Providing Accurate Scheduling for a Demux Subscriber Interface of Aggregated Ethernet Links


Unlike VLAN subscriber interfaces, enabling link protection is not required for configuring hierarchical CoS on demux interfaces. Instead, we recommend that you enable targeted distribution on the demux interface to provide accurate scheduling for the aggregated Ethernet links.

Before you begin, configure the subscriber interface with aggregated Ethernet:

To provide accurate scheduling for a demux subscriber interface of aggregated Ethernet links:

  1. Enable targeted distribution for the demux interface.

    See Configuring the Distribution Type for Demux Subscribers on Aggregated Ethernet Interfaces.

  2. Enable hierarchical scheduling on the link aggregation bundle.

    See Configuring Hierarchical CoS for a Subscriber Interface of Aggregated Ethernet Links.

  3. (Optional) Enable module redundancy to ensure that CoS resources are provisioned for the aggregated Ethernet links if a module or a link fails. By default, link redundancy is supported.

    See Configuring Link and Module Redundancy for Demux Subscribers in an Aggregated Ethernet Interface.

  4. (Optional) Configure rebalancing periodically or manually for the subscribers. See Configuring Rebalancing of Demux Subscribers in an Aggregated Ethernet Interface.
  5. Attach static or dynamic traffic shaping and scheduling parameters at the aggregated Ethernet logical interface or its underlying physical interface. See:
