After you define interfaces on the SSR, you can configure QoS policies to control traffic.
This chapter
•
provides an overview of QoS.
•
lists the order in which you perform the various QoS-configuration tasks.
•
discusses establishing the SSR's queuing policy.
•
explains how to associate precedences with IP and IPX flows.
•
discusses configuring QoS policies to define flows.
•
provides details about modifying existing QoS profiles.
What Is QoS?
On the SSR, QoS is a set of parameters that let you do the following:
•
Establish a queuing policy on the SSR to prioritize the SSR's traffic.
•
Associate a precedence with Layer-3/Layer-4 flows. You do so by assigning a
precedence value to each field in those type of flows. The SSR uses the precedence
value assigned to the fields to break ties if packets match more than one flow.
•
Classify Layer-2, Layer-3, and Layer-4 network traffic into one of the following
priorities:
–
control
–
high
