1.14 Configuring Traffic-Based Selective QinQ

QinQ is to encapsulate the VLAN tags of the private network in the VLAN tags of the
public network in order that the frames are transmitted through the backbone network
of the service provider network (also called public network). The traffic-based selective
QinQ feature can tag a frame with an outer VLAN tag according to the ACL rule that the
frame matches on the inbound port.
The traffic-based selective QinQ feature is usually configured on the hybrid port of the
edge device connecting the user device to the service provider network.

1.14.1 Configuration Prerequisites

ACL rules used for traffic identifying are defined. Refer to the ACL module in this
manual for defining ACL rules.
ID of the outer VLAN tag is specified.
The ports that needs this configuration are specified
