 It seems good, I'm working on it to confirm.

If you want to use a non-default context, then yes - this needs to be configured.

See the FAQ entry
    How can I register a MIB module in a different (SNMPv3) context?
        http://www.net-snmp.org/wiki/index.php/FAQ:Coding_22

and the Wiki page
    http://www.net-snmp.org/wiki/index.php/Snmpd_proxy

for details.

Those lines belong in the file 'snmp.conf'
They are used for *client* side configuration, not the agent.

Which is supplying most of these values explicitly, and does *not*
specify a context.   So you'll be using the default (blank) context.

Exactly as above

Because you haven't configured anything for this context.

Bottom line - why are you trying to use contexts anyway?
It's not necessary in most cases.
