The QoS mechanism within the 7210 SAS is specialized for the type of traffic on the interface. For customer interfaces, service ingress and access service egress traffic exists, and for IP interfaces, network ingress and network egress traffic exists (as shown in the following figure).
When operating in access-uplink mode, the QoS mechanisms available are similar to network mode, except that network ingress and network egress traffic is associated with access-uplink interfaces instead of network IP interface or network ports (as shown in the following figure).
The 7210 SAS uses QoS policies applied to a SAP, a network port, access port, or access-uplink port to define queuing, queue attributes, meter/policer attributes and QoS marking interpretation.
The 7210 SAS supports the following types of network and service QoS policies: Network QoS policies in network mode, Network queue QoS policies, Service ingress QoS policies, and Service egress QoS policies on 7210 SAS-Mxp, 7210 SAS-R6, and 7210 SAS-R12.
