Configuring Frames with Particular TPIDs to Be Processed as Tagged Frames

For Gigabit Ethernet IQ interfaces, aggregated Ethernet with Gigabit Ethernet IQ interfaces, Gigabit Ethernet PICs with SFPs Tri-Rate Ethernet copper, and 10-Gigabit Ethernet interfaces, you can configure frames with particular TPIDs to be processed as tagged frames. To do this, you specify up to eight IEEE 802.1Q TPID values per port; a frame with any of the specified TPIDs is processed as a tagged frame; however, with IQ2 and IQ2-E interfaces, only the first four IEEE 802.1Q TPID values per port are supported. The stacked and rewriting Gigabit-Ethernet VLAN Tags are also referred to as Q-in-Q tunneling. To configure the TPID values, include the tag-protocol-id statement:

Review the Platform-Specific Frames with TPIDs Behavior section for notes related to your platform.

You can include this statement at the following hierarchy levels:

All TPIDs you include in input and output VLAN maps must be among those you specify at the [edit interfaces interface-name gigether-options ethernet-switch-profile tag-protocol-id [ tpids ]] or [edit interfaces interface-name aggregated-ether-options ethernet-switch-profile tag-protocol-id [ tpids ]] hierarchy level.

ACX Series

  • On ACX7000 device that supports frames with TPIDs:

    • Use 0x8100 as default TPID, if you do not mention TPID implicitly.

    • You can configure 3 other TPIDs per IFD apart from 0x8100.
