Netflow not working on some router models

Hi,

I am having problems running netflow on my cisco837 adsl routers (running IOS 12.3(8)T11). I am using exactly the same configs on my Cisco2600's and they work well but for some reason even though the 837's accept all the commands they are not exporting any data.

The config lines are:

ip flow-cache timeout active 1

ip flow-export version 5

ip flow-export destination x.x.x.x 2055

and under each interface:

ip route-cache flow.

On my 2600's this config works and I see results within "sh ip flow export" and on my viewing application. For the 837's all the exports within "sh ip flow export" read 0 and no data is being sent.

Any ideas why this is the case ?

Re: Netflow not working on some router models

Is CEF enabled?

ip cef

Also Cisco's Feature Navigator doesn't list Netflow as an available feature on your platform/IOS combo.
