Maps and diagrams of the network are essential to visualize, understand and track change in the environment. With networks growing at exponential speeds, static mapping of devices might no longer be able to keep up with the ever-changing environment. The network management software must be able to automate resource discovery and mapping. Integrated map-based configuration management and troubleshooting tools are additional pluses.
A dynamic map is usually comprised of data-rich smart objects, which can automatically update themselves as the network changes. You can also schedule network discovery tools to run scans and update the maps at pre-configured intervals. A dynamic map is especially useful in virtual environments, where virtual machines can be added with ease.
Visual depiction is an important feature in a dynamic map – the map should be presented in an easy-to-read format, with the capability to access information quickly.
While Layer 3 dynamic maps show details on IP routing, Layer 2 maps are essential to show switch level details, including bridge ports and VLAN-related information. Network mapping software ideally uses both layer 2 and layer 3 maps for a detailed visual representation of the network.
WhatsUp Gold offers dynamic, self-discovering L2 and L3 maps with zoom and highlight features for better detailing, and correlated layer 2 connectivity with layer 3 IP addressing.
