is
''public'', or whatever is passed to 'buildPacket'.


snmp-interfaces.host:   Specifies the SNMP server to probe when
running in the 'pre-scanning phase'.";
