Chapter 1 Configuring Network Settings
Configuring Network Interfaces
On WAAS devices with versions earlier than 5.0, the default gateway is configured within the interface
settings for each interface.
Configuring Port-Channel Settings
The WAAS software supports the grouping of up to four (eight on AppNav Controller Interface
Modules) physical network interfaces into one logical interface called a port channel. After you
configure this port-channel interface, you must associate physical interfaces with the port channel.
You can configure up to four port-channel interfaces (seven on AppNav Controller Interface Modules).
This capability also provides interoperability with Cisco routers, switches, and other networking devices
or hosts supporting EtherChannel, load balancing, and automatic failure detection and recovery based
on each interface’s current link status. EtherChannel is also referred to as a port channel.
You can use a port channel in standby interface, a bridge virtual interface (BVI) for a virtual blade, or
as a member of an inline bridge group on an AppNav Controller Interface Module. For more information
on configuring a BVI, see the “Bridging to a Virtual Blade Interface” section on page 1-17. For more
information on configuring a bridge group on an AppNav Controller Interface 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.
The following operating considerations apply to a port-channel virtual interface:
• A physical interface can be a member of a port channel or a standby group, but not both.
• You cannot assign an IP address to both a port channel and a standby group. Only one logical
interface can be configured with an IP address.
• All port-channel member interfaces must have the same port bandwidth.
• Port-channel settings are not applicable to vWAAS devices.
• You cannot include a built-in Ethernet port and a port on a Cisco Interface Module in the same
port-channel interface.
Note You must disable autoregistration if the device has only two interfaces and both device interfaces are
configured as port-channel interfaces.
Configuring a port-channel interface differs, depending on the version of the WAAS device that you are
configuring. See one of the following topics:
• Configuring a Port-Channel Interface on a Device with Version 5.0 or Later, page 1-10
• Configuring a Port-Channel Interface on a Device Earlier than Version 5.0, page 1-11
Configuring a Port-Channel Interface on a Device with Version 5.0 or Later
To configure a port-channel interface for devices with WAAS version 5.0 or later, follow these steps:
Step 1 From the WAAS Central Manager menu, choose Devices > device-name.
Step 2 Choose Configure > Network > Network Interfaces. The Network Interfaces window for the device
appears.
Step 3 In the taskbar of the lower area, click the Create Logical Interface icon. The Create Logical Interface
window appears.
