Bad advice. No amount of money will fix major platforms that are not 
happy to export flow telemetry via router management ports. Sometimes it 
can be done via nasty vrf leaking hacks, sometimes it cannot be done at 
all. Management ports are typically directly connected to routing 
engines while netflow data is generated in hardware in PFE.

In-band netflow works on all platforms without such issues.
