Hi,
I believe what you're looking for is similar to what's mentioned here:
https://community.mcafee.com/message/203078#203078
These can be enabled in the snmpd.conf (Configuration > File Editor > snmpd.conf):
http://www.net-snmp.org/docs/man/snmpd.conf.html
With the following configuration items (append to end of snmpd.conf):
authtrapenable 1
linkUpDownNotifications yes
defaultMonitors yes
"coldStart" and "warmStart" are associated with the "defaultMonitors" option (I believe).
These are not incidents available in MWG, rather native OS SNMP options. Once enabled traps will be sent.
Best Regards,
Jon
