One report shows that two-thirds of network engineers regularly troubleshoot problems in an unfamiliar infrastructure, with unclear visibility, old documentation, and scattered connections. Not only does this lengthen the time it takes to resolve network problems, but it also involves a whole lot of guesswork, which can prevent getting to the root cause of the issue. This means that it may stick around for awhile.
With so many people in this situation, Fluke Networks came up with some handy visualization tools, which are available in the new OptiView XG Network Analysis Tablet v9 software. This version includes two information packed features, the new Network Navigator function and the improved Path Analysis tool.
Since visualizing the network is such an obstacle for troubleshooting, an as-built, usable network map would be great for getting a handle on how things are connected and configured. Using CDP and LLDP data, The Network Navigator allows network engineers to simply connect to a root switch and instantly see all connected switches and hosts, with additional drill down data available per connection.
This data is critical when troubleshooting problems because it instantly gives network engineers an as-built map, allowing them to see what is really there, rather than following cables and relying on old documentation.
