Configuring the SVLAN TPID
When you configure the SVLAN ID, follow these restrictions and guidelines:
•
Configure the SVLAN TPID on service provider-side ports of PEs.
•
Do not configure the SVLAN TPID on a QinQ-enabled port.

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:
•
Sets an 802.1p priority value in the SVLAN tag depending on the VLAN ID or 802.1p priority in
the CVLAN tag.
•
Copies the 802.1p priority in the CVLAN tag to the SVLAN tag.
