Can we configure airgroup shared location based discovery on IAP against CPPM server ?


Yes; we could configure airgroup location based discover on IAP as well. This is validated the Shared Location feature of Air Group with CPPM 6.5 with latest versions of 4.1.1.X and 4.1.2.X and above it works with the following modifications while configuring CPPM.

On the IAP ap-name information needs to be configured on the CPPM manually to share the Apple-TV on the specific location (Typical scenario could be such as users to share devices from classrooms or conference room or for a lecture). Device sharing can be done on the basis of user-role or the specific user as well where we have options on the CPPM server.

Please find the following steps on how to make it work from Clear pass:

1. Log in to ClearPass Guest Manager with admin account.
2. On the left pane, go to Configuration, then expand Pages, click on Fields. (On CPPM versions where Pages does not exist, select Fields directly).
3. Click on "airgroup_shared_location", then under it click on Edit.
4. Scroll down to Default Form Display Properties and under it, for "User Interface" option select "Text field" from the drop down box.
5. Scroll down to Advanced Properties. For fields - "Conversion" and "Display Function", select "None" from the drop down for both.
6. Click on Save Changes.
7. The other steps on configuring AP Name for the Shared Location field remain the same (i.e., enter values as "AP-Name=<your AP name>").


Config from Clear Pass server with screen shot

From IAP; we need to make sure airgroup and its corresponding service needs to be enabled.

Configure the auth-server of CPPM details as below from running-config.


In the below config we could notice ap-name is Bldg-Apple-tv which is the same configured and added to Clearpass server.

From the above procedure we could see how to configure and the requirements to build the airgroup location based discovery on IAP against CPPM server.
