This VLAN VPN function is implemented on the VPN Config, VLAN Mapping and Port Enable 
pages. 

This page allows you to enable the VPN function, adjust the global TPID for VLAN-VPN packets 
and enable the VPN up-link port. When VPN mode is enabled, the switch will add a tag to the 
received tagged packet basing on the VLAN mapping entries. 

Choose the menu VLAN→VLAN VPN→VPN Config to load the following page. 

 

Figure 6-12 VPN Global Config 

The following entries are displayed on this screen:

 



Allows you to Enable/Disable the VLAN-VPN function. 

Enter the global TPID (Tag protocol identifier).   



Select the desired port as the VPN Up-link port. It’s required to set the port connected to the 
operators’ backbone networks to be up-link port.   

If VPN mode is enabled, please create VLAN Mapping entries on the VLAN Mapping function 
page. 

VLAN Mapping function allows the VLAN TAG of the packets to be replaced with the new VLAN 
TAG according to the VLAN Mapping entries. And these packets can be forwarded in the new 
VLAN. If VLAN VPN function is enabled, a received packet already carrying a VLAN tag will be 
tagged basing on the VLAN Mapping entries and becomes a double-tagged packet to be 
forwarded in the new VLAN.
