By default, the
operator of a class is
AND.
3. Configure a match criterion to match
the specified inner VLAN IDs.

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

12. Enter Ethernet interface view or port
group view of the service provider
network-side port.

Configuring the TPID value in VLAN tags
Tag Protocol Identifier (TPID) identifies a frame as an 802.1Q tagged frame. According to 802.1Q, the
TPID of tagged frames is 0x8100. This value varies with vendors. On the device, the TPID in the 802.1Q
tag added on a basic QinQ-enabled port is always 0x8100. In a multi-vendor network, you must set the
TPID setting on one vendor's device to be compatible with another vendor's device.
TPID settings include CVLAN TPID and SVLAN TPID.
A basic QinQ or customer-side QinQ enabled port uses the CLAN TPID to match incoming tagged
frames. An incoming frame is handled as an untagged frame if its TPID is different from the CVLAN TPID.
The device supports one CVLAN TPID for all QinQ-enabled ports. For more information about
customer-side QinQ, see " Configuring VLAN mapping ."
A service provider-side port uses the SVLAN TPID to re-mark the TPID in outgoing frames' SVLAN tags, in
addition to matching incoming tagged frames. SVLAN TPIDs are configurable on a per-port basis.
For example, the PE device is connected to a customer device that uses the TPID 0x8200 and to a
provider device that uses the TPID 0x9100. To be compatible with these devices, you must configure
