Depending on the VLAN rewrite operation, you configure the rewrite operation for
the interface in the input VLAN map, the output VLAN map, or in both the input
VLAN map and the output VLAN map. Table 60 on page 668 shows what rewrite
operation combinations you can configure. "None" means that no rewrite operation
is specified for the VLAN map.

As well as knowing if the VLAN rewrite operation is valid, and whether it 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 669.

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 (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
