7. Configure the QinQ tunnel uplink port to dot1Q-tunnel uplink mode
(
switchport dot1q-tunnel mode ).
8. Configure the QinQ tunnel uplink port to join the SPVLAN as a tagged
member (
switchport allowed vlan ).
Limitations for QinQ
◆ The native VLAN for the tunnel uplink ports and tunnel access ports
cannot be the same. However, the same service VLANs can be set on
both tunnel port types.
◆ IGMP Snooping should not be enabled on a tunnel access port.
◆ If the spanning tree protocol is enabled, be aware that a tunnel access
or tunnel uplink 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.
