What are the 2 egress traffic types collected by NetFlow?
2. MPLS to IP packets.
What does the new Flexible NetFlow add to the NetFlow possibilities?
1. Flow Records (Key and non-key fields)
2. Flow Monitors (Applied to an interface to perform network traffic monitoring)
3. Flow Exporters (Exports NetFlow Version 9 data from the Monitor cache to a remote host or NetFlow collector)
4. Flow Samplers (Samples partial NetFlow data rather than all data)
What are up and downside of using sampled NetFlow data?
A downside however is that important data can be missed because only sampled data is gathered.
