How to enable Spanning Tree Portfast in Cisco Catalyst switch (IOS)

STP Portfast is a feature in Cisco IOS which allows a switchport which is participating in STP to directly transition from Blocking mode to Forwarding mode when a device connects and the link goes up. This can improve the initial connect time and can fix some issues with Windows based devices connecting to the Active Directory domains.
STP Portfast is ideal for ports which connects directly attached devices and certainly not for the ports which connects a hub or a switch. Hence, good to set switchports that directly connect end devices on your Access switch.
