The interface view is displayed.
Step 3 Run:
port link-type trunk
The link type of the interface is set to trunk.
Step 4 Run:
port trunk allow-pass vlan vlan-id
The interface is added to the VLAN whose ID will replace the outer VLAN tag of frames.
Step 5 Run:
port vlan-mapping vlan vlan-id1 inner-vlan vlan-id2 [ to vlan-id3 ] map-vlan vlan-
id4 [ remark-8021p 8021p-value ]
The outer VLAN tag is replaced.

4.5 Configuring Flow-based VLAN Mapping

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

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 reaching the ISP network.
You can configure VLAN mapping of a single VLAN tag or double VLAN tags on the edge
Issue 01 (2011-07-15)
NOTE
Currently, only the E-series and F-series boards supports VLAN mapping of double tags.
VLAN mapping can be configured only on a trunk or hybrid interface. In addition, the interface must be
added to the VLAN specified by map-vlan. On S-series boards, the interface must be added to the VLAN
specified by map-vlan in tagged mode.
Run the display vlan vlan-id command to check whether the interface is added to the
translated local VLAN.
Run the display current-configuration command to display information about the
mapping of double VLAN tags on the interface.
Run the preceding command, and you can obtain the following information:
– The interface is added to the translated local VLAN.
– The information about the VLAN mapping is correct.
