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 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, retransmitting 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 188.8.131.52.184.108.40.206.1
(enterprises.cmu.1.1), hostname, and host-uptime respectively.
The TYPE is a single character, one of:
x HEX STRING
d DECIMAL STRING
which are handled in the same way as the snmpset command.
snmptrap -v 1 -c public manager enterprises.spider test-hub 3 0 '' interfaces.iftable.ifentry.ifindex.1 i 1
will send a generic linkUp trap to manager, for interface 1.
snmptrap takes the common options described in the snmpcmd(1) manual page in addition to the -Ci option described above. Note that
snmptrap REQUIRES an argument specifying the agent to query as described there.
