IEEE 802.1X: Practical Port Control for Switches

Article Description

Whether there are 500 or 50,000 access (user) ports in a network, it's just not practical to think about how to control what or who can or cannot use a port. The IEEE 802.1X standard may just change that line of thinking.


Campus networks have many features and parameters that must be managed by network administrators in order to facilitate a reliable and scalable network. Many times, the balancing of these parameters does not allow for a great level of control concerning who and what is plugged into the ports of the network devices. The IEEE 802.1X standard offers a standardized method for controlling port access in a central location on a user or device basis. 802.1X is one of many emerging standards that are helping facilitate the control of campus networks.
