native-vlan-id
Syntax native-vlan-id number;
Hierarchy Level [edit interfaces ge-fpc/pic/port],
[edit interfaces interface-name]
Release Information Statement introduced in Junos OS Release 8.3.
Statement introduced in Junos OS Release 12.2 for ACX Series Universal Access Routers.
Statement introduced in Junos OS Release 12.3R2 for EX Series switches.
Statement introduced in Junos OS Release 13.2X51-D20 for the QFX Series.
Description Configure mixed tagging support for untagged packets on a port for the following:
• M Series routers with Gigabit Ethernet IQ PICs with SFP and Gigabit Ethernet IQ2 PICs
with SFP configured for 802.1Q flexible VLAN tagging
• MX Series routers with Gigabit Ethernet DPCs and MICs, Tri-Rate Ethernet DPCs and
MICs, and 10-Gigabit Ethernet DPCs and MICs and MPCs configured for 802.1Q flexible
VLAN tagging
• T4000 routers with 100-Gigabit Ethernet Type 5 PIC with CFP
• EX Series switches with Gigabit Ethernet, 10-Gigabit Ethernet, 40-Gigabit Ethernet,
and aggregated Ethernet interfaces
When the native-vlan-id statement is included with the flexible-vlan-tagging statement,
untagged packets are accepted on the same mixed VLAN-tagged port.
NOTE: The logical interface on which untagged packets are received must
be configured with the same VLAN ID as the native VLAN ID configured on
the physical interface, otherwise the untagged packets are dropped.
To configure the logical interface, include the vlan-id statement (matching the
native-vlan-id statement on the physical interface) at the [edit interfaces interface-name
unit logical-unit-number] hierarchy level.
When the native-vlan-id statement is included with the interface-mode statement,
untagged packets are accepted and forwarded within the bridge domain or VLAN that
is configured with the matching VLAN ID.
Starting in Junos OS Release 17.1R1, you can send untagged traffic without a native VLAN
ID to the remote end of the network. To do this, remove the native VLAN ID from the
untagged traffic configuration by setting the no-native-vlan-insert statement. If you do
not configure this statement, the native VLAN ID is added to the untagged traffic.
