# Common notifications

## SNMPv1 TRAP with defaults

Send SNMPv1 TRAP through unified SNMPv3 message processing framework using the following options:

- SNMPv1

- with community name ‘public’

- over IPv4/UDP

- send TRAP notification

- with Generic Trap #1 (warmStart) and Specific Trap 0

- with default Uptime

- with default Agent Address

- with Enterprise OID 1.3.6.1.4.1.20408.4.1.1.2

- include managed object information ‘1.3.6.1.2.1.1.1.0’ = ‘my system’

Functionally similar to:

$ snmptrap -v1 -c public demo.snmplabs.com 1.3.6.1.4.1.20408.4.1.1.2 0.0.0.0 1 0 0 1.3.6.1.2.1.1.1.0 s “my system”

    def run():
        snmpEngine = SnmpEngine()
        errorIndication, errorStatus, errorIndex, varBinds = yield from sendNotification(

                ('1.3.6.1.2.1.1.1.0', OctetString('my system'))
            )
        )

        if errorIndication:
            print(errorIndication)
