Netcordia's Netcordia's Periscope “network analysis appliance” is a standalone expert system built on Linux and other open source software. The Periscope is plugged into a network and let to run for a day or so, at which point it should begin to display meaningful, concise, prioritized data… on its “issues” interface: versions of Cisco IOS with memory leaks, duplex-mode errors between PCs and switches, and unclean switch trunking, for example. Netcordia offers Periscope in a $24,900 configuration that supports up to 100 switches, and a $49,000 package supporting 250 switches.
