When I create a QoS policy in Windows 7 through the Group Policy editor and set a DSCP value, does Windows 7 add the 802.1p QoS field to the Ethernet frame? If so, how does it map the different values from DSCP (0-63) to the 802.1p QoS values (0-7)?
So to be clear, my questions are:
- Does Windows 7 set an 802.1p value for configured QoS policies?
- If so, how does Windows 7 map the QoS-policy's DSCP value to the 802.1p value?
This question is specifically for outgoing packets.
Note: 802.1p tagging is supported in Windows 7 (and has been since Windows 2000, XP SP2, Windows Server 2003). Microsoft seems to allude to a mapping of DSCP to 802.1p in this document.
