Configuring Priority Duplication

Command
Description
configure terminal
Enter the global configuration mode.
interface <interface>
Enter the interface configuration mode.
mls qos trust cos
Configure the interface to be trust CoS mode.
inner-priority-trust enable
Copy the priority value of the inner tag (user

tag).
End

show inner-priority-trust
View the priority duplication configuration of
the user tag.
Note
 You can configure priority duplication of the user tag only on
the dot1q-tunnel port, whose priority is higher than QoS in
the trusted mode but lower than flow-based QOS.
 Priority duplication and priority mapping cannot be enabled
on one interface at the same time.
The following example shows how to configure the priority duplication of the
user tag:
Ruijie(config)# interface gigabitethernet 0/1
Ruijie(config-if)# mls qos trust cos
Ruijie(config-if)# inner-priority-trust enable
Ruijie(config)# end
Ruijie# show inner-priority-trust interface gigabitethernet 0/1
