Why each option
Cisco ISE listens on UDP port 9996 by default to receive NetFlow version 9 probe data from network access devices for endpoint profiling.
UDP 9996 is the default port configured on Cisco ISE to receive NetFlow v9 traffic from routers and switches. The ISE profiling service binds to this port to collect flow records and build endpoint profiles based on observed network behavior.
UDP 9997 is not the default NetFlow v9 probe port in Cisco ISE; it is not assigned to NetFlow collection in the ISE profiling configuration.
UDP 9998 is not associated with NetFlow v9 probe collection in Cisco ISE; this port is not used by the profiling service for NetFlow.
UDP 9999 is not the default NetFlow v9 probe port in Cisco ISE; the correct default is 9996.
Concept tested: Cisco ISE NetFlow v9 probe default UDP port
