Hi Magnus,
Thank you very much for your suggestion, however, using proxy directive to
forward to my current SNMPv1 is not acceptable for our project. This agent
is just a module (a part) in our big project. I need to modify that part of
the code. Do you know any easy to use library for vxworks? I don't really
need a full blow library like current net-snmp.
