BVI interfaces not showing netflow data on NTA 4.1.0

Question

We are receiving netflow data from many interfaces successfully on Cisco ASR9000 routers, but we are not able to display data from any BVI interfaces.

The BVI interfaces are showing up in Netflow Sources, and are being reported as delivering netflow data, but I cannot get any BVI interface to display anything other than what is shown above.

I have no idea whether this is a display issue, a reporting issue in the sources view, or what exactly is happening here.

Is anyone able to display netflow data from Cisco BVI interfaces, monitored as BVI only (not monitoring the physical interfaces that host them)?

A quick look tells me that Netflow is only supported on "Enhanced Ethernet Line Cards" for BVI's, not A9K-SIP-700 line cards or ASR 9000 Ethernet Line Cards. Not knowing your config it could be this. More details would help, both in terms of the hardware you're working on and the Netflow configuration you're using?

Here is the docs I'm looking at: http://www.cisco.com/c/en/us/td/docs/routers/asr9000/software/asr9k_r4-2/netflow/configuration/guide/b_netflow_cg42asr/b_netflow_cg42asr_chapter_00.html#concept_2B1F0E82974C4792802749EA8569B3BD
