"""
Sequence Of GET's
+++++++++++++++++
Send two SNMP GET requests in a row using the following options:
* with SNMPv2c, community name "public"
* over IPv4/UDP
* to an Agent at demo.snmplabs.com:161
* for IF-MIB::ifInOctets.1 and IF-MIB::ifOutOctets.1 MIB objects
* with MIB lookup enabled
Use a queue of MIB objects to query.
The next() call is used to forward Python iterator to the position where it
could consume input
Functionally similar to:
| $ snmpget -v2c -c public demo.snmplabs.com IF-MIB::ifInOctets.1
"""#
from pysnmp.hlapi.v1arch import *
queue = [
[ObjectType(ObjectIdentity('IF-MIB', 'ifInOctets', 1))],
[ObjectType(ObjectIdentity('IF-MIB', 'ifOutOctets', 1))]
]
iterator = getCmd(
SnmpDispatcher(),
CommunityData('public'),
UdpTransportTarget(('demo.snmplabs.com', 161)),
lookupMib=True
)
next(iterator)
while queue:
errorIndication, errorStatus, errorIndex, varBinds = iterator.send(queue.pop())
if errorIndication:
print(errorIndication)
elif errorStatus:
print('%s at %s' % (errorStatus.prettyPrint(),
errorIndex and varBinds[int(errorIndex) - 1][0] or '?'))
else:
for varBind in varBinds:
print(' = '.join([x.prettyPrint() for x in varBind]))
