Netflow & Flexible Netflow

Hi

I recently came to know that we need netflow services card (WS-F4531) for configuring the netflow on 4503 switch. Is the same required for Flexible NetFlow configurations.

Re: Netflow & Flexible Netflow

Hello Ibrahim,

Netflow was not supported on 4500 unless you added the WS-F4531 card that you mentionned (Suported on SUPERVISORs IV and V). 

http://www.cisco.com/en/US/docs/switches/lan/catalyst4500/hardware/configuration/notes/78-15214.html#wp59422

For the SUPERVISOR V-10GE, the classic Netflow functions are built-in (no need to add the Netflow service card)..

Then came the SUP-7(E or LE) & 4500X which are the first platforms to support Flexible Netfow (native functions - no need to add any additional service card).

=========================================================

Please find some elements about the differents advantages.

Q. What are the key advantages of Flexible NetFlow above traditional NetFlow?

A.

• Flexibility, scalability, aggregation of flow data beyond today's NetFlow.

• The ability to monitor a wider range of IP packet information from layer 2 to 7

• Enhanced network anomaly and security detection

• User configurable flow information to perform customized traffic identification and the ability to focus and monitor specific network behavior

• Convergence of multiple accounting technologies into one accounting mechanism

=========================================================

Hope that helps.

Regards.
