Hi everyBody,
I try to tag mark packets 802.1p (with XP) with QOS_TRAFFIC_CLASS, may I have to modify my NDIS parameters
Thanks you...

In XP, you use the traffic control (TC) API to set 802.1p tag. You don't have to do anything with NDIS. The following thread on this forum seems to be asking the same question: http://forums.microsoft.com/MSDN/ShowPost.aspx PostID=1583271&SiteID=1

You can use GQoS to set 802.1p, but you have to change a registry value to enable this, and GQoS does not allow you to specify an arbitrary 802.1p value. You can only specify a traffic class, which uses the conformant 802.1p value defined by PSched Group Policy settings.

Hi gabe
In fact, I try to set 802.1p bit on outgoing packets for a specifics ports only
So I think I can't use GQOS with the registry but I should use TC API .
I try to use it like youss_75019 but it didn't work .
However the DSCP work fine.
I don't understand why .
Thank 's

When you say it doesn't work, what does that mean How are you validating that the 802.1p tag isn't getting set on the outgoing frames Do you have 802.1p tagging enabled on the Ethernet driver (it is disabled by default) Also note that taking a network capture using NetMon or Ethereal (etc.) will not show you the tag because those filter drivers operate above the miniport (the tag won't be added yet). Also note that if you were to run a sniffer on a receiving machine, it is documented NDIS behavior to strip the tag in the miniport before sending it up the stack toward TCP/IP.
