Example
In the user view, run the display current-configuration interface command, and you can check
the configuration of VLAN mapping of double tags on an interface.

4.5 Configuring Flow-based VLAN Mapping

This section describes how to configure flow-based VLAN mapping.

4.5.1 Establishing the Configuration Task

4.5.2 Replacing a Single Tag
4.5.3 Replacing Double Tags
4.5.4 Replacing the Outer VLAN Tag
4.5.5 Checking the Configuration
4.5.1 Establishing the Configuration Task
Applicable Environment
When two private networks in different VLANs communicate with each other through a public
network, the user packets may carry one or two VLAN tags when arriving on the ISP network.
You can configure VLAN mapping of a single VLAN tag or double VLAN tags on the edge
device of the public network so that the VLANs of private networks and public network can be
separated. This saves VLAN resources of the public network.
