You can discover devices on the network by navigating to** DeviceHub **> **Asset Discovery**. 

# Enable/Disable Device Discovery

:::hint{type="warning"}
**Important**: To discover devices on CIP, your firewall must allow incoming UDP packets on 58107. Once you enable discovery for CIP, a firewall rule in Belden Horizon Data Operations will automatically be created to allow UDP messages on port 58107. When device discovery for CIP is disabled, the firewall rule will be automatically deleted. You can view this rule on the Firewall page, but you can't edit or delete it. See [Manage Firewall Rules](docId\:hidOfex39BCe2ZiaWWvh2) to learn more.

You can enable and disable discovery of devices that are connected to your network. Use Asset Discovery to discover which nodes are for edge devices.

To enable asset discovery, you will first need to select which interfaces to search on. Open the menu for Interfaces to select them.

# Discover Devices on the Network

Depending on the enterprise, Belden Horizon Data Operations may become lost among the thousands of devices in the private network. You can use Belden Horizon Data Operations with VGA/HDMI to discover devices. 

## Belden Horizon Data Operations with VGA/HDMI

If the system is running normal Belden Horizon Data Operations, it can be discovered using TUI (Terminal User Interface) access. Connect a monitor to the Belden Horizon Data Operations IPC and the terminal shows the IP address of the device. See [Access the Terminal User Interface](docId\:Xxx3UwRZpVqHQsxTdC4jd).
