Tracing packets on layer2?

[fearless.rabbit]

Hey everyone,

I got a quick question for you. A while ago, when I watched some switching video tutorials, I think I heard there is a Layer2 equivalent to Layer3 trace routing. Like you trace hops packet goes through with traceroute, there is supposed be some mechanism than enables you to track packets on Layer2.

I could use this big time. Seeing which paths do packets take in certain vlans would be very welcome

Thanks,

Milos

Do you know if there is any update on this making its way into NX-OS?
