Chapter 1 Configuring Application Acceleration
Enabling and Disabling the Global Optimization Features
• Invalid FID optimization—The SMB accelerator optimizes SMB2 clients by locally denying
attempts to access files with invalid file handle values instead of sending such requests to the file
servers.
• Batch Close optimization—The SMB accelerator performs asynchronous file close optimizations on
SMB2 traffic.
To enable the SMB accelerator, check the SMB Accelerator check box in the Enabled Features window.
Note The CIFS accelerator and SMB accelerator are mutually exclusive. Both of these cannot be enabled at
the same time.
To configure the SMB acceleration settings, 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 > SMB Settings.
The SMB Optimization Bypass Settings window appears. (See Figure 1-12.)

Step 3
In the Highest Dialect Optimized drop-down list, choose the highest dialect to optimize. The available
options are:
• NTLM 0.12 or NTLM 1.0
• SMB 2.0
• SMB 2.1
Step 4 In the Highest Dialect Optimized Exceed Action drop-down list, choose the action for the dialects that
are higher than the one chosen as the highest dialect to optimize, as follows:
