8 <P>The
<VAR>/etc/cups/snmp.conf
</VAR> file contains several
9 directives that determine how the SNMP printer discovery backend
10 behaves. Each directive is listed on a line by itself followed
11 by its value. Comments are introduced using the number sign (
"#")
12 character at the beginning of a line.
</P>
14 <P>The SNMP backend uses the SNMPv1 protocol to discover network
15 printers, collecting information from the Host MIB along with
16 intelligent port probes to determine the correct device URI and
17 make and model for each printer. Future versions of CUPS will
18 likely support the new Port Monitor MIB as well.
