You should not configure/send SNMP Traps to ClearPass, except if you deploy OnConnect for switches that don't support RADIUS. And if you have switches that don't support RADIUS, I would rather look for different switches as they must be really old.
If you want to deploy OnConnect, and see the traps being denied, it may be best to work with Aruba Support.

Is there any fix on this? why does we need to report mac change to clearpass? something to do with endpoint update?

Hi,
I'm trying to setup ClearPass to receive SNMP trap messages from our Cisco switches for MAC Address changes on switch ports. We are using SNMPv3 on all our switches and we are using authNoPriv with SHA as out auth protocol.
In ClearPass we have the correct SNMPV3 Trap username, Auth Protocol and Auth key set correctly with Encryption disabled and no Encryption protocol set. When I go to test sending traps to ClearPass all I can see are Warnings under Monitoring -> Even Viewer. For every trap that is sent from any switch I get this warning message:
Ignore bad SNMP trap from <SWITCH_IP>/64604. Error=Unknown security name (1404)
I've tried looking online and in the CPPM User guide for this event message and error code, but I've been unsuccessful. I'm not sure where to look next or what to do.
Thanks!
