Configuring the trusted packet priority type for an interface or port group

When you configure the trusted packet priority type on an interface or port group, use the following available keywords:

dot1p—Uses the 802.1p priority of received packets for mapping.
dscp—Uses the DSCP precedence of received IP packets for mapping.

The following matrix shows the dscp keyword and hardware compatibility:

Hardware	Keyword compatibility
MSR900	No
MSR93X	Yes
MSR20-1X	No
MSR20	No
MSR30	Supported only on MSR30-11E and MSR30-11F
MSR50	No
MSR1000	Yes

To configure the trusted packet priority type on an interface or port group:

Step	Command	Remarks
1. Enter system view.	system-view	N/A
2. Enter interface view or port group view.	Enter interface view:interface interface-type interface-number Enter port group view:port-group manual port-group-name	Use one of the commands. Settings in interface view (Ethernet or WLAN-ESS) take effect on the current interface. Settings in port group view take effect on all ports in the port group.
3. Configure the trusted packet priority type for the interface or port group.	qos trust { dot1p \| dscp }	N/A
