HP SNMP Traps signalled every 10 seconds for a NIC

I'm trying to setup SNMP traps on my HP DL160 G6 (Xenserver) to notify me whenever I have issues with the server.

Following suggestions from this serverfault post, I've installed the HP SNMP agents and configured my cma.conf to email me whenever I have an SNMP trap generated. To test it out, I unplugged a secondary NIC.

My problem is that instead of just getting a single trap indicating that the NIC was disconnected or reconnected, I get traps generated every 10secs indicating that the link is down or up.

I also installed the HP System Management web interface, but can't seem to find how to configure the NIC agent to stop sending traps every 10secs and only trap on state change.

Is this possible?

With the SNMP agent (cmanicd) enabled, I get the following in /var/log/messages:
