Python SNMP GetBulk - Multiple OIDs

python snmp pysnmp
sonofdelphi picture sonofdelphi · May 2, 2011 · Viewed 8.4k times · Source

I need to use PySNMP's GetBulk implementation to query for a list of Table OIDs. I was able to get it to query for 1 Table OID, but unable to get it to read the Table OIDs from a list. What am I doing wrong? Please help. 

from pysnmp.entity.rfc3413.oneliner import cmdgen  

errorIndication, errorStatus, errorIndex, \  
varBindTable = cmdgen.CommandGenerator().bulkCmd(  
            cmdgen.CommunityData('test-agent', 'public'),  
            cmdgen.UdpTransportTarget(('localhost', 161)),  
            0,   
            25,  
            (1,3,6,1,2,1,4,20) # ipAddrTable OID . This works fine.
            # I also want to query .1.3.6.1.2.1.4.21 ipRouteTable in the same command  
            # Putting is as ( (1,3,6,1,2,1,4,20), (1,3,6,1,2,1,4,21) )  gives an error
        )

if errorIndication:
   print errorIndication
else:
    if errorStatus:
    print '%s at %s\n' % (
        errorStatus.prettyPrint(),
        errorIndex and varBindTable[-1][int(errorIndex)-1] or '?'
        )
else:
    for varBindTableRow in varBindTable:
        for name, val in varBindTableRow:
            print '%s = %s' % (name.prettyPrint(), val.prettyPrint())

I think this is what you want...

errorIndication, errorStatus, errorIndex, \
varBindTable = cmdgen.CommandGenerator().bulkCmd(
            cmdgen.CommunityData('test-agent', 'public'),
            cmdgen.UdpTransportTarget(('localhost', 161)),
            0,
            25,
            (1,3,6,1,2,1,4,20), # ipAddrTable
            (1,3,6,1,2,1,4,21), # ipRouteTable
        )

EDIT

Using

[mpenning@hotcoffee ~]$ cat sn_GetBulk.py 
from pysnmp.entity.rfc3413.oneliner import cmdgen  

errorIndication, errorStatus, errorIndex, \
varBindTable = cmdgen.CommandGenerator().bulkCmd(  
            cmdgen.CommunityData('test-agent', 'public'),  
            cmdgen.UdpTransportTarget(('192.168.49.49', 161)),  
            0, 
            25, 
            (1,3,6,1,2,1,4,20), # ipAddrTable OID . This works fine.
            (1,3,6,1,2,1,4,21), # ipRouteTable
            (1,3,6,1,2,1,4,22), # ipNetToMediaTable
        )

if errorIndication:
   print errorIndication
else:
    if errorStatus:
        print '%s at %s\n' % (
            errorStatus.prettyPrint(),
            errorIndex and varBindTable[-1][int(errorIndex)-1] or '?'
            )
    else:
        for varBindTableRow in varBindTable:
            for name, val in varBindTableRow:
                print '%s = %s' % (name.prettyPrint(), val.prettyPrint())
