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 (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 which are handled in the same way as the snmpset command. For example: 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.
