First thing to do after reading any docs is to contact Cobalt.

Recent kernel, usual snmp... nothing wrong here I would say except
of course that cmu-snmp is discontinued as the home page tells me.

That doesn't mean you can't *view* its configuration doesn't it?
Have a look at /etc/snmpd.conf as this may give you some insight.

Together with "ifconfig -a" and/or "snmpwalk host string 2.2.1.2"
