Description

The snmptrap utility is an SNMP application that uses the SNMP TRAP operation to send information to a network manager. You can specify one or more object identifiers (OIDs) on the command line. A type and a value must accompany each object identifier. Each variable name must be entered in the format specified in snmp_variables(4).

When invoked as snmpinform, or when you specify the -Ci option to snmptrap, it sends an INFORM-PDU, expecting a response from the trap receiver, and retransmitting if required. Otherwise, it sends a TRAP-PDU or TRAP2-PDU.

If any of the required version 1 parameters—enterprise-oid, agent, and uptime—are specified as empty, they default 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, the following command sends a generic linkUp trap to manager, for interface 1:

# snmptrap -v 1 -c public manager enterprises.spider test-hub 3 0 ''
interfaces.iftable.ifentry.ifindex.1 i 1

Options

The following option is supported:

-Ci
