You'd need to change the value too and it all must be done within the agent.

Well, "broken" was probably a bit strong.  Fortunately the agent is
doing the right thing and accepting packets that aren't properly
encoded.

The GETNEXT packets coming from SnmpMonitor shouldn't include a value
but it does.  It's including the value it pulled from the last answer
and re-inserting that into the next request which it technically
shouldn't do.
