Chapter 1 Configuring Traffic Interception
Configuring AppNav Interception
Step 4 On devices using WAAS versions earlier than 5.0, check the Enable VPATH check box to enable
VPATH interception on the vWAAS device. This check box is not editable on devices using WAAS
versions 5.0 or later.
Note Only one type of interception can be enabled at a time.
Step 5 Click Submit.
To enable VPATH from the CLI, use the interception-method vn-service vpath global configuration
command. The default is disabled. For monitoring and troubleshooting, use the show statistics
vn-service vpath and clear statistics vn-service vpath EXEC configuration commands.
For more information on virtual WAAS configuration, see the Cisco Wide Area Application Services
vWAAS Installation and Configuration Guide.
Configuring AppNav Interception
For WAEs that are part of an AppNav deployment and are configured as WAAS nodes (WNs) in an
AppNav Cluster, you must configure them to use the appnav-controller interception method. These WNs
receive traffic only from the ANCs, not directly from routers. It is on the ANC devices that you configure
an interception method such as WCCP, PBR, or inline to intercept network traffic. For more information
about an AppNav deployment, see Chapter 1, “Configuring AppNav.”
If you create an AppNav Cluster by using the Central Manager wizard, or you add WNs to a cluster
through the AppNav Clusters window, the Central Manager automatically configures WNs with the
appnav-controller interception method. Once the WN is added to a cluster, its interception method
cannot be changed.
To manually configure appnav-controller interception on a WN device, follow these steps:
Step 1 From the WAAS Central Manager menu, choose Devices > device-name.
Step 2 Choose Configure > Interception > Interception Configuration. The Interception Configuration
window appears.
Step 3 From the Interception Method drop-down list, choose appnav-controller to enable the
appnav-controller interception method.
Step 4 Click Submit.
