Note
Do not set TPID to be 0x0806(ARP), 0x0200(PUP),
0x8035(RARP), 0x0800(IP), 0x86DD(IPv6),
0x8863/0x8864(PPPoE), 0x8847/0x8848(MPLS),
0x8137(IPX/SPX), 0x8000(IS-IS), 0x8809(LACP),
0x888E(802.1x), 0x88A7(cluster), and 0x0789(reserved).
12.2.5.3 Configuring Priority
Duplication
Follow these steps to duplicate the priority of inner tag to outer tag:
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) to the priority value of the outer tag (ISP
tag).
End
Exit the interface mode.
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.
For DES-7200 series, priority duplication takes effect only
after this trust mode is enabled.
The following example shows how to configure the priority duplication of the
user tag:
DES-7200(config)# interface gigabitethernet 0/1
DES-7200(config-if)# mls qos trust cos
DES-7200(config-if)# inner-priority-trust enable
DES-7200(config)# end
DES-7200# show inner-priority-trust interface gigabitethernet 0/1
Port inner-priority-trust
