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.

  1. Configure the aggregated Ethernet interface.
    1. Configure the number of aggregated Ethernet interfaces on the router.

      See Configuring the Number of Aggregated Ethernet Interfaces on the Device.

    2. Configure the aggregated Ethernet interface.

      See Configuring an Aggregated Ethernet Interface.

    3. (Optional) Configure LACP.

      See Configuring LACP for Aggregated Ethernet Interfaces.

    4. (Optional) Configure the minimum number of links.

      See Configuring Aggregated Ethernet Minimum Links.

    5. (Optional) Configure the link speed.

      See Configuring Aggregated Ethernet Link Speed.

    6. (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.

  2. 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.

    See Configuring a VLAN Demultiplexing Interface.

  3. Configure the static or dynamic VLAN demux interface.Note

    VLAN demux interfaces support the Internet Protocol version 4 (IPv4) suite (family inet) and the Internet Protocol version 6 (IPv6) suite (family inet6).

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

  4. (Optional) Configure subscriber management services on the subscriber interface.
