Configuring Network Settings

This chapter describes how to configure basic network settings such as configuring additional network

interfaces to support network traffic, creating port channel and standby interfaces, creating bridge

interfaces for virtual blades, configuring optimization on WAAS Express interfaces, specifying a default

gateway and DNS servers, enabling the Cisco Discovery Protocol (CDP), and configuring the directed

mode of operation where peer WAEs exchange traffic using UDP encapsulation to avoid firewall

traversal issues.

Note Throughout this chapter, the term WAAS device is used to refer collectively to the WAAS Central

Managers and WAEs in your network. The term WAE refers to WAE appliances, WAE Network Modules

(the NME-WAE family of devices), and SM-SRE modules running WAAS.

Module, see the “Configuring Inline Operation on ANCs” section on page 1-49 or use the AppNav

Cluster wizard as described in the “Creating a New AppNav Cluster with the Wizard” section on

page 1-14.

Configuring Network Interfaces

During initial setup, you chose an initial interface and either configured it for DHCP or gave it a static

IP address, as described in the Cisco Wide Area Application Services Quick Configuration Guide. This

section describes how to configure additional interfaces using options for redundancy, load balancing,

and performance optimization.
