Configuring IEEE 802.1Q Tunneling
– 484 –
6.
Configure the SPVLAN ID as the native VID on the QinQ tunnel access port
(
switchport native vlan ).
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

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.
