[SNMPTRAP(1)](https://www.chedong.com/phpMan.php/man/SNMPTRAP/1/markdown)                                   Net-SNMP                                   [SNMPTRAP(1)](https://www.chedong.com/phpMan.php/man/SNMPTRAP/1/markdown)



## 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 com‐
       mand line.  A type and a value must accompany each object identifier.  Each variable name  is
       given in the format specified in [_variables(5)](https://www.chedong.com/phpMan.php/man/variables/5/markdown)_.

       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:
              **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 '' interfaces.iftable.ifen‐
       try.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)](https://www.chedong.com/phpMan.php/man/snmpcmd/1/markdown)_ manual page in addition to  the
### -Ci
       query as described there.
