Cisco 4500 series and netflow

Normally on a Cisco router, you can export by using ip route-cache flow commands on each interface you want to monitor and ip flow-export to your collector. No problem… On a Cisco 4500 series L3 switch netflow doesnt work on each interface so you enable the command globally. It still won’t work unless you have met the following conditions:

Supervisor IV or a Supervisor Engine V

NetFlow Services daughter card(WS-F4531)

IOS version 12.1(19)EW or above to support NDE

Here are the commands:

switch>(enable)ip flow-export destination 9996
switch>(enable)ip flow-export version 7
switch>(enable)ip flow-export source FastEthernet 0/1
switch>(enable)ip flow-cache timeout active 1
switch>(enable)ip route-cache flow infer-fields
