How to Configure Netflow and Templates on Cisco 12410 IOS 12.0

Hello all, i need to know how to configure netflow on cisco 12410 router in order to get valid FLOWS on a Harvester i installed, i found a documente where mention how to configure but i receive an unknow template from routers, i think that i need to configre something else but dont know what, this is the router configuration i set:

ip flow-cache timeout active 1

ip flow-sampling-mode packet-interval 1000

ip flow-export source Loopback0

ip flow-export version 9

ip flow-export template options export-stats

ip flow-export template options sampling

ip flow-export template options timeout-rate 5

ip flow-export template timeout-rate 5

ip flow-export destination x.x.x.x 9995

and this is the out from parser:

Unknown V9 Flow Set IDs detected - couldn't read 2859 flows (17.4 percent) due to missing netflow template(s).

Unknown flow set id: 256 - 3390 flows (20.6 percent).

Unknown flow set id: 258 - 899 flows (5.5 percent).

Known flow set id: 256 - 13610 flows (82.6 percent).

The error states that Router is not sending the correct netflow template with netflow export. We had a simmilar problem which went away with a reboot but our problem was related to moving from Netflow Version 5 to 9 being configured on the router.

You can try a reload and see if that fixes your problem, if not try to configure netflow version 5 and see if harvesters see the flows correctly

if

that does not work, confiugre V9 back and open a Tac case
