2.2(0.470) 2.3(0.298)

Description (partial)

Symptom:
ISE MnT Live sessions (and subsequently) Pxgrid Susbscribers like FMC, SMC etc would not have accurate User/IP mappings. The live-sessions record for the user would have a different IP address, normally the one belonging to previous session/user/machine.

Conditions:
Seen in scenarios where DVLANs are pushed via ISE Authz profiles and user changes VLAN after authentication. This creates a scenario where multiple accounting packets are sent for the same endpoint from the NAS withing 5 seconds. Seen when ISE Client suppression feature is enabled. (Enabled by default)
