I have a application that is providing a COS 5 tag yet it is not connected via a trunk (and the NIC dosen't support 802.1P). I ran ethereal capture on this PC and see DSCP class selector 5 under IP layer for the source packets going out. How is ethereal seeing a class selcter of 5 (layer 3) when I believe I'm tagging at layer 2? Shouldn't I see this 802.1P header in my capture even though it is probably stipped off by the switch (since I'm not turnking)? I'm trying to verify the 802.1P tag going out and see class selector 5 so it looks like something is working but where's my actual 802.1P tag then?
