As a network engineer, I’ve made heavy use of the [crayon-6458f26173405144816985-i/] and [crayon-6458f2617340b267906839-i/] commands to discover the physical topology of a network without having to physically trace cables. While these are very useful commands, their output is not very human-readable. I built neighborparser.com as a quick-and-easy tool to turn the semi-structured data from these commands […]
