Show Configuration History Cisco Switch

If you've ever needed to see what configuration changes were recently made on a Cisco switch, you can do so by using the configuration change notification and logging feature. This feature keeps a log of what configuration changes were made on the switch and by which user. You can display the contents of this log by running:
'show archive log config all'
If the logging isn't setup (which it isn't by default), you can enable it by running:
conf t
archive
log config
logging enable
hide keys
