Setting the 802.1p priority in SVLAN tags
By default, the 802.1p priority in the SVLAN tag added by a QinQ-enabled port depends on the priority
trust mode on the port.
• If the 802.1p priority in frames is trusted, the device copies the 802.1p priority in the CVLAN tag to
the SVLAN tag.
• If port priority is trusted, the port priority (0 by default) is used as the 802.1p priority in the SVLAN
tag.
To set the 802.1p priority in SVLAN tags:
