In the topology view, the objects in the main window represent network devices, subnets, and other user-definable objects. The larger circles represent network devices. Individual interfaces are shown as smaller circles inside the network device. Devices may be organized into groups that will appear as annotated, colored rectangles.
The top half of each interface represents inbound traffic and the bottom half represents outbound traffic. The color of each half indicates its status—green indicates normal, orange indicates congestion, and gray indicates the interface is disabled. Inbound and outbound bandwidth values for each interface can be displayed by right-clicking on the device.
Topology View Interface Controls
The View menu contains menu options related to the topology views. These options include:
- Save Image – saves a PNG image of the current topology view
- Fit to View – resizes the topology view to fit all the objects on the topology
- Reset View – resets the pan and zoom of the topology to the default view
- Reset Layout – resets the layout of the topology.
NOTE: Any changes you made to the layout (moving devices) will be reset to the default layout
- Sync to Master Layout – synchronizes your current topology layout with the saved master layout
- Save as Master Layout – saves the current topology layout as the “master layout.”
NOTE: Only users with the admin role can save a master layout
- Show Bandwidths – toggles the display of bandwidth statistics on the topology (shown on the interface icons)
- Show ACLs – toggles the display of icons indicating that an ACL is applied to the interface
- Show Legends – toggles the display of the legend in the lower-left corner of the topology
- Scale Names – toggles a control to maintain a viewable font size for the device name and IP address while zooming in and out in the system view. Default: Scale Names is enabled.
- Force Subnet Display for All Interfaces – toggles a control to override cases where interfaces don’t show its associated subnet cloud. Cases, where this occurs, are with SVI interfaces for which there are no access ports associated with the VLAN and sub-interface parent interfaces with assigned IP addresses. This is available for the admin user only.
- Export Topology to Visio – allows exporting the topology view into a Visio file format. Click on Export Main Topology to export the main topology. Collapsed groups will appear as collapsed groups during the export. To show all devices, click on a group, select Expand All and then export. Click on Export Group Topologies to export each group as a separate tab within Visio. Click to highlight the desired groups to export. Click on Browse to determine the file location for the exported .vdx file and then click on Export. This feature is supported using Visio 2013.
Exporting and Importing a LiveNX Configuration
Configurations can be exchanged between different installed LiveNX clients in order to simplify environment setup. To export a LiveNX configuration, first launch the Management Console from the LiveNX server. Then go to the Manage menu and select Export Configurations. The configuration will be saved to a configuration file.
To import a saved LiveNX configuration file, go to the Manage menu and select Import Configurations. LiveNX must be restarted to load the imported layout.
NOTE: Configuration exporting and importing functions are only available to the Administrator.
LiveNX Technology Tabs
The LiveNX software currently supports QoS, Flow, Routing, IP SLA and LAN. Settings and information for each of these technologies can be accessed by clicking on the technology tabs or by selecting the technology menus.
Usage and Deployment Guidelines
LiveNX software installs on a PC client and enables full control of network devices from the PC’s location. The software updates the running configuration of the device. For the changes to be permanent, you can manually invoke the device’s command to save the settings to the device’s startup configuration.
LiveNX Interface Color Codes
The various colors used in the software indicate a specific status as shown in the table below.
If any error occurs on the graph, a red triangular indicator will appear. Causes of the errors may include missed polling due to dropped packets, a non-responsive device, or other connectivity issues.
Logical Topology (Preview)
The logical topology view allows LiveNX users to focus on a specific section of their topology.
