It is a well documented and pervasive protocol, +used in all networks worldwide. + +As an API offering, the only way to interact with **trapd** is +to send traps that conform to the industry standard specification +(RFC1215 - available at https://tools.ietf.org/html/rfc1215 ) to a +running instance. To accomplish this, you may: + +1. Configure SNMP agents to send native traps to a SNMPTRAP instance. + In SNMP agent configurations, this is usually accomplished by + setting the "trap target" or "snmp manager" to the IP address + of the running VM/container hosting SNMPTRAP. + +2. Simulate a SNMP trap using various freely available utilities. Two + examples are provided below, *be sure to change the target + ("localhost") and port ("162") to applicable values in your + environment.* + +NetSNMP snmptrap +---------------- + +One way to simulate an arriving SNMP trap is to use the Net-SNMP utility/command snmptrap. +This command can send V1, V2c or V3 traps to a manager based on the parameters provided. + +The example below sends a SNMP V1 trap to the specified host. Prior to running this command, export +the values of *to_ip_address* (set it to the IP of the VM hosting the ONAP trapd container) and *to_port* (typically +set to "162"): + + ``export to_ip_address=192.168.1.1`` + + ``export to_port=162`` + +Then run the Net-SNMP command/utility: + + ``snmptrap -d -v 1 -c not_public ${to_ip_address}:${to_portt} .1.3.6.1.4.1.99999 localhost 6 1 '55' .1.11.12.13.14.15 s "test trap"`` + +.. note:: + + This will display some "read_config_store open failure" errors; + they can be ignored, the trap has successfully been sent to the + specified destination. + +python using pysnmp +------------------- + +Another way to simulate an arriving SNMP trap is to send one with the python *pysnmp* module. (Note that this +is the same module that ONAP trapd is based on). + +To do this, create a python script called "send_trap.py" with the following contents. You'll need to change the +target (from "localhost" to whatever the destination IP/hostname of the trap receiver is) before saving: + +.. code-block:: python + + from pysnmp.hlapi import * + from pysnmp import debug + + # debug.setLogger(debug.Debug('msgproc')) + + errorIndication, errorStatus, errorIndex, varbinds = next(sendNotification(SnmpEngine(), + CommunityData('not_public'), + UdpTransportTarget(('localhost', 162)), + ContextData(), + 'trap', + [ObjectType(ObjectIdentity('.1.3.6.1.4.1.999.1'), OctetString('test trap - ignore')), + ObjectType(ObjectIdentity('.1.3.6.1.4.1.999.2'), OctetString('ONAP pytest trap'))]) + ) + + if errorIndication: + print(errorIndication) + else: + print("successfully sent trap") + +To run the pysnmp example: + + ``python ./send_trap.py`` |
