NAME
       snmpd - SNMP agent

SYNOPSIS
       snmpd [-v][-d] [-p interval] [-P port]

   where:
       interval is the polling interval in seconds
       Port is the UDP port number to listen for incoming requests.

DESCRIPTION
       The SNMP agent is implemented as the snmpd command, which is a daemon
       process that services requests from an SNMP network management
       station (NMS).  The agent may be included in the list of daemons in
       the /etc/tcpip.params file to be started and stopped automatically by
       the rc scripts during changes of system run levels.  You can start,
       stop, and configure the agent through sysadm.

       When snmpd is started it disassociates itself from the controlling
       terminal, reads the configuration file, and begins servicing network
       requests.  The agent listens for requests on the UDP port specified
       by the -P option, or if not specified, the number returned by
       getservbyname(3N) for "snmp" which defaults to 161.

       The agent authenticates requests by verifying that the community
       string in the request matches one in the /etc/snmpd.conf file and
       that the level of access matches the type of request.  After
       authentication, the agent accesses or modifies the requested
       information and sends a reply to the originator.

       When the agent is restarted, an interface changes state, or a request
       fails authentication, snmpd sends traps to all the hosts specified in
       the trap records in the /etc/snmpd.conf file.

       Options are:

       -v     Use the -v option to force snmpd to remain attached to the
              controlling terminal and to print additional information about
              the packets received and transmitted.  Use this option to see
              the information exchange between the agent and a management
              station.

       -d     Use the -d option to force snmpd to remain attached to the
              controlling terminal and to print diagnostic messages on
              stderr.  This option is similar to the -v option, however, it
              does not print information about packets received and
              transmitted.  Use this option to see any potential error
              messages without the verbosity of packet exchanges.

       -p interval
              Use this option to set the polling interval (in seconds) that
              snmpd uses to check for changes in the interfaces state.
              Polling is disabled if an interval of 0 is specified, or when
              there are no trap destinations configured in /etc/snmpd.conf.

snmpd(1M)                      TCP/IP 5.4R3.00                     snmpd(1M)


              The default polling interval is 60 seconds, however, no traps
              are configured by default, so polling is disabled by default.

       -P port
              This option causes the agent to listen on UDP port for
              requests.

FILES
       snmpd.conf
              Beginning in DG/UX 5.4R3.00 this file replaces the 3 separate
              configuration files from previous releases.  (snmpd.config,
              snmpd.trapcommunities, and snmpd.communities).  This file
              specifies the communities the agent will recognize, the trap
              destinations, and provides values for a user configurable
              objects.

       /usr/etc/snmp/snmpinfo.dat
              A data file used by the agent and other SNMP commands to
              translate between object ID's and symbolic names.

       /usr/etc/snmp/*.mib.Z
              The /usr/etc/snmp directory contains several files in the
              format <name>.mib.Z.  These files are copies of the MIBs the
              agent supports -- most are Internet standard RFCs, however,
              there are some enterprise MIBs.  The agent implements the HP-
              UNIX MIB for the filesystem and process table information.
              The DGC MIB contains management information specific to DG/UX
              or AViiON hardware and printer management information.  The
              files have been compressed via compress(1) and must be
              uncompressed before they can be used.  After uncompressing the
              files they are ready for use with your management station
              software.

DIAGNOSTICS
       If their are errors parsing the command line or the -v or -d options
       are specified, output is sent to stdout and stderr, otherwise, all
       output is sent to syslogd.  Fatal or critical messages are logged at
       syslog level LOG_WARNING, other messages are logged at level
       LOG_INFO.
