switchport dot1q ethertype (Global Configuration) Use the switchport dot1q ethertype command to define additional QinQ tunneling TPIDs for matching in the outer VLAN tag of received frames. Use the no form of the command to remove the configured TPIDs. Syntax switchport dot1q ethertype {vman | custom 1-65535} no switchport dot1q ethertype {vman | custom 1-65535} • vman-Define the Ethertype as 0x88A8. • custom-Define the Ethertype as a 16 bit user defined value (in decimal). Default Configuration 802.1Q is the default Ethertype for both inner and outer VLAN TPIDs. The 802.1Q TPID cannot be removed from the configuration. By default QinQ processing of frames is disabled. Command Mode Global Configuration User Guidelines This command globally defines additional TPIDs for use by the system for matching of ingress packets in the outer tag. The switch uses the default primary TPID 0x8100 and any of the additional TPIDs to match packets in the outer tag on ingress. A TPID must be configured globally before it can be applied to an interface. Up to three additional TPIDs can be configured for acceptance in the outer VLAN tag on the SP port. Packets received on the SP port which do not contain one of the configured TPIDs or which do not contain the SP VLAN ID in the outermost VLAN tag are processed by the port as if they are not part of the QinQ tunnel. Use the no form of the command to remove an additional TPID. Doing so removes the TPID from all interfaces. If the removed TPID is the primary TPID for an interface, the interface is configured to use the default primary TPID 0x8100. Layer 2 Switching Commands 904
