Configuring the TPID for VLAN-tagged packets
To configure VLAN termination on a Layer 3 Ethernet subinterface, Layer 3 aggregate subinterface, Layer
3 VE subinterface, or VE-L3VPN-Access subinterface, set the TPID value in the outermost VLAN tag of
packets received and sent by the main interface. When the interface receives a packet, it checks the TPID
value in the outermost VLAN tag of the packet. If the TPID value is 0x8100 or the configured value, the
interface considers the packet as a VLAN-tagged packet. 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.
To set the TPID value for VLAN-tagged packets:
