A table may not contain another table or any instances other
than columnar objects.

Scalar instances must have an OID that is composed
of the scalar object class OID and a .0 suffix!

Use 1.3.6.1.2.1.2.2.1.1.0 and 1.3.6.1.2.1.2.2.1.6.1.0
and make sure that those OIDs are not registered elsewhere
in the agent.

I think you are mis leaded here. Such an agent would
violate basic SNMP rules.
