An aggregate mode shaper provides a single aggregate shaping rate. The rate defines the maximum bandwidth that an adapter card can switch through its fabric interface at any given time. The rate is a bulk value and is independent of the destination or the type of traffic. For example, in aggregate mode, an ingress adapter card might use the full rate to communicate with a single destination adapter card, or it might use the same rate to communicate with multiple egress adapter cards.
Aggregate mode and the aggregate rate apply to fabric shapers that handle combined unicast/BMU traffic, unicast-only traffic, or BMU-only traffic. One aggregate rate sets the rate on all adapter cards. The proportional distribution between unicast and BMU traffic can be fine-tuned using queue-level schedulers, while the to-fabric shaper imposes a maximum rate that ensures fairness on the fabric for traffic from all adapter cards.
When services (IES, VPRN, and VPLS) are enabled, the fabric profile mode for access ingress should be set to aggregate mode.
