[SNMP4J] Agent(X)-API status

[Frank Fock]

Hi Gregor,

The work on SNMP4J-Agent API got a little bit stuck during the
past few weeks due to lack of time. I estimate the needed amount
of work to get a fully agent API implementation (including VACM)
from the source available today to be 80-120h.

A demo agent could be available after 40h of additional work.

I have not started yet to implement AgentX subagent functionality,
because this additional component would be based on many functions
provided by the SNMP4J-Agent API.

If you want to implement a AgentX subagent in Java, then you probably
do not need SNMP4J at all. There seem to be at least one free
implementation for AgentX in Java, but I do not know how stable/complete
they are.

The NET-SNMP AgentX implementation has some bugs and limitations
too. so if you specifically want your application to interoperate with a
NET-SNMP master agent, you should make sure that you have the sources
of the AgentX API you use to be able to workaround some pitfalls.

In AgentX++ (AgentX for the C++ agent API AGENT++)  I had to
implement a few workarounds, because the NET-SNMP master agent
handles search ranges not correctly.

Implementing the AgentX functionality on top of SNMP4J-Agent should
be fairly easy. Doing it from scratch could be some effort. How much effort,
mainly depends on your needs.

Hope this helps.

Best regards,
Frank
