Identify and Configure a WWAN Modem for PCI Passthrough

App Direct (PCI passthrough) assigns a WWAN modem adapter exclusively to a single application. The application owns the hardware directly, and the modem is not shared with EVE-OS (Edge Virtualization Engine) or other applications. Use this configuration when an application requires direct, low-latency access to a cellular modem without going through the EVE-OS network stack.

​

Prerequisites

• The node is onboarded and has Online status.
• A WWAN modem is physically present on the node and detected by EVE-OS.
• The target application is designed to control a cellular modem directly.

​

Identify the WWAN Modem on a Node

1. In the sidebar, select Infrastructure > Fleet > Nodes.
2. Select the node name to open the node detail page.
3. Select the Adapters tab.
4. Locate the adapter with type WWAN in the Network Adapters list.

The adapter row shows the modem’s current Interface Usage, physical label, logical label, and connection status. If EVE-OS has reported modem information, a Modem section displays the Manufacturer, Model, Firmware version, IMEI, and Control Protocol.

​

Configure the Adapter for App Direct (PCI Passthrough)

1. On the Adapters tab, locate the WWAN adapter.
2. In the Usage column, select the current value to open the Interface Usage dropdown.
3. Select App Direct.
4. Select Save to apply the configuration.

The adapter is now reserved for a single application. EVE-OS will not use it for management or shared network traffic.

Assign the Adapter to an Application

After setting a WWAN adapter to App Direct, it becomes available as a direct-attach option when deploying an application instance. During application instance deployment, select the adapter by its logical label in the I/O adapter assignment step. Note: An adapter set to App Direct cannot be used as a VLAN parent. Only Management, App Shared, and VLANs Only adapters are valid VLAN parent interfaces.

​

Add WWAN to a Hardware Model

To include WWAN adapters in a hardware model definition (for documentation and onboarding use), add a WWAN I/O member to the model. See Hardware Models and set the Type to WWAN when adding the I/O member.
