3.
Configure the trusted
packet priority type.
•
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
Use one of these commands.
By default, an Ethernet 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
Remarks
1.
Enter system view. system-view N/A

interface.
qos priority priority-value
The default setting is 0.
Displaying and maintaining priority mapping
Execute display commands in any view.
Task Command

Network requirements
As shown in
, the packets from Device A and Device B to Device C are not VLAN tagged.
Configure Device C to preferentially process packets from Device A to Server when Ten-GigabitEthernet
1/0/3 of Device C is congested.
