To enable SMUX protocol support, please configure net-snmp
like below.
% configure --with-mib-modules=smux
After compile and install net-snmp, you will need to configure
smuxpeer. I'm now using configuration shown below. This means SMUX client
connects to MIB 1.3.6.1.6.3.1 with password test.
/usr/local/share/snmp/snmpd.conf
