4.7 Frame Tagging

In this tutorial, shows you how to configure ports 1 and 2 on the switch to tag incoming frames with the service provider’s VID of 37 (ports are connected to customer A network) and how to set the priority for ports 1 and 2 to 3.

The scenario is that both A and B are Service Provider’s Network (SPN) customers with VPN tunnels between their head offices and branch offices respectively. Both have an identical VLAN tag for their VLAN group. The service provider can separate these two VLANs within its network by adding tag 37 to distinguish customer A and tag 48 to distinguish customer B at edge device x and then stripping those tags at edge device y as the data frames leave the network.
