Re: Catalyst - 6506E and Netflow

Hello,

which ports do you mean?

Could you set quicker timeout in the IOS:

ip flow-cache timeout active 2

ip flow-cache timeout inactive 24

Kind regards

Re: Catalyst - 6506E and Netflow

Hello,

I checked your configuration and the problem is in CatOS part.

remove the line:

set mls nde flow include destination 192.168.1.19/255.255.255.255

If it doesn't help, please, send me the following:

MSFC:

show ip flow export

show ip cache flow

Supervisor:

show mls nde

Kind regards,
