NAME

   snmp - cups snmp backend

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  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 /etc/cups/snmp.conf configuration file, if
   present, to set the default  broadcast  address,  community  name,  and
   logging level.

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.
