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 /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.
