Some Nodes not checking into Netflow

Hi,

We've got a network of around 100 Cisco routers checking into Netflow.

I've got several routers which have Dialer Interfaces with a bound Virtual Access interface where only one of the two interfaces will send netflow information to Orion.

I've tried re-adding the node and the configuration on the devices is identical. What is particuarly odd is the Virtual Access interfaces are clones of the Dialers so I don't understand why they won't talk to Orion.

SNMP traffic is working fine its purely Netflow

Could anyone shed some light on a possible cause?

Do all the interfaces have valid and unique interface indexes? You can verify this using a packet capture on the Orion server or MIB walk on the router.
