thansk for quick reply sandeep ,

On my 6509 it doesnt give option to configure netflow . Output is below . IOS is 15.1(1)SY1

6509(config)#ip flow?

% Unrecognized command

[Sandeep Choudhary]

use ip flow-export ?

use layer 3 interface to configure ip flow command not layer 2

6509(config)#ip flow-export ?

6509(config)#flow ?

  exporter  Define a Flow Exporter

  hardware  Hardware config commands

  monitor   Define a Flow Monitor

  platform  Platform flow commands

  record    Define a Flow Record

Amit,

I think traditional NetFlow is not supported in 15.1SY, you have to use Flexible NetFlow:

Flexible Netflow Configuration Guide, Cisco IOS Release 15SY

Unfortunately I don't have any experience with Flexible NetFlow yet but this Cisco Live Session sounds interesting:

"... The new Flexible NetFlow feature is covered in detail. ..."

I think traditional NetFlow is not supported in 15.1SY, you have to use Flexible NetFlow:

After comparing the data-sheets I think it actually depends on the supervisor-engine.

I guess you have a 2T?

hello Thanks for reply ,

Yes my SUP is VS-SUP2T-10G , so if my understanding is right I cant use Netflow with SUP 2T ?

[Sandeep Choudhary]

HI Amit,

SUP 2T supports Netflow with IOS is 15.1(1)SY1
