Appendix A
73
In the above table, we can set different VID (VLAN Identifier) for each port of the converter. QinQ support can
also be enabled. Double-tagging (QinQ) can be useful for Internet Service Providers, allowing them to use VLANs
internally while mixing traffic from clients that are already VLAN-tagged. The outer (representing ISP VLAN) tag
comes first, followed by the inner tag. In such cases, an alternate TPID such as hex 9100 may be used for the
outer tag; however this is being deprecated by 802.1ad, which specifies 88a8 for service-provider outer tags.
8. We are going to set port 3 (UTP3) to VID 10 and port 4 (UTP4) to VID20. The screen will then look like this.
This means that packets that ingress (come into) the UTP ports, from PC-A and PC-B will have their packets
tagged for VID10 and 20 respectively. Save settings with <S>.
