Packets are always transmitted by the system using the primary TPID value in the outer VLAN tag. It is not possible to configure an inner VLAN TPID value. The inner VLAN TPID value is always 802.1Q (0x8100). Use the switchport dot1q ethertype Interface Configuration mode command to apply a configured TPID value to an interface. Example This example defines the VMAN (0x88A8) TPID for use on a service provider (SP) port and configures a service provider port (Te1/0/1) in general mode after creating the common SP/CE VLAN. The port is configured in general mode and to only allow tagged packets on ingress using the outer VLAN ID 10. Then, the port is configured to accept the VMAN TPID in the outer VLAN on ingress and further configured to tag packets with the VMAN TPID and VLAN ID 10 in the outer VLAN tag on egress. This example configures an SP port using general mode. console(config)#switchport dot1q ethertype vman console(config)#vlan 10 console(config-vlan10)#exit console(config)#interface te1/0/1 console(config-if-Te1/0/1)#switchport mode general console(config-if-Te1/0/1)#switchport general allowed vlan add 10 tagged console(config-if-Te1/0/1)#switchport dot1q ethertype vman primary-tpid This example configures an SP port using trunk mode. console(config)#switchport dot1q ethertype vman console(config)#vlan 10 console(config-vlan10)#exit console(config)#interface te1/0/1 console(config-if-Te1/0/1)#switchport mode trunk console(config-if-Te1/0/1)#switchport trunk allowed vlan 10 console(config-if-Te1/0/1)#switchport trunk native vlan 10 console(config-if-Te1/0/1)#switchport dot1q ethertype vman primary-tpid Layer 2 Switching Commands 905
