Network and service QoS policies

The QoS mechanism within the 7210 SAS is specialized to cater to the type of traffic on the interface.

The following figure shows that for customer interfaces, there are service ingress and service egress traffic types, and for access-uplink ports and network ports, there are network ingress and network egress traffic types.

The 7210 SAS uses QoS policies applied to a SAP for a service or to an access uplink port or to a network port to define the queuing, queue attributes, meter attributes, and QoS marking/interpretation.

The 7210 SAS supports the following major types of network and service QoS policies: Network QoS policies on 7210 SAS-K 2F6C4T and 7210 SAS-K 3SFP+ 8C network ports and hybrid ports, Network QoS policies on access-uplink ports, Network queue policies, Service ingress QoS policies, and Service egress QoS policies.

The support of different policies varies across different platforms.
