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 specific-trap up-
time [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 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 re-
quired. Otherwise it sends an TRAP-PDU or TRAP2-PDU.
If any of the required version 1 parameters, enterprise-oid, agent, and uptime are speci-
fied 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:
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 '' 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.
