5. Configure the QinQ tunnel port to join the SPVLAN as an untagged
member (switchport allowed vlan, page 32-14).
6. Configure the SPVLAN ID as the native VID on the QinQ tunnel
port (switchport native vlan, page 32-13).
7. Configure the QinQ uplink port to join the SPVLAN as a tagged
member (switchport allowed vlan, page 32-14).
Limitations for QinQ
1.
The native VLAN for the uplink ports and tunnel ports cannot be the
same. However, the same service VLANs can be set on both uplink
and tunnel ports.
2. IGMP Snooping should not be enabled on an access port.
3. If the spanning tree protocol is enabled, be aware that an access or
tunnel port may be disabled if the spanning tree structure is
automatically reconfigured to overcome a break in the tree. It is
therefore advisable to disable spanning tree on these ports.
