1.2(0.899)

Description (partial)

Symptom:
While using profiling with SNMP v3 Query and Trap probes, the correct profiling information is not fetched. The SNMP v3 queries triggered by the SNMP traps generated by linkup/linkdown or mac-notification from the switch fails SNMP v3 authorization and leads to closing of the SNMP session. 
The same is seen when the SNMP v3 query is triggered by a Radius Accounting probe.

In the profiler.log, we can clearly see that the SNMP v3 authorization fails and the SNMP session is closed.

Conditions:
This error is seen when using ISE 1.2 with SNMP v3 query probes for profiling. SNMP v2c query probes, however, work perfectly fine.
