NAME

       snmp_trapsnd - A program that sends SNMPv1 and SNMPv2 traps

SYNOPSIS

       /usr/sbin/snmp_trapsnd  enterprise  agent_addr  generic specific timeticks [-v version] [-c community] [-h host] [-p port] [-tcp] [variable
       [type value]]

OPTIONS

       Specifies the type of message in which to send the PDU. The default version is SNMPv1.  Use 2c to specify  that	the  PDU  be  sent  in	an
       SNMPv2C	message.   Specifies the host name or dot-formatted IP address of the destination node to receive the trap message.  If no host is
       specified, the trap is sent to the loopback interface.  Causes a hexadecimal dump of the encoded packet to be sent  to  stdout.	 Specifies
       that the TCP transport be used instead of the UDP transport.  If a connection cannot be established, the program silently sends the trap to
       the standard transport address (UDP 162).  Specifies the port number on the destination host to which this message is sent.  The default is
       162, the well-known SNMP trap port.  Specifies the community string used to send the trap.  The default is public.

OPERANDS

       For  SNMPv1  traps,  this is the enterprise object identifier, in dot string notation, on whose behalf the trap is being sent (for example,
       1.3.6.1.4.1.232).

	      For SNMPv2 traps (specified with the -v 2c option), this represents the value of snmpTrapOID.0.  For an  SNMPv2  enterprise-specific
	      trap,  this is typically a concatenated string containing the enterprise OID, 0 (zero), and a single digit.  See the generic parame-
	      ter table.  The hostname or IP address of the entity on whose behalf the trap is being generated (the agent-addr	field  in  the	V1
	      trap  PDU).  The special name local reports the host on which this program is running.  This value is ignored if the -v 2c option is
	      present.	The generic trap identifier.  This is a non-zero number.  The following table summarizes the trap IDs:

	      ------------------------------------------------------------------------
	      Description	      V1 generic Value	  V2 enterprise Value
	      ------------------------------------------------------------------------
	      coldStart 	      0 		  1.3.6.1.6.3.1.1.5.1
	      warmStart 	      1 		  1.3.6.1.6.3.1.1.5.2
	      linkDown		      2 		  1.3.6.1.6.3.1.1.5.3
	      linkUp		      3 		  1.3.6.1.6.3.1.1.5.4
	      authenticationFailure   4 		  1.3.6.1.6.3.1.1.5.5
	      egpNeighborLoss	      5 		  1.3.6.1.6.3.1.1.5.6
	      enterpriseSpecific      6 		  enterprise.0.x
	      ------------------------------------------------------------------------

	      If the -v 2c option is present, this parameter is ignored.  Specifies the enterprise-specific trap number.  A value must be present,
	      but  is  ignored	if the -v 2c option is present or if generic is a value other than 6.  Specifies the relative time associated with
	      the generation of this trap message.  This is the number of TIMETICKS (1/100 of a second) since the  sending  SNMP  entity  started.
	      Specifies  a  list of MIB variables to be included in the trap message.  See snmp_request(8) for information on specifiying SNMP MIB
	      variables on the command line.

DESCRIPTION

       The snmp_trapsnd program encodes an SNMPv1 Trap protocol data unit (PDU) (see RFC 1215) or a SNMPv2 Trap PDU (see RFC 1905)  into  an  SNMP
       message, and sends it to the specified host(s).	All data fields in the trap PDU can be specified in the run-time arguments.

       SNMPv1  traps  are uniquely identified by the combination of enterprise, generic, and specific operands.  SNMPv2 traps are uniquely identi-
       fied by the value of snmpTrapOID.0 in the enterprise operand.

RESTRICTIONS

       The use of this command should be limited.  SNMP traps should be sent rarely, when significant state changes occur on a managed node.
