Who has the experience on the Netflow?

Unanswered Question
Apr 10th, 2010

Hi Everyone,

Recently I want to implement Netflow in my network,but I encountered trouble.

The issue is the Netflow can't accurately capture flow.

I think the problem is caused by Policy-Based Routing.

If you are interested in this issue, please reply this discuss, I hope you solve this problem together.

Thank you very much!

I have this problem too.

Hello Yuan,

in the past I've tested Netflow on several platforms including GSR Engine 0, Engine 2, Engine 3 linecards.

If I've understood correctly you suspect that PBR is making netflow  accounting not  effective.

What linecards are involved and how are configured the interfaces on it?

Are you using netflow sampling?

What is exactly the problem totally missing netflow data, or trafffic volumes appear to be not accurate ?

Hope to help
