So, first this shell command :
snmpget -v 2c -c private 10.0.0.1 rbQoSProfileType.25
and the result :
RAINBOW-SERVICES-MIB::rbQoSProfileType.25 = INTEGER: rbRT(1)
Then :
snmpget -v 2c -c private 10.0.0.1 rbQoSProfileType.24
and the result :
Error in packet
> Reason: (genError) A general failure occured
> Failed object: RAINBOW-SERVICES-MIB::rbQoSProfileType.24
>
But I know why there is an error here. In fact, in the table the index goes
from 1 to 17 and then skip to 25. So there is no entry for 18 to 24. Here is
the same shell command as above but with the 17th index :
snmpget -v 2c -c private 10.0.0.1 rbQoSProfileType.24
>
and the result :
RAINBOW-SERVICES-MIB::rbQoSProfileType.17 = INTEGER: rbBE(3)
Then :
snmpgetnext -v 2c -c private 10.0.0.1 rbQoSProfileType.17
>
and the result :
RAINBOW-SERVICES-MIB::rbQoSProfileType.25 = INTEGER: rbRT(1)
>
These shell commands work, so I continue with my script (and I replace 24 by
17, as explained above) :
import netsnmp
>
> profileNb = "17"
> qosType = "0"
> value = "rbQoSProfileType"
>
> oid = netsnmp.Varbind(value, profileNb, qosType)
> result = netsnmp.snmpget(oid, DestHost = "10.0.0.1", Community = "private",
> Version = 2)
> print("%s") %(result)
>
And this script crashes. It also gives segmentation fault.
Now with GETNEXT :
import netsnmp
>
> profileNb = "17"
> qosType = "0"
> value = "rbQoSProfileType"
>
> oid = netsnmp.Varbind(value, profileNb, qosType)
> result = netsnmp.snmpgetnext(oid, DestHost = "10.0.0.1", Community =
> "private", Version = 2)
> print("%s") %(result)
>
The result is still the same, it crashes with segmentation fault.
