Data flow: Receiving configuration updates on an iOS device
- An action is taken in the management console that triggers a configuration update for an iOS device. For example, you update the IT policy or assign a new profile or app to the user account.
- Updates are applied in BlackBerry UEM and objects that must be shared with the device are identified.
- The BlackBerry UEM Core performs the following actions:
- Contacts the BlackBerry Infrastructure, through the BlackBerry Router or TCP proxy server, if installed, and the external firewall over port 3101.
- Sends a request through the BlackBerry Infrastructure to the APNs to notify the device that an update is pending.
- The APNs sends a notification to the native MDM Daemon on the iOS device to contact the BlackBerry UEM Core.
- When the native MDM Daemon on the iOS device receives the notification, it contacts the BlackBerry UEM Core, on port 3101 on the external firewall, passing through the BlackBerry Router or TCP proxy server, if installed, to retrieve any pending actions.
- The BlackBerry UEM Core replies with the highest priority action. Priority is given to device actions, such as Delete device data and Lock device. The BlackBerry UEM Core sends only one command at a time. If necessary, additional information is included in the response. If no actions or commands are pending for the device, the BlackBerry UEM Core replies to the device with an idle command.
- The native MDM Daemon on the iOS device performs the following actions:
- Inspects the response from the BlackBerry UEM Core, schedules the command to be processed, and waits for the command to run.
- Sends a response to the BlackBerry UEM Core to update the command status. The status indicates whether the command ran successfully and provides an error message in the event of a failure.
Steps 6 and 7 are repeated until no more pending actions or commands must be performed on the device.
