I have the same question - no trap is sent when the ethernet is enabled or disabled by the commands "ifdown eth0" & "ifup eth0" issued through serial port (console).

# cat /usr/local/share/snmp/snmpd.conf
rwuser "admin" priv
authtrapenable 1
trapcommunity  public
trap2sink      172.20.11.72

iquerySecName _internal
rouser        _internal

# Active the standard monitoring entries
defaultMonitors         yes
linkUpDownNotifications yes

I had done
createUser  _internal MD5 somejunk
[ in the file /var/net-snmp/snmpd.conf]


# cat /var/net-snmp/snmpd.conf
#
# net-snmp (or ucd-snmp) persistent data file.
