Re: [pysnmp-users] bulkcmd works in old example code, but not in new example.

Hi Gee,

I think with both old and new code you should pass OID in either of the two forms:

- as a string (1.3.6.1.1…) or
- tuple of integers (1, 3, 6, 1, …) e,g,:

                         ObjectType(ObjectIdentity((1, 3, 6, 1, 2, 1, 17, 4, 3, 1, 1))),

Note extra parentheses around the numbers.
