If it's using 8100, then the bit should be interpreted as CFI, whereas if it's using 88a8 it should be treated as DEI. Thus, if the type is 88a8, the DEI bit should be treated as such, and equipment that unconditionally drops DEI=1 traffic is Broken And Needs To Be Fixed. On the other hand, if an 8100 tagged handover is not clearing CFI, it's that end that is Behaving Badly and should be fixed. A box dropping CFI=1 traffic on traffic received with a tag type of 8100 is behaving "correctly". -- don
