My apologies, I didn't include any debugging from /usr/sfw/sbin/snmpd,
/var/log/snmpd.log.
Its attached, added #####TJM to note areas of concern, lines 283 and 403.
I had to resend the request so sequence numbers are not the same between
traces, but it does illustrate the problem, snmpd gets a response from tree
353, responds 326.

Hi Ganesh,
The snmp configuration is basically the default. Initially, snmpdx.reg was
not modified until a problem was noticed, next step was adding our agent
definitions per the migration note found at Sun.
I didn't attach the agent because to see the issue you need an ATM nic
adapter.
I have attached my solaris specific code with the SSA calls to open the
agent and register subtrees. You may notice some odd looking code to cater
to a case where we have 2 subagents running with some printf("TJM...")
messages. I just wanted to isolate some things. I hope this doesn't muddle
the discussion.
I have attached snmpd.conf and snmpdx.reg.
The subagent was developed quite some time ago.
I have also attached the debug output from /usr/lib/snmp/snmpd for a getnext
request to show the problem. In test.txt I have annoted some stuff with
lines that being ####. At the end I have a trace of the packets
send/received by the snmp requestor.
At the end of the my agent responds in tree 353, but the requestor receives
a packet in the 326 tree.
Thank you for your time!
Tom

Hi Tom,
From solaris 10 onwards SMA(System Management Agent) is the default snmp
agent.
SEA will work as subagent to SMA. If you want to configure SEA alone or
along with SMA, both are possible.
As per your configuration SEA agent should work. Can you please send us your
configuration files and the agent which you are configuring. Are you using
SEA SDK for developing your agent. Please let me know.
You can also post a query to [EMAIL PROTECTED] or [EMAIL PROTECTED] for
help.
Regards
Ganesh.
