.SH DESCRIPTION
.B snmptrap
is an SNMP application that uses the SNMP TRAP operation to send
information to a network manager.  One or more object identifiers
(OIDs) can be given as arguments on the command line.  A type and a
value must accompany each object identifier.  Each variable name is
given in the format specified in 
.IR variables(5) .
.PP
When invoked as
.B snmpinform,
or when
.B -Ci
is added to the command line flags of snmptrap, it sends an
INFORM-PDU, expecting a response from the trap receiver,
retransmitting if required.  Otherwise it sends an TRAP-PDU or
TRAP2-PDU.
.PP
If any of the required version 1 parameters, 
.IR enterprise-oid ,
.IR agent ,
and
.I uptime
are specified as empty, it defaults to
.IR "1.3.6.1.4.1.3.1.1 (enterprises.cmu.1.1)" ,
.IR hostname ,
and
.I host-uptime
respectively.
.PP
