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.
This command sets the switch to operate in QinQ mode. Use the no form
to disable QinQ operating mode.
