19 snmptrap is an SNMP application that uses the SNMP TRAP operation to
20 send information to a network manager. One or more object identifiers
21 (OIDs) can be given as arguments on the command line. A type and a
22 value must accompany each object identifier. Each variable name is
23 given in the format specified in variables(5).
24
25 When invoked as snmpinform, or when -Ci is added to the command line
26 flags of snmptrap, it sends an INFORM-PDU, expecting a response from
27 the trap receiver, retransmitting if required. Otherwise it sends an
28 TRAP-PDU or TRAP2-PDU.
29
30 If any of the required version 1 parameters, enterprise-oid, agent, and
31 uptime are specified as empty, it defaults to 1.3.6.1.4.1.3.1.1 (enter‐
32 prises.cmu.1.1), hostname, and host-uptime respectively.
33
34 The TYPE is a single character, one of:
35 i INTEGER
36 u UNSIGNED
37 c COUNTER32
38 s STRING
39 x HEX STRING
40 d DECIMAL STRING
41 n NULLOBJ
42 o OBJID
43 t TIMETICKS
44 a IPADDRESS
45 b BITS
46 which are handled in the same way as the snmpset command.
47
48 The AGENT argument is only embedded in SNMP TRAP PDUs but not in SNMP
49 INFORM PDUs. If AGENT is not an empty string, it must be an IPv4 ad‐
50 dress. This limitation comes from RFC 1157, in which the agent address
51 field is defined as follows:
52
53 agent-addr NetworkAddress, -- address of object generating trap
54
55 From RFC 1155:
56
57 NetworkAddress ::=
58 CHOICE {
59 internet IpAddress
60 }
61 [ ... ]
62 IpAddress ::=
63 [APPLICATION 0] -- in network-byte order
64 IMPLICIT OCTET STRING (SIZE (4))
65
66 An example of how to use snmptrap:
67
68 snmptrap -v 1 -c public manager enterprises.spider test-hub 3 0 '' in‐
69 terfaces.iftable.ifentry.ifindex.1 i 1
70
71 will send a generic linkUp trap to manager, for interface 1.
72
74 snmptrap takes the common options described in the snmpcmd(1) manual
75 page in addition to the -Ci option described above. Note that snmptrap
76 REQUIRES an argument specifying the agent to query as described there.
77
79 snmpcmd(1), snmpset(1), variables(5).
