Setting the 802.1p priority in SVLAN tags

By default, a QinQ-enabled port sets the 802.1p priority in the SVLAN tag depending on the priority trust mode.

Alternatively, you can configure a QoS policy to set the 802.1p priority in the SVLAN by using one of the following methods:

To set the 802.1p priority in SVLAN tags:

Step

Command

Remarks

1. Enter system view.

system-view

N/A

2. Create a traffic class and enter traffic class view.

traffic classifier classifier-name [ operator { and | or } ]

By default, no traffic class is configured.

3. Configure CVLAN match criteria.

  • Match CVLAN IDs:if-match customer-vlan-id vlan-id-list

  • Match 802.1p priority:if-match customer-dot1p dot1p-value&<1-8>

N/A

4. Return to system view.

quit

N/A

5. Create a traffic behavior and enter traffic behavior view.

traffic behavior behavior-name

N/A

6. Configure a priority marking action for SVLAN tags.

  • Replace the priority in the SVLAN tags of matching frames with the configured priority:remark dot1p dot1p-value

  • Copy the 802.1p priority in the CVLAN tag to the SVLAN tag:remark dot1p customer-dot1p-trust

N/A

7. Return to system view.

quit

N/A

8. Create a QoS policy and enter QoS policy view.

qos policy policy-name

N/A

9. Associate the traffic class with the traffic behavior.

classifier classifier-name behavior behavior-name

N/A

10. Return to system view.

quit

N/A

11. Enter Layer 2 Ethernet interface view.

interface interface-type interface-number

N/A

12. Configure the port to trust the 802.1p priority in incoming frames.

qos trust dot1p

By default, the device does not trust the 802.1p priority carried in frames.

Skip this step if the remark dot1p customer-dot1p-trust command is configured.

13. Enable QinQ.

qinq enable

N/A

14. Apply the QoS policy to the inbound direction of the port.

qos apply policy policy-name inbound

N/A
