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.
