4.5.5 Q-IN-Q
Q-in-Q is commonly referred as VLAN stacking in which VLANs are nested by adding two tags to
each frame instead of one. Network service provider and users both can use VLANs and makes
it possible to have more than the 4094 separate VLANs allowed by 802.1Q.
There are three ways in which a machine can be connected to a network carrying double-
tagged 802.1ad traffic:
via a untagged port, where both inner and outer VLANs are handled by the switch or
switches (so the attached machine sees ordinary Ethernet frames);
via a single-tagged (tunnel) port, where the outer VLAN only is handled by the switch (so
the attached machine sees single-tagged 802.1Q VLAN frames); or
