Configuring Application Acceleration

This chapter describes how to configure the optimization policies on your WAAS system that determine

the types of application traffic that is accelerated over your WAN.

Note Throughout this chapter, the term WAAS device is used to refer collectively to the WAAS Central

Managers and WAEs in your network. The term WAE refers to WAE appliances, WAE Network Modules

(the NME-WAE family of devices), and SM-SRE modules running WAAS.

This chapter contains the following sections:

• About Application Acceleration, page 1-1

• Enabling and Disabling the Global Optimization Features, page 1-3

• Creating a New Traffic Optimization Policy, page 1-49

• Managing Application Acceleration, page 1-55

About Application Acceleration

The WAAS software comes with over 150 predefined optimization policies that determine the type of

application traffic your WAAS system optimizes and accelerates. These predefined policies cover the

most common type of application traffic on your network. For a list of the predefined policies, see

Appendix 1, “Predefined Optimization Policy.”

Each optimization policy contains the following elements:

• Application definition—Identifies general information about a specific application, such as the

application name and whether the WAAS Central Manager collects statistics about this application.

• Class Map—Contains a matching condition that identifies specific types of traffic. For example, the

default HTTP class map matches all traffic going to ports 80, 8080, 8000, 8001, and 3128. You can

create up to 512 class maps and 1024 matching conditions.

• Policy—Combines the application definition and class map into a single policy. This policy also

determines what optimization and acceleration features (if any) a WAAS device applies to the

defined traffic. You can create up to 512 policies. A policy can also contain a differentiated services

code point (DSCP) marking value that is applied to the traffic and that overrides a DSCP value set

at the application or global level.
