Configuring a Static or Dynamic VLAN Demux Subscriber Interface over Aggregated Ethernet
You can configure a subscriber interface using a static or dynamic VLAN demultiplexing (demux) logical interface stacked on an aggregated Ethernet physical interface.
- Configure the aggregated Ethernet interface.
- Configure the number of aggregated Ethernet interfaces
on the router.
See Configuring the Number of Aggregated Ethernet Interfaces on the Device.
- Configure the aggregated Ethernet interface.
- (Optional) Configure LACP.
- (Optional) Configure the minimum number of links.
- (Optional) Configure the link speed.
- (Optional) Configure the aggregated Ethernet logical interface
to support one-to-one active/backup link redundancy or traffic load
balancing.
For general instructions, see Configuring Aggregated Ethernet Link Protection.
- Configure the number of aggregated Ethernet interfaces
on the router.
- Configure the aggregated Ethernet physical interface
as the underlying interface to support the static or dynamic VLAN
demux subscriber interface.
The aggregated Ethernet interface needs to support demultiplexing of incoming traffic to the Ethernet links based on the VLAN ID in the incoming packets.
- Configure the static or dynamic VLAN demux interface.
- For static subscriber interfaces, see Configuring Static Subscriber Interfaces Using VLAN Demux Interfaces.
- For dynamic subscriber interfaces, see Configuring Dynamic Subscriber Interfaces Using VLAN Demux Interfaces in Dynamic Profiles.

Note: VLAN demux interfaces currently support the Internet Protocol version 4 (IPv4) suite (family inet) and the Internet Protocol version 6 (IPv6) suite (family inet6).
- (Optional) Configure subscriber management services on the subscriber interface.
