Figure 16: Port-Based Q-in-Q
This example shows how to configure switch A with port 1 on the switch to tag
incoming frames with the service provider’s VID of 200 (ports are connected to
customer X network) and configure port 7 to the service provider’s VID of 100
(ports are connected to customer Y network). This example also shows how to set
the priority for port 1 to 3 and port 7 to 4.
7.2.3.3.2 Selective Q-in-Q
The traffic-based Q-in-Q is also called selective Q-in-Q. Selective Q-in-Q allows
the switch to add different outer VLAN tags to the incoming frames received on
one port according to their inner VLAN tags. In Selective Q-in-Q mode, the
switch performs traffic classifies the incoming traffic on a port based on the
VLAN ID. When a user uses different VLAN IDs for different services, traffic
can be classified according to the VLAN ID. Example: VLAN ID 100 for surfing
on the Internet on a PC, VLAN ID 200 for IPTV and VLAN ID 300 for VIP
customers. After receiving user data, the switch labels the traffic for surfing on the
Internet on a PC with 500 as a SPVID outer tag, IPTV with 600 and VIP
customers with 700.
This following example shows how to configure port 3 on the switch to tag
incoming frames with the different service provider’s VID and priority.
