Configuring VLAN-VPN (Only for Certain Devices) Basic VLAN-VPN Configuration
2
Basic VLAN-VPN Configuration
To complete the basic VLAN-VPN configuration, follow these steps:
1) Configure 802.1Q VLAN.
2) Configure NNI ports and UNI ports.
3) Enable VLAN-VPN globally.
Configuration Guidelines
â– The TPID preset by the switch is 0x8100. If the devices in the ISP network do not
support this value, you should change it to ensure VLAN-VPN packets sent to the ISP
network can be recognized and forwarded by devices of other manufacturers.
â– You can go to 802.1Q VLAN section to specify the Ingress Checking feature according
to your needs. If the Ingress Checking is enabled, the port will perform this operation
first then process the packets based on the VLAN-VPN configuration. If Ingress
Checking is disabled, the port will process the packets directly based on the VLAN-VPN
configuration.
2.1 Using the GUI
