Hi,
Can anyone confirm this for me? My ix1 is duplicating frames (10 gig copper).
I switched the ports on the switch as well, it carried over.
I did a ping from a mac mini from behind this router and it did not carry over
a duplicate, so I'm wondering whether it's just a bpf bug?

I've had this before and it was a bad cable but I think the duplicates carried
over then..here they aren't being routed/carried over.

That's the interface in question.
