You must know whether the VLAN rewrite operation is valid and is applied to the input
VLAN map or the output VLAN map. You must also know whether the rewrite operation
requires you to include statements to configure the inner and outer TPIDs and inner and
outer VLAN IDs in the input VLAN map or output VLAN map. For information about
configuring inner and outer TPIDs and inner and outer VLAN IDs, see “Configuring Inner
and Outer TPIDs and VLAN IDs” on page 135.

Configuring Frames with Particular TPIDs to Be Processed as Tagged Frames
Copyright © 2012, Juniper Networks, Inc.
For Gigabit Ethernet IQ interfaces, aggregated Ethernet with Gigabit Ethernet IQ interfaces,
Gigabit Ethernet PICs with SFPs (except the 10-port Gigabit Ethernet PIC and the built-in
Gigabit Ethernet port on the M7i router), and MX Series router Gigabit Ethernet, 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. To configure the TPID values, include the
tag-protocol-id statement:
tag-protocol-id [ tpids ];

You can include this statement at the following hierarchy levels:
• [edit interfaces interface-name gigether-options ethernet-switch-profile]
• [edit interfaces interface-name aggregated-ether-options ethernet-switch-profile]
