NetFlow export disabled main cache

I'm not sure why flow export is disabled for main cache, I've read several netflow documents on CCO, running 12.4(3b) on a 3825 Router.

3825#show ip flow export

Flow export v5 is disabled for main cache

Exporting using source interface GigabitEthernet0/0.46

Version 5 flow records

0 flows exported in 0 udp datagrams

0 flows failed due to lack of export packet

0 export packets were sent up to process level

0 export packets were dropped due to no fib

0 export packets were dropped due to adjacency issues

0 export packets were dropped due to fragmentation failures

Re: NetFlow export disabled main cache

the export is disabled because you haven't configured "ip flow-export destination " in global configuration mode.

This command configures the ip address and udp port of the netflow collector.

For more information on this command, refer to the following URL:
