Network and service QoS policies

The QoS mechanisms within the 7210 SAS-D and 7210 SAS-Dxp are specialized to cater to the type of traffic on the interface.

The following figure shows that on 7210 SAS-D and 7210 SAS-Dxp, for customer interfaces, there are service ingress and access port egress traffic types, and for access uplink port interfaces, there are network ingress and network egress traffic types.

The 7210 SAS uses the following QoS policies applied to a SAP, access-uplink port, access port to define queuing, queue attributes, meter attributes, and QoS marking interpretation.

The 7210 SAS supports the following major types of service and network QoS policies: Network QoS policies on access-uplink ports, Default network QoS policy (egress) for the 7210 SAS-Dxp, Default network QoS policy (ingress), Network queue policies in access-uplink mode, Service ingress QoS policies, and Service ingress classification.
