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.

As described in the Overview , the Cisco IWAN application (IWAN app) operates through Cisco APIC-EM, as a tool within the APIC-EM browser-based interface.
Separation from APIC-EM Release Schedule
Cisco IWAN app release 1.3.2 introduces a new approach to IWAN app releases. Beginning with this release:
While the release schedule and installation are now handled separately from APIC-EM, the IWAN app continues to be an integral part of APIC-EM and continues to appear in the APIC-EM GUI as before.
System requirements for the APIC-EM continue to apply to the IWAN app.
The release notes describe the software compatible with IWAN app releases, including APIC-EM and Cisco Prime Infrastructure versions.
Access the Cisco IWAN application from the Cisco APIC-EM graphical user interface (GUI). To use the IWAN app, you must first deploy Cisco APIC-EM.
You can deploy Cisco APIC-EM either on a server (bare-metal hardware) or in a virtual machine in a VMware vSphere environment. You can deploy Cisco APIC-EM either as a single host or in a multi-host environment.
Deploy Cisco APIC-EM according to the instructions in the APIC-EM deployment guide, available on the APIC-EM Install and Upgrade Guides page.
Before Installing or Upgrading the IWAN Application
Do the following before installing the IWAN app:
Some versions of the APIC-EM installation package may include an earlier version of the IWAN app.
1. In APIC-EM, select: Settings (gear button) > App Management.
2. Select the Backup & Restore tab.
3. Click the Create New Backup button.
Step 1 Using the Cisco Download Software tool, navigate to Policy and Automation Controllers, and select APIC-EM, or use this direct link:
https://software.cisco.com/download/type.html?mdfid=286208072&flowid=77162
Step 2 Locate the IWAN Application Software option. Download the IWAN application. Note the location of the downloaded file.
Step 3 Start APIC-EM and open the APIC-EM Applications page.
a. Select: Settings (gear button) > App Management
b. Ensure that the Applications tab is displayed.
If a version of the IWAN app has been installed previously, it appears in the Installed Applications list.
c. Note the Drag&Drop Application file here box at the right side of the APIC-EM Applications page.
Step 4 Drag-and-drop the downloaded IWAN app installation file onto the Drag&Drop Application file here box. The new IWAN app appears in the list of applications, and is shown as Disabled.
When upgrading from a previous version of the IWAN app, the earlier version of IWAN continues to appear in the list at this point in the installation.
Step 5 Click Enabled for the new IWAN application. APIC-EM enables the new version. When upgrading from a previous version of the IWAN app, APIC-EM preserves the existing IWAN configuration.
The page indicates that the enable process is in progress. Wait for the process to complete. Installation time depends on the cluster size and other factors.
Step 6 When the installation and enabling are complete, clear the browser cache and refresh the APIC-EM Applications page. The Status column shows that the new IWAN app is enabled, and the Version column shows the new IWAN app version. Any previous version of the IWAN app is removed from the list.
