dot1q tunneling ethertype
To configure the Ethertype, used by peer devices when implementing QinQ VLAN tagging, to be 0x9100, use the dot1q tunneling ethertype command in the interface configuration mode for an Ethernet interface. To return to the default Ethertype configuration (0x8100), use the no form of this command.
dot1q tunneling ethertype {0x9100 | 0x9200}

Usage Guidelines
The dot1q tunneling ethertype command can be applied to a main interface. When applied to the main interface, it changes the subinterfaces, that have been configured with an encapsulation dot1q second-dot1q command, under that main interface.
This command changes the outer VLAN tag from 802.1q Ethertype 0x8100 to 0x9100 or 0x9200.
