Chapter 1 Configuring AppNav
Configuring an AppNav Cluster
Step 5 In the graphical interface view, configure interfaces on the AppNav Controller Interface Module as
needed. For details on how to use the wizard, see the “Configuring Interfaces with the Graphical
Interface Wizard” section on page 1-17.
Step 6 From the Cluster Interface drop-down list, select the interface to be used for intra-cluster traffic.
Step 7 (Optional) To enable swapping of client and WAAS device source IP address fields in intra-cluster
traffic, check the Enable swapping of source IP address in intra-cluster traffic check box.
You may want to enable this option if you are using a port channel for the cluster interface or there is a
load balancing device between the ANC and WN. This option may improve the load balancing of traffic
that the ANC distributes to WNs for optimization because it load balances based on the client IP address
rather than the ANC IP address. (For traffic from the server to the client, it swaps the server IP address
with the ANC IP address.) The Central Manager enables this feature automatically if any existing ANCs
have port channel cluster interfaces.
Step 8 Click OK to save the settings.
Configuring WAAS Node Group Settings
To configure WNG settings, follow these steps:
Step 1 From the WAAS Central Manager menu, choose AppNav Clusters > cluster-name.
Step 2 Click the WAAS Node Groups tab below the topology diagram.
All WNGs in the cluster are listed, showing the name, description, and the WNs contained in the group.
From this list, you can perform the following tasks:
• Edit the settings for a WNG by choosing the WNG and clicking the Edit taskbar icon.
• Delete a WNG by choosing the WNG and clicking the Delete taskbar icon.
• Add a new WNG to the cluster by clicking the Add WAAS Node Group taskbar icon. See the
“Adding a New WAAS Node Group to the Cluster” section on page 1-34.
Step 3 Click the radio button next to the WNG that you want to edit and click the Edit taskbar icon.
Step 4 (Optional) In the Description field, enter a description of the WNG.
Step 5 Click Save to save the settings.
