If you are like most businesses you may already have an Active Directory infrastructure deployed and thus you already have the necessary software and licenses required to setup a basic RADIUS server using Network Policy Server (NPS) which can be used to authenticate network administrators on your Cisco IOS equipment for management purposes. Traditionally this has been done using the Cisco Access Control Server (ACS) which of course is fairly expensive and is typically out of the price range for most small & medium sized businesses. Configuring Cisco devices to authenticate management users via RADIUS is a great way to maintain a centralized user management base.
