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.
•
If the 802.1p priority is trusted, the port copies the 802.1p priority in the CVLAN tag to the SVLAN
tag.
•
If port priority is trusted, the port sets the 802.1p priority in the SVLAN to be the same as the port
priority. The default port priority is 0.
Alternatively, you can configure a QoS policy to set the 802.1p priority in the SVLAN by using one of the
following methods:
