I capture traffic with Microsoft Network Monitor 3.4 and get a strange behavior with an Intel Dual Band Wireless-AC 8260 card (WMM certified, driver 184.108.40.206), connected to a Cisco Access point (2702I) with QoS enable.
IP packet are well tagged on both direction (up and downstream) as DSCP 46 for voice traffic by the application, but:
- in downstream, Qos Control Priority (UP) is set to 6 (AC_VO voice) by the access point: this is a correct comportement
- in upstream, no mark of any : this is the purpose of my question
Does the wireless card able to set the WMM UP field? Is anybody have more information about this?
Thank you for joining the Intel Communities.
Let me do further research about this and come back to you. I will post information on this thread as soon as I have it.
Hello, i Got the same issue and tryied capturing packets over the air using network monitor 3.4 and an open ssid, traffic is well marked with qos UP for upstream evenbt that capturing within sender pc dont shows it,
dscp46 => 5 UP as Microsft uses 3 MSP of the dscp to generate UP tag https://clnv.s3.amazonaws.com/2018/usa/pdf/BRKRST-2515.pdf https://clnv.s3.amazonaws.com/2018/usa/pdf/BRKRST-2515.pdf
