The configuration log will track each configuration command that is applied, who applied the command, the parser return code for that command, and the time that the command was applied. This feature also adds a notification mechanism that sends asynchronous notifications to registered applications whenever the configuration log changes.
We use a network management tool called NetMRI and this tool is able to examine all the routers in the network on a periodic basis and to report all routers whose configuration appears to have changed but not saved to NVRAM.
