    VLAN termination configuration commands dot1q ethernet-type Use dot1q ethernet-type to set the TPID value in the outermost VLAN tag of packets received and sent by the interface. Use undo dot1q ethernet-type to restore the default. Syntax dot1q ethernet-type hex-value undo dot1q ethernet-type Default The TPID value for the outmost VLAN tag of VLAN-tagged packets received and sent by the interface is 0x8100.

    Usage guidelines After you execute the dot1q ethernet-type command, only packets whose TPID in the outermost VLAN tag is 0x8100 or the value you configured will be processed as VLAN-tagged packets. When sending a packet, the interface sets the TPID value in the outermost VLAN tag to the configured value, and sets the TPID values in the other VLAN tags to 0x8100 if the packet carries two or more layers of VLAN tags.
