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]
