GET Command Generator

Send a SNMP GET request

This script performs similar to the following Net-SNMP command:

$ snmpset -v1 -c public -ObentU 195.218.195.228 1.3.6.1.2.1.1.1.0

Requires Trollius framework!

from pysnmp.carrier.asyncio.dgram import udp
from pysnmp.entity.rfc3413.asyncio import cmdgen
from pysnmp.entity import engine, config
import trollius

# Get the event loop for this thread
loop = trollius.get_event_loop()

# Create SNMP engine instance
snmpEngine = engine.SnmpEngine()

#
# SNMPv2c setup
#

# SecurityName <-> CommunityName mapping
config.addV1System(snmpEngine, 'my-area', 'public')

# Specify security settings per SecurityName (SNMPv1 - 0, SNMPv2c - 1)
config.addTargetParams(snmpEngine, 'my-creds', 'my-area', 'noAuthNoPriv', 0)

#
# Setup transport endpoint and bind it with security settings yielding
# a target name
#

# UDP/IPv4
config.addTransport(
    snmpEngine,
    udp.domainName,
    udp.UdpTransport().openClientMode()
)
config.addTargetAddr(
    snmpEngine, 'my-router',
    udp.domainName, ('195.218.195.228', 161),
    'my-creds'
)
