Data collected by Discovery on network routers and switches

Discovery identifies and classifies information about network routers and switches.

Network routers and switches often have very similar capabilities. It is very common for some switches known as Layer 3 switches to have IP routing. Larger routers with optional modules might accept switching modules. Because of these overlaps and the resulting ambiguity of a particular device's classification, Discovery collects the same data for both routers and switches, if it is available in any given device. For details on how Discovery collects data about connections between network devices and other components, see How Layer 2 Discovery works.
