Nodes on the network map

Nodes on the network map can be of the following types:

• A device that is known to the application (an asset). This type of node represents an asset that is listed in the assets table.
• A device that is unknown to the application. This type of node represents a device with a unique IP address or MAC address that is not in the assets table. Such a node may appear on the network map, for example, if network packets are sent using the ping command to the address of a non-existent device. Nodes of unknown devices are displayed individually if their total number does not exceed 100 (according to the current filter settings on the network map). If the number of nodes exceeds this limit, one consolidated node of unknown devices is displayed.
• WAN. This type of node represents devices of a Wide Area Network with which industrial network devices connect.

Displayed information on nodes representing assets

The following information is displayed for nodes representing assets when the network map is maximized:

• Assigned device name.
• Device category icon.
• IP address of the device (If an IP address is not assigned, the MAC address is displayed).
• Asset status icon:
  •  – the asset has the Authorized status.
  •  – the asset has the Unauthorized status.
  •  – the asset has the Archived status.
• The thick line on the left border of a node has one of the following colors depending on the asset's security state:
  • Green signifies the OK security state.
  • Yellow signifies the Warning security state.
  • Red signifies the Critical security state.
• The icon signifies that the router indicator has been set for the asset.

If an asset has the Unauthorized status or has a security state different from the OK state, the node has a red background.

Information displayed on nodes representing unknown devices

The following is displayed for nodes representing unknown devices when the network map is maximized:

• If a node represents one unknown device, the IP address or MAC address of the device is displayed. For a consolidated node of unknown devices (a node that combines more than 100 unknown devices), Unknown devices is displayed.
• icon for unknown devices.
• icon for the status of unknown devices.

Nodes that represent unknown devices have a gray background.

Displayed information on WAN nodes

The following is displayed for WAN nodes when the network map scale is maximized:

• Node name: WAN.
• WAN node icon .
