NAME
snmptrap, snmpinform - sends an SNMP notification to a manager
SYNOPSIS
snmptrap -v 1 [COMMON OPTIONS] AGENT enterprise-oid agent generic-trap
specific-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 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 (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
INFORM PDUs. If AGENT is not an empty string, it must be an IPv4 ad-
dress. 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 '' in-
terfaces.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.
