[AGENT++] A few questions on the master & subagent examples

[michael.carr at bt.com]

Thanks Frank.

I've added that to the command line plus a few other settings that I've
gleamed from the master.cpp code:

./snmpBulk 127.0.0.1 1.3.6.1.4.1.4976.6.1.1 -v3 -P4700 -snunsecureUser
-sl1 -cnsubagent

Which gives something more encouraging but still not quite what I'm
expecting:

I'm still expecting to see the entries in the table as per the code in
subagent.cpp, i.e. "a text" and "another text" plus the two numbers, is
anything else needed on the command line for snmpBulk or do I have it
all wrong?

I also wonder what the engine id is that the snmpBulk doesn't know
about?


The debug output from the master is:

So it does look as though the request is getting through but I'm
concerned with this "-1401" mentioned in both debug traces.

Hi Michael,

the context is ignored because you are not using
SNMPv3 for the request.

Best regards,
Frank
