NAME

       snmp - cups snmp backend (deprecated)


SYNOPSIS

       /usr/lib/cups/backend/snmp ip-address-or-hostname
       /usr/libexec/cups/backend/snmp ip-address-or-hostname
       lpinfo -v --include-schemes snmp


DESCRIPTION

       The DEPRECATED CUPS SNMP backend provides legacy discovery and
       identification of network printers using SNMPv1.  When used for
       discovery through the scheduler, the backend will list all printers
       that respond to a broadcast SNMPv1 query with the "public" community
       name.  Additional queries are then sent to printers that respond in
       order to determine the correct device URI, make and model, and other
       information needed for printing.

       In the first form, the SNMP backend is run directly by the user to look
       up the device URI and other information when you have an IP address or
       hostname.  This can be used for programs that need to configure print
       queues where the user has supplied an address but nothing else.

       In the second form, the SNMP backend is run indirectly using the
       lpinfo(8) command.  The output provides all printers detected via SNMP
       on the configured broadcast addresses.  Note: no broadcast addresses
       are configured by default.


ENVIRONMENT

       The DebugLevel value can be overridden using the CUPS_DEBUG_LEVEL
       environment variable.  The MaxRunTime value can be overridden using the
       CUPS_MAX_RUN_TIME environment variable.


FILES

       The SNMP backend reads the /usr/local/etc/cups/snmp.conf configuration
       file, if present, to set the default broadcast address, community name,
       and logging level.


NOTES

       The CUPS SNMP backend is deprecated and will no longer be supported in
       a future version of CUPS.


CONFORMING TO

       The CUPS SNMP backend uses the information from the Host, Printer, and
       Port Monitor MIBs along with some vendor private MIBs and intelligent
       port probes to determine the correct device URI and make and model for
       each printer.
