SNMPTRAP(1) Net-SNMP SNMPTRAP(1) NAME snmptrap, snmpinform - sends an SNMP notification to a manager SYNOPSIS snmptrap -v 1 [COMMON OPTIONS] AGENT enterprise-oid agent generic-trap spe- cific-trap uptime [OID TYPE VALUE]... snmptrap -v [2c|3] [COMMON OPTIONS] [-Ci] AGENT uptime trap-oid [OID TYPE VALUE]... snmpinform -v [2c|3] [COMMON OPTIONS] AGENT uptime trap-oid [OID TYPE VALUE]... DESCRIPTION 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 ac- company 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 re- ceiver, retransmitting if required. Otherwise it sends an TRAP-PDU or TRAP2-PDU. If any of the required version 1 parameters, enterprise-oid, agent, and up- time are specified as empty, it defaults to 1.3.6.1.4.1.3.1.1 (enter- prises.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. The AGENT argument is only embedded in SNMP TRAP PDUs but not in SNMP IN- FORM PDUs. If AGENT is not an empty string, it must be an IPv4 address. This limitation comes from RFC 1157, in which the agent address field is defined as follows: agent-addr NetworkAddress, -- address of object generating trap From RFC 1155: NetworkAddress ::= CHOICE { internet IpAddress } [ ... ] IpAddress ::= [APPLICATION 0] -- in network-byte order IMPLICIT OCTET STRING (SIZE (4)) An example of how to use snmptrap: snmptrap -v 1 -c public manager enterprises.spider test-hub 3 0 '' inter- faces.iftable.ifentry.ifindex.1 i 1 will send a generic linkUp trap to manager, for interface 1. OPTIONS 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. SEE ALSO snmpcmd(1), snmpset(1), variables(5). V5.9.5.2 19 Jun 2003 SNMPTRAP(1)
