4.4.7.5 VLAN Translation Configuration
Besides the aforementioned ways of creating VLANs, another way to establish the translated
VLANs is to configure VLAN ID translation (or VLAN mapping) on trunk ports connected to a
customer network to map the original VLANs to the translated VLANs. Through this VLAN ID
translation, it will save much effort in massive Ethernet network deployments.
Packets entering the trunk port are mapped to a translated VLAN based on the port number and
the original VLAN ID of the packet. In a typical metro deployment, VLAN mapping takes place on
user network interfaces. Because the VLAN ID is mapped to the translated VLAN on ingress, all
forwarding operations on the Managed Switch are performed with the usage of the translated
VLAN information rather than the original VLAN information.
VLAN Translation: Enable or disable VLAN Translation function globally. Click OK provided for
VLAN Translation function, the new settings will be taken effect immediately.
Click New to add a new VLAN mapping rule and then the following screen page appears.
Click Edit to modify the configuration of the selected VLAN mapping rule by clicking on the
checkbox of the corresponding rule.
Click Delete to remove an existing VLAN mapping rule by clicking on the checkbox of the
corresponding the rule. To remove all rules you had created from the VLAN mapping rule table,
you can click on the top checkbox of this table to choose all of these rules at a time, and then click
Delete.
