CONFIGURING THE SWITCH
Note: QinQ “customer” ports are those ports that are connected to normal VLAN aware switches in the customer’s network. QinQ “network” ports are those which are connected to the service provider's network. To tunnel packets through a service provider’s metro network, QinQ needs to be enabled on the network port.
•Packet Type – Sets the interface to accept all frame types, including tagged or untagged frames, or only tagged frames. When set to receive all frame types, any received frames that are untagged are assigned to the default VLAN. PCs should be connected to ports with Packet Type set to “All.” PCs cannot, in general, send or receive tagged packets. Switches should be connected to each other with Packet Type set to “Tagged.” If the Packet Type is set to “All,” the port can accept incoming tagged and untagged packets. Untagged packets will be associated with the VLAN identified by the PVID. Tagged packets will be dropped unless the port is a member of the VLAN identified by the VLAN tag in the packet. Outgoing packets will be tagged unless the packet’s VLAN ID is the same as the PVID. If the Packet Type is set to “Tagged,” the port will drop untagged packets and will only send and receive tagged packets. Tagged packets will be dropped unless the port is a member of the VLAN identified by the VLAN tag in the packet. The PVID has no effect in this case.(Option: All, Tagged; Default: All)
•PVID – VLAN ID assigned to untagged frames received on the interface. The PVID (Port VLAN ID) is the VLAN ID that is associated with untagged, ingress packets. It is not possible to remove a port from VLAN 1 unless its PVID has been changed to something other than 1. The PVID has no effect on ports that have Packet Type set to Tagged. (Default: 1)
