Hi,

I just took over SNMPv2 agent that should be upgraded to V3 by this month. Following is some more details about current v2c agent:
  - working on RedHat enterprise Linux 6
  - Built in C++
  - supports SNMPv2c with trap
  - supports more than 200 proprietary MIBs
  - All codes were created by previous programmer without using any open source.
  - Parsing every SNMP packet and calling appropriate handlers depends on OID. (like general agent)

I started to learn net-SNMP and how to use it to support V3, but still have had no idea. Is it a idiot question asking the easiest and the fastest way to build v3 with existing v2c agent? Welcome any comments.

 

There are a lot of differences between v2c and v3.

Adding v3 capability to an existing v2c agent would not be trivial.
Gads, even thinking about it makes me sigh.

The BER encoding would be the same but there is so much more going on in v3.

In my opinion, your time would be better spent learning net-snmp or if your company has more money and less time going to someone like SNMP Research.

Thanks, bnorton916.

Good luck.
