NAME
       snmpd - SNMP agent

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

   where:
       interval is the polling interval in seconds

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 also can
       start or stop the agent through sysadm.

       When snmpd is started it disassociates itself from the controlling
       terminal, reads the configuration files, and begins servicing network
       requests.  The agent listens for requests on the UDP port returned by
       getservbyname(3N) for "snmp" which defaults to 161.

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

       When the agent determines it has been restarted, or when an interface
       changes state, or when a request fails authentication it sends traps
       to all the hosts specified in /etc/snmpd.trapcommunities 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.  An
              interval of 0 or an empty /etc/snmpd.trapcommunities file
              will disable polling.  The default polling interval is 60
              seconds.

FILES
       snmpd.config
              Use this file to override default values for objects that are
              machine dependent.

       snmpd.communities
              Use this file to define the list of community strings, host
              addresses, and access levels recognized by the agent.

       snmpd.trapcommunities
              Use this file to define the list of communities, host
              addresses, and port numbers where the agent sends traps.

DIAGNOSTICS
       If the -v or -d options are specified output is sent to stdout and
       stderr, otherwise, all output is sent to syslogd.
