Shapers are used to control access or network traffic flows through the 7705 SAR.
QoS shapers refer to per-SAP and per-VLAN dual-rate aggregate shapers that operate at the QoS tier 2 level.
Shaper QoS policies refer to policies that contain shaper groups, such as per-customer (MSS) dual-rate aggregate shapers that operate at the QoS tier 3 level.
Configuring a dual-rate aggregate shaper means setting PIR and CIR values. For per-customer (MSS) aggregate shapers, this is done through a shaper group.
Dual-rate aggregate shapers are applied to shaped and unshaped SAP traffic for access ingress and access egress flows, and to shaped and unshaped VLAN traffic for network egress flows.
On a hybrid port, where access and network traffic can share the same physical port, a shaper policy can be applied independently to access egress or network egress traffic.
