Service And Network Qos Policies - Alcatel-Lucent 7210 SAS M OS Quality Of Service Manual

Service and Network QoS Policies

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