[SNMP4J] Help with TestAgent!!

[Muralidharan Narayanan]

I downloaded the latest library for SNMP4J and SNMP4J-agent. I created a
project for running the TestAgent in Eclipse IDE. I am sure somebody has an
explanation for this below issues. I am sorry if I am revisiting this again.

- Upon running the example as is, I see the following ouput. But the INFORM
(trap) for COLDSTART is not coming to the SNMP manager running on the same
PC that this "TestAgent" is running.

- I was running the SNMP manager MIBExplorer with SNMPv2c versus TestAgent
with SNMPv3 - Didn't see the INFORM. I also tried SNMP manager in
MIBExplorer with SNMPv3 (SHADES user added) versus TestAgent with SNMPv3 -
Didn't see INFORM either.

- However, I am able to SEND & RECEIVE "GET/GET-RESPONSE" messages from the
SNMP manager on the same PC. I sent GET requests for MIB obj
snmpv2MIB.SysUpTime (1.3.6.1.2.1.1.3) and was able to get response. This
worked only with manager on v2c only, not woring for manager on v3 though.

- If I strip down all SNMPv3 references from TestAgent and run it with SNMP
manager on v2c, I receive the COLDSTART trap but I am unable to SEND &
RECEIVE "GET/GET-RESPONSE" messages

Does anybody know why?

Thanks for response
