Configuring QoS

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:
Type of Policy
Basic QoS policies
Redirection policies
Policy Based Mirroring
ICMP policies
802.1p, ToS, and DSCP tagging or
mapping policies
Policy Based Routing (PBR)
Access Control Lists (ACLs)
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
Policies can also be used for prioritizing traffic in dynamic link aggregation groups. For more information
about dynamic link aggregates, see
OmniSwitch AOS Release 8 Network Configuration Guide
Description
Prioritizes and polices particular
flows.
Redirects flows to a specific port
or link aggregate ID.
Mirrors ingress and egress
packets to a specific port.
Filters, prioritizes, and/or rate
limits ICMP traffic
Sets or resets the egress 802.1p,
ToS, or DSCP values
Redirects routed traffic.
