Per-SAP aggregate shapers in the access egress direction operate in a similar fashion to aggregate shapers for access ingress, except that egress traffic goes through the schedulers to the egress port shaper instead of through the schedulers to the fabric port as in the access ingress case. For information on how access egress and access ingress per-SAP shaping is similar, see Access Ingress Per-SAP Aggregate Shapers (Access Ingress H-QoS). For general information on per-SAP shapers, see Per-SAP Aggregate Shapers (H-QoS) On Gen-2 Hardware.
The arbitration of access egress traffic from the per-SAP aggregate shapers to the schedulers is described in the following section.
