You should not only use the OID but also the instance.

The instance to use is 2 (this info seen from the original target line)
so the complete variable to poll is 1.3.6.1.2.1.2.2.1.13.2 etcetera.

> Target[128.243.3.1.2]: ifInDiscards.1&ifOutDiscards.1:public@128.243.3.1

You should only have one target line (for this interface) and can use either
one of those two.

Remember: The instance is 2, not 1 !
