The documentation set for this product strives to use bias-free language. For the purposes of this documentation set, bias-free is defined as language that does not imply discrimination based on age, disability, gender, racial identity, ethnic identity, sexual orientation, socioeconomic status, and intersectionality. Exceptions may be present in the documentation due to language that is hardcoded in the user interfaces of the product software, language used based on RFP documentation, or language that is used by a referenced third-party product.

The IWAN app for DNA Center operates largely in the same way as it did in its previous release on APIC-EM, but there are some changes to note. The IWAN app integrates the DNA Center functionality, such as defining sites and managing Cisco IOS images.
Tip | Some tasks involve steps in DNA Center and in the IWAN app. Open DNA Center and IWAN app in two separate tabs of a browser to switch between them easily. Refresh the page if necessary to reflect updated information. |
The IWAN App High-level Overview provides a summary of tasks related to the IWAN app, and where to execute them.

---|---|---|---|
Global network settings |
On the IWAN app home page, the Monitor & Troubleshoot option has been replaced with Create Sites & Configure Global Settings. This option opens the DNA Center > Design > Network Settings page for configuring global settings. Mandatory global settings for using the IWAN app:
Mandatory global settings for DNA Center:
Each node in the network hierarchy configured in DNA Center inherits the settings of the parent node, but you can select any node and override the inherited settings.
|
||
DNA Center behind NAT |
DNA Center behind NAT is supported. In the IWAN app > Configure Hub Site & Settings > System tab, configure the DNA Center NAT/proxy IP. The default NAT port (80) is used. In this release, after the NAT address is set, it cannot be changed.
|
||
Creating sites and network hierarchy |
In DNA Center > Design > Network Hierarchy, define the network hierarchy, including sites, buildings, and floors. The IWAN app uses the leaf nodes (terminal nodes) of the hierarchy as sites within the IWAN app. These may be either buildings or floors. For example, if the following site locations are defined in DNA Center…
...the IWAN app presents the following sites:
To distinguish nodes with the same name, the IWAN app displays the full path, where necessary, when selecting sites. Example:
|
||
Setting site location |
In DNA Center > Design > Network Hierarchy, select a site or building and configure the geographic location. The location is shown in the IWAN app map view.
|
||
Inheritance of settings, IWAN app uses only global settings |
Each node in the network hierarchy (defined in DNA Center > Design > Network Hierarchy) inherits settings from the parent node.
|
||
Configuring a hub site |
In DNA Center, define hub sites and locations. When configuring a hub site, in the IWAN app > Configure Hub Site & Settings > IWAN Aggregation Site tab, use the dropdown menu to select a hub site from the list of sites configured in DNA Center. |
||
Adding greenfield devices to branch sites |
In the IWAN app > Sites > Devices tab, click the Add Greenfield Device button. This opens DNA Center > Provision > Devices > Inventory. Click Unclaimed Devices and follow the procedure for adding a new greenfield device (Workflow Overview: Adding a Greenfield Device to a Branch Site). |
||
Adding brownfield devices to branch sites |
When adding a brownfield device, select the site name in the IWAN app > Sites > Devices tab > Site Name column. During provisioning, the IWAN app communicates this site assignment for the brownfield device to DNA Center, and the assigned site will appear in the device inventory. |
||
Deleting a site in the IWAN app |
Deleting a site in the IWAN app changes the status of the associated devices in DNA Center.
|
||
Cisco IOS image management |
Manage Cisco IOS images to be used for provisioning new devices, in .
