Configuring a VLAN Demux Underlying Interface
A VLAN demux interface uses an underlying logical interface to receive packets.
 | Note: VLAN demux interfaces support only Gigabit Ethernet, Fast Ethernet, 10-Gigabit Ethernet, or aggregated Ethernet underlying interfaces. |
To determine which VLAN demux interface to use, the VLAN ID is matched against that which the underlying interface receives.
To configure a logical interface as an VLAN demux underlying interface, include the underlying-interface statement at the [edit interfaces demux0 unit logical-unit-number demux-options] hierarchy level and the vlan-id statement at the [edit interfaces demux0 unit logical-unit-number] hierarchy level:
interfaces {demux0 {unit logical-unit-number {vlan-id number;demux-options {underlying-interface interface-name;}family family {address address; }}}}
You can include these statements at the following hierarchy levels:
- [edit]
- [edit logical-system logical-system-name]
- [edit logical-system logical-system-name routing-instances routing-instance-name]
