According to product bulletin no 3209 for the Cisco 4400 series, theAccess Point supports 802.11e WMM.
My question goes to DSCP mapping, according to IEEE and your bulletinthe DSCP field in the IP header should be set to 46 (10110 00) formapping to a 802.11 QoS voice priority 6/7.
But my Wireshark trace revealed 4400N is mapping toward with 802.11QoS is set to Priority 5 Video.
If I google DSCP mapping toward 802.11 QoS all IEEE documention Ifound says EF /Voice should have 46 or 101xxx in the DSCP IP field butrunning through Cisco and HP docs gives 46 or 48 as value, that is thecorrect value....
Thanks for your answer, and I was aware of 802.1p and 802.1Q header, but the Ethernet frame the 4400N receives, as you can see in my previous entry, does not have a 802.1Q field only the DSCP field is set and the 4400N is mapping into QoS for the 801.11 header. So the 4400N must have some mapping included based on the DSCP field. I have experimented on changing only the DSCP field and the mapping from the 4400N changes.
