       snmp - cups snmp backend

       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.


       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.


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


       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.
