Can NetFlow Analyzer report on layer2-switched flows?

Hi,
I've a Cisco 6500 that supports netflow of layer2 traffic. I've followed Cisco's steps for enabling this, but I only see flows associated with layer3 interfaces in the analyzer.

Is what I'm trying to do even possible with this tool?

Thanks,
Andy
