• Cisco TAC states that by default Windows sets the DSCP to 0 unless an application is configured to mark its own traffic. in context
• Cisco's Windows DSCP tech note has administrators create a DWORD named Do not use NLA with value 1 under HKLM\SYSTEM\CurrentControlSet\Services\Tcpip\QoS and reboot before configuring Policy-based QoS. in context
• Cisco's tech note says that if applications such as Jabber or Webex set their own DSCP, the Policy-based QoS advanced setting DSCP marking override can be set to Allowed so policy values do not override application markings. in context
