Netwrix Change Reporter named excellent at doing what it is intended to do!
Netwrix Auditing Platform Architecture
Network devices, such as routers, switches, firewalls, and others, are the core infrastructure of every computer network and without correct configuration settings the entire network or any part of it can become unreachable, underperforming, vulnerable to external attacks or become a source of numerous connectivity issues. And no network can live without dynamic changes that occur daily: new devices appear, old devices become obsolete, configuration changes are made by network administrators, including accidental and unauthorized changes.
Netwrix Network Infrastructure Change Reporter is a network device auditing and reporting tool. Currently the product is in BETA and allows to report only on the limited number of device configuration settings, such as Network Device, Network Interface, Gateways, Device IPs, MAC Address and several others.
