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. VLAN demux subscriber interfaces over aggregated Ethernet physical interfaces are supported only for MX Series routers that have only Trio MPCs installed. If the router has other cards in addition to Trio MPCs, the CLI accepts the configuration but errors are reported when the subscriber interfaces are brought up. |
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:
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]
