Chapter 1 Configuring Application Acceleration

Enabling and Disabling the Global Optimization Features

The global optimization features determine if TFO Optimization, Data Redundancy Elimination (DRE),

and Persistent Compression are enabled on a device or device group. By default, all of these features are

enabled. If you choose to disable one of these features, the device will be unable to apply the full WAAS

optimization techniques to the traffic that it intercepts.

In addition, the global optimization features include each of the following application accelerators:

EPM, CIFS, HTTP, MAPI, NFS, SSL, SMB, ICA, and video. By default, all of the application

accelerators are enabled except SMB. Encrypted MAPI is also not enabled by default. The application

accelerators also require specific licenses to operate. For information on installing licenses, see the

“Managing Software Licenses” section on page 1-3.

You must enable the accelerator on both of the peer WAEs at either end of a WAN link for all application

accelerators to operate.

To enable or disable a global optimization feature, follow these steps:

Step 1 From the WAAS Central Manager menu, choose Devices > device-name (or Device Groups >

device-group-name).

Step 2 Choose Configure > Acceleration > Enabled Features.

The Enabled Features window appears. (See Figure 1-1.)

Note For a WAAS Express device, only a subset of the standard features are available. (See

Figure 1-2.)
