Re: [snmpsim-users] snmpbulkget outpu in version 0.2.2

[Ilya E. <il...@gl...>]

Hi Yateen,

First thing that come to mind is that you may not have all the OIDs in your SQL DB. Could you make sure the following table contains OIDs you expect to see in response:

select oid from snmprec order by oid

If that does not explain the problem, could you send me the sqlite .db file in question?

Does this issue show up when using plain .snmprec, not SQL DB?
