Netflow- IOS vs ASA

Imran Ahmad — Tue, 12 Mar 2019 05:05:13 GMT

Hello,

What is difference in-between netflow on IOS and ASA ?

Also I want to know does the Next-Generation ASA, and ASA with FirePower support pure Netflow features as IOS ?

or they still use old NSEL feature?

Thanks,

It still uses the NSEL, Im not sure about sourceFire yet.

The firewall uses version 9 which would send more information about the flow creation/deletion and can give any advantage that Version 9 can offer.
