tag-protocol-id TPID(TPIDs Expected to Be Sent or Received)


Hierarchy Level


For Gigabit Ethernet IQ and 10-Gigabit Ethernet IQ2 and IQ2-E interfaces, aggregated Ethernet with Gigabit Ethernet IQ interfaces, and Gigabit Ethernet PICs with SFPs (except the 10-port Gigabit Ethernet PIC, and the built-in Gigabit Ethernet port on the M7i router), define the TPIDs expected to be sent or received on a particular VLAN. For each Gigabit Ethernet port, you can configure up to eight TPIDs using the tag-protocol-id statement; but only the first four TPIDs are supported on IQ2 and IQ2-E interfaces.

For 10-Gigabit Ethernet LAN/WAN PIC interfaces on T Series routers only the default TPID value (0x8100) is supported.

For Gigabit Ethernet, 10-Gigabit Ethernet, 40-Gigabit Ethernet, and aggregated Ethernet interfaces on EX Series switches, define the TPIDs expected to be sent or received on a particular VLAN. The default TPID value is 0x8100. Other supported values are 0x88a8, 0x9100, and 0x9200.

Starting in Junos OS Release 22.4R1, the QFX5100, QFX5110, QFX5120, QFX5200, and QFX5210 switches support up to four TPID configurations per VLAN. The system supports the following values for the TPID configuration: 0x8100, 0x9200, 0x88a8, and 0x9100. A TPID needs to be defined in the command-line interface for aggregated ethernet interfaces and the ether interfaces for the device, before it can be sent or received.


Routing Engine can handle only the default TPID 0x8100. The traffic destined to the Routing Engine is discarded if the TPID is not 0x8100.


tpids—TPIDs to be accepted on the VLAN. Specify TPIDs in hexadecimal.
