FW: [SNMP4J] snmp get with partial indexes

[Ori Liel]

Unfortunately I have no control over the SNMP agent...

Can you think of another way to get rows according to a subset of index
values? 

Thanks.

Can you push back on the protocol version restriction?  In this day  
and age there's really no excuse for not supporting at least v2c.

The only workaround I can think of is to use a set operation to tell  
the agent the constraints you wish on index1 and index2, and have the  
agent construct a "shadow" table that mirrors the original but  
includes only the set of rows described by the last constraints set in  
place.  This is far from elegant, but it might work.
