You can create Layer-2 groups and apply dynamic map filters to layer-2 maps so that the maps update dynamically, each time device information is changed.
As a part of selecting (filtering) devices to display in the dynamic topology maps, you use Map Devices and Connected Devices selection filters to build the a custom map. For example, using the Map Devices filtering options, you can select devices in the IP range of 10.0.0.1 - 10.0.0.100 to appear on a map. Any device added to the network, within the range, will be added to the map. You can also apply Connected Devices filters to show devices connected to the core mapped devices. For example, you can filter a map to show all servers connected to switches on the topology map.
This feature helps ensure that your layer-2 topology maps are up-to-date with the most recent network configuration.
Use the The Layer-2 Group Properties dialog to:
To create a new layer-2 group and manage group map settings:
- or -
On the WhatsUp Gold web interface, in Map View, right-click inside the map. From the right-click menu, click New > New Layer-2 Group. The Layer-2 Group Properties dialog appears.
Devices tab
Select the Update Mode:
Use the Map Devices and Connected Devices boxes to design a filter for the devices you want to include on the map. Click Edit to open the Edit Devices Filter dialog and make device filter selections. For more information, see Configuring Device Filters.
If you want to see layer-2 links for devices in the map, select the Show Layer-2 Links option.
If you want to see association links for devices in the map, select the Show Association Links option.
Layout tab
To understand the layout modes, you must be familiar with the layout strategy used by the WhatsUp Gold topology engine. For each map, the topology viewer automatically selects a root device, which becomes the starting point of the diagrams. The root device is selected based on finding the device on the diagram with the most network connections.
Using the connectivity model, the topology viewer sets the root as the parent and then assigns all connected devices as children. This process continues until all devices on the topology map are given a parent/child relationship.
With the parent/child relationships calculated, the topology viewer provides three layout modes for any topology map. These modes describe the manner in which each child node (or device) is given its position on the topology map. The layout modes are described as follows:
Note: When increasing the node angle, if a large number of devices are shown connected to one parent, the radial layout may overlap (make a full circle). In this case you may need to decrease the node angle and increase the level spacing.
Direction. This setting indicates the placement of the root device and the direction the children will be placed from the root device.
Alignment. This setting indicates the placement of the root (or parent) device in relationship to its children.
Level Spacing. This setting dictates the amount of space between the parent and child devices. Increase this value to provide more spacing between the parent and children devices.
Node Spacing. This setting dictates the amount of space between each child (or sibling) devices. Increase this value to create more space between sibling devices.
