SYNOPSIS
snmptrap -v 1 [-Ci] [common arguments] enterprise-oid
agent generic-trap specific-trap uptime [objectID type
value]...

DESCRIPTION
Snmptrap is an SNMP application that uses the TRAP Request
to send information to a network manager. One or more
fully qualified object identifiers can be given as argu
ments on the command line. A type and a value must accom
pany each object identifier. Each variable name is given
in the format specified in variables(5).
When invoked as snmpinform, or when -Ci is added to the
command line flags of snmptrap, it sends an INFORM-PDU,
expecting a response from the trap receiver, retransmit
ting if required. Otherwise it sends an TRAP-PDU or
TRAP2-PDU.
If any of the required version 1 parameters, enterprise-
oid, agent, and uptime are specified as empty, it defaults
to 1.3.6.1.4.1.3.1.1 (enterprises.cmu.1.1), hostname, and
host-uptime respectively.
The type is a single character, one of:
i INTEGER
u UNSIGNED
c COUNTER32
s STRING
x HEX STRING
d DECIMAL STRING
n NULLOBJ
o OBJID
t TIMETICKS
a IPADDRESS
b BITS
For example
snmptrap -v 1 manager public enterprises.spider test-hub 3
0 '' interfaces.iftable.ifentry.ifindex.1 i 1
will send a generic link-up trap to manager, for interface
1.

If the network entity has an error processing the request
packet, an error packet will be returned and a message
will be shown, helping to pinpoint in what way the request
was malformed. If there were other variables in the
request, the request will be resent without the bad vari
able.
