Configuring IEEE 802.1Q Tunneling
34-15
34
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.
