Step 3. Configure the trusted packet priority type. Command • Configure the interface to trust the DSCP precedence. qos trust dscp • Configure the interface to trust the 802.1p priority of received packets. qos trust dot1p • Configure the interface not to trust any packet priority. undo qos trust Remarks Use one of these commands. By default, an interface does not trust any packet priority. Changing the port priority of an interface If an interface does not trust any packet priority, the device uses its port priority to look for the set of priority parameters for the incoming packets. By changing port priority, you can prioritize traffic received on different interfaces. To change the port priority of an interface: Step Command 1. Enter system view. system-view 2. Enter interface view. interface interface-type interface-number 3. Set the port priority of the interface. qos priority priority-value Remarks N/A N/A The default setting is 0 for devices supporting only one port priority type. Displaying and maintaining priority mapping Execute display commands in any view. Task Display priority map configuration. Display the trusted packet priority type on a port.
