DESCRIPTIONSnmptrap 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 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 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:
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 variable. SEE ALSOsnmpcmd(1), variables(5).
