Nodes on the topology map

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

• A device that is known to the application. This type of node represents a device that is listed in the devices table.
• Unmanaged switch. This type of node represents a device whose MAC- and IP addresses are either unavailable or unknown. Due to its lack of address information, this device cannot be added to the devices table. However, such a device can still be linked to other devices. For instance, this type of node may appear on the topology map if active polling detects multiple connections of different devices to one port of the same device. If this is the case, the application determines that an unidentified switching device (such as a hub) is present in the network, and automatically creates a node for this device. No more than 1,000 unmanaged switches can be added to the application.

  If you are able to identify the MAC- and/or IP address of a node for an unmanaged switch, you can use this unmanaged switch node to manually add a new device to the devices table.

Displayed information on nodes representing devices

The following information is displayed for nodes representing known devices when the topology map scale is maximized:

• Assigned device name.
• Device category icon.
• Network name or address of the device (if an IP address is not assigned, the MAC address is displayed).
• Various icons depending on fulfillment of the following conditions:
  • If the router indicator has been set for the device.
  • If an EPP application is installed on the device (the color of the icon depends on the connection state).
  • If the device has the Archived status.
• The thick line on the left border of a node has one of the following colors depending on the device's security state:
  • Green signifies the OK security state.
  • Yellow signifies the Warning security state.
  • Red signifies the Critical security state.

If a device has the Unauthorized status, the node has a red background.

Displayed information on nodes representing unmanaged switches

The following information is displayed for the nodes representing unmanaged switches when the topology map scale is maximized:

• Defined node name.
• Unmanaged switch icon.

Nodes representing unmanaged switches have a gray background.
