    Hi All,

    Just double-check if these details below pertaining SNMP query probe are true,

    especially under Remarks column, where it says 'can be triggered by SNMP trap'.

    This table comes from my solution architect.

    No Profiling Methods Active / Passive Pre-requisite from Medical Device Remarks Conclusion Challenges
    1 SNMP query probe Passive Medical device supports LLDP to be able to be queried through switch Not required if Device Sensor enabled. Configure SNMP at NAD settings in ISE / CPPM, and it will probe periodically, or it can be triggered upon RADIUS accounting start / SNMP trap This probe mainly able to profile devices based on CDP or LLDP, especially IP camera, IP phones, infrastructure devices (such as AP).  This might not be feasible if CDP / LLDP is turned off

    Hi,

    SNMP trap was mandatory in earlier versions of ClearPass to profiler devices through NAD >> SNMP Read. But now it is just an option starting with 6.8.1.
    You are good with periodic polling without traps.
