Release Information Statement introduced before Junos OS Release 7.4.
Statement introduced in Junos OS Release 12.1 for PTX Series Packet Transport Switches.
Description For Gigabit Ethernet IQ and IQE interfaces only, bind TPIDs and 802.1Q VLAN tag IDs to
a logical interface.
NOTE: The inner-range vid1–vid2 option is supported on MX Series with IQE
PICs only.
Options inner tpid.vlan-id—A TPID and a valid VLAN identifier.

Range: (most routers) For VLAN ID, 1 through 4094. VLAN ID 0 is reserved for tagging
the priority of frames.
Range: (PTX Series) For VLAN ID, 0 through 4094.
inner-range vid1–vid2—For MX Series routers with Enhanced IQ (IQE) PICs only; specify
a range of VLAN IDs where vid1 is the start of the range and vid2 is the end of the
range.
Range: For VLAN ID, 1 through 4094. VLAN ID 0 is reserved for tagging the priority of
frames.
outer tpid.vlan-id—A TPID and a valid VLAN identifier.
Range: (most routers) For VLAN ID, 1 through 511 for normal interfaces, and 512 through
4094 for VLAN CCC interfaces. VLAN ID 0 is reserved for tagging the priority of
frames.
Range: (PTX Series) For VLAN ID, 0 through 511 for normal interfaces, and 512 through
4094 for VLAN CCC interfaces.
NOTE: Configuring inner-range with the entire vlan-id range consumes system
resources and is not a best practice. It should be used only when a subset of
VLAN IDs of inner tag (not the entire range) needs to be associated with a
logical interface. If you specify the entire range (1–4094), it has the same
result as not specifying a range; however, it consumes Packet Forwarding
Engine resources such as VLAN lookup table entries, and so on.
