i means that i will cut down the net-snmp snmpd to a minimal agent supporting 
SNMPv1/v2c/v3/AgentX 
and my enterprise-specific MIB.  the MIBs implemetented by mini-agent are all 
MIBs that i need?

agentxMIB described as rfc 2742 are not impletemented by net-snmp-5.3.0.1, 
right?
will it be impletemented in the recent future?

yeah, i hope someone else have the experience about that ....

considering this case:
        there are so many devices runing a subagent cutted down from net-snmp 
snmpd , supporting the minimal 
MIBs and enterprise-specific MIB,  and registering to the same master agent.

        the master agent will dispatch all my SNMP request for the speficic 
subagent to the proper subagent.
because all the MIB regions registered by the subagent have a default priority 
so i have to gather all 
the groups of scalar objects into tables.

maybe i can have the following choice:
the subagent will do not request index allocation for rows in the table of the 
enterprise-specific MIB,
it will would simply register the region defining that row's object instances 
without allocating index 
values described as the rfc 2741 section 7.1.4.2.2.

but, can i do that?  and how?

i hope i have expressed myself clearly. thank you.
