Which ISO to support ip route-cache ???

gginty · ‎03-24-2009

I need to enable netflow on our 3750/3650 switches. The command structure is "ip route-cache flow". However when I try to ad this, I get the usuall unrecognised command. I have taken a look on Cisco, but cannot find the right ISO version to enable this command.

our current version is 12.2(25) for the 3750's and 12.2(35) for the 3650's

Thanks

NetFlow isn't supported on 3750/3560 switches regardless the IOS version. It's hardware limitation.

For NetFlow support on switches, you need the 4500 (with some caveats) or 6500 Series.

HTH,
