I have a cisco 2821 router that I need to configure netflow on.  I just got Solarwinds Orion with the Netflow addin, but I need to cofigure my router for netflow first.  My collection port number in solarwinds is 2055.  I want to configure netflow on the below interface:

interface GigabitEthernet0/0
 description Verizon_T1
 ip address x.x.x..97
 ip nat inside
 ip policy route-map CABLE-WEB
 duplex auto
 speed auto

What do I have to do to configure netflow on this interface?  Thanks.

you need:

Router(config-if)# ip route-cache flow
Router(config)# ip flow-export source Giga 0/1
Router(config)# ip flow-export version 5 origin-as
Router(config)# ip flow-export destination xx.xx.xxx.xxx 2055
Router(config)# ip flow-cache timeout active 5
Router(config)# ip route-cache flow
