The Auto Smartports feature available on Cisco Catalyst switches allows a port to automatically detect that you’ve attached a device it can recognize (e.g. a Cisco IP Phone, wireless access point, video surveillance camera, etc.)
Then, it runs a macro on that port to apply a "best practice configuration," including QoS, STP, and security settings.
This video introduces you to this exciting feature and gives you a configuration demonstration.
