Configuring an AppNav Cluster
– 32 WNGs
• All ANCs in an ANCG must have the same set of ANCs and WNGs in their configuration.
• All WNs in one WNG must have identical optimization policies configured on them.
• AppNav class maps and policies can be configured only at the cluster level, not at the device level,
from the Central Manager. At the device level, class maps and policies may only be viewed.
• You can define the following maximum policy entities within a service context:
– 1024 match conditions
– 512 AppNav class maps
– 64 rules per AppNav policy
– 64 AppNav policies, though only one policy is actively bound to the service context and used
for flow distribution on a given ANC
• There is no fail-to-wire capability on AppNav Controller Interface Module interfaces configured in
bridge groups for inline mode, which would allow traffic to bypass the interface if the device fails
or loses power. Therefore, if you are using inline mode, we recommend that you deploy two or more
AppNav Controller appliances to provide high availability.
• Virtual blades are not supported on WAAS appliances that are operating as AppNav Controllers.

Task Flow for Configuring an AppNav Cluster
You must complete the following steps to configure an AppNav Cluster:
1. Install and configure the individual ANC and WN devices with basic network settings. See the
“Configuring WAAS Device Interfaces” section on page 1-11.
2. Use the Central Manager AppNav Cluster Wizard to create a cluster and configure the interception
mode, configure cluster settings, choose cluster devices, configure traffic interfaces, and configure
WCCP settings if you are using WCCP. See the “Creating a New AppNav Cluster with the Wizard”
section on page 1-14.
