I think i found something. It's the mib of SNMPv2-MIB : 1.3.6.1.2.1.1 which dosen't work fine in the generator. If I'm more precise and give the oid 1.2.6.2.1.1.1 it works for example. The other oids I put next
* - 1.3.6.1.2.1.2.2 - 1.3.6.1.2.1.31.1.1 - 1.3.6.1.4.1.9.9.109.1.1.1.1.8 - 1.3.6.1.4.1.9.9.13.1.4 - 1.3.6.1.4.1.9.9.13.1.5 - 1.3.6.1.4.1.9.9.48.1.1.1.5 - 1.3.6.1.4.1.9.9.48.1.1.1.6 - 1.3.6.1.4.1.9.9.68.1.2.2.1.2* work without a hitch.
