Introduction
Hudu Radar can be configured to scan networks from physical or virtual network adapters present on the collector device. Hudu Radar can be configured with multiple network adapters. However, at least one network adapter must be selected to perform any network scans. Hudu Radar will auto-detect the primary/default adapter. This adapter cannot be removed.
The selection of network adapters can be modified from Hudu Radar Settings >> Adapters. You can access the Hudu Radar Settings by navigating to the company using Hudu Radar, clicking into the Hudu Radar section and selecting the Settings tab. Networks from added adapters will be scanned automatically.
In environments where network discovery isn’t available, scanned networks in Hudu Radar can be configured using the collecting machine’s network adapters. Possible configurations include
- One subnet, no VLANs
- Two or more subnets, no VLANs
- Two or more subnets, VLANs
- Multiple adapters
Single Subnet, No VLANs
A network with a single subnet where all devices are accessible at Layer 2. Hudu Radar only needs to be installed on one device within the subnet, and the corresponding adapter should be selected in Hudu Radar to perform the scan.
Two or more subnets, no VLANs
A network with two or more subnets, within each network, all devices are accessible at Layer 2. Hudu Radar should be installed on one device. Network traffic from the device Hudu Radar is installed on should be able to route to the other subnets.
Two or more subnets, VLANs
A network with multiple subnets separated by VLANs. Hudu Radar must be installed on one device connected to a switch port configured as a trunk that carries all required VLANs. Each subnet requires an adapter configured with the corresponding VLAN ID tagging.
Multiple adapters
A network environment where the scanning device has multiple network adapters, each connected to a different subnet or network segment. Hudu Radar should have all relevant adapters selected to ensure scanning covers all connected networks.
