Configuring QoS Policy Applications
OmniSwitch AOS Release 8 Network Configuration Guide December 2017 page 26-74
Policy Applications
Policies are used to classify incoming flows and treat the relevant outgoing flows. There are many ways to
classify the traffic and many ways to apply QoS parameters to the traffic.
Classifying traffic can be as simple as identifying a Layer 2 or Layer 3 address of an incoming flow.
Treating the traffic might involve prioritizing the traffic or rewriting an IP address. How the traffic is
treated (the action in the policy rule) typically defines the type of policy:
This section describes how to configure basic QoS policies and 802.1p/ToS/DSCP marking and mapping
policies. Policies used for Layer 2 and Layer 3/4 filters, are commonly referred to as Access Control Lists
(ACLs). Filtering is discussed in Chapter 26, “Configuring QoS.”
Policies can also be used for prioritizing traffic in dynamic link aggregation groups. For more information
about dynamic link aggregates, see Chapter 9, “Configuring Dynamic Link Aggregation.”
