Set the TPID value inthe outer VLAN tag ofpackets received andsent by the interface.qinq ethernet-type [ service-tag ]hex-valueOptional.By default, the TPID value in theouter VLAN tag is 0x8100.If the interface receives and sendsQinQ packets, the TPID value inthe inner VLAN tag of packets isalways 0x8100, and is notconfigurable.NOTE:For more information about the qinq ethernet-type command, seeLayer 2—LAN Switching CommandReference.Enabling a QinQ termination-enabledinterface/subinterface to transmit broadcast andmulticast packetsBy default, an ambiguous QinQ termination-enabled subinterface or VLAN interface drops broadcastand multicast packets it receives, instead of transmitting them.You can enable an ambiguous QinQ termination-enabled Layer 3 Ethernet/aggregate subinterface orVLAN interface to transmit broadcast and multicast packets.To enable an ambiguous QinQ termination-enabled Layer 3 Ethernet/aggregate subinterface or VLANinterface to transmit broadcast and multicast packets:Step Command Remarks1.
