[rrd-users] Re: [OT] - Get versus Getnext

Thomas,
Well spotted!
The OID in the response in incremented by 1 for every getnext I do but the
only meaningful result come from a getnext on .16. (which gives .17. in the
response).
I am unable to do a successful GET on any of the OIDs.
Is there something specifically weird with this MIB? Has anyone come across
anything similar?
FYI -
.16. = .1.3.6.1.4.1.311.1.4.1.1.2.1.16.8.72.69.65.84.95.83.81.76
.17. = .1.3.6.1.4.1.311.1.4.1.1.2.1.17.8.72.69.65.84.95.83.81.76

16 != 17 Look again at the response.

Try it with the actual OID you got in the response.
