Port-based Network Access Control

Port-based Network Access Control (IEEE 802.1x) uses the RADIUS

protocol to control who can send traffic through and receive traffic from a

switch port. With this feature, the switch does not allow an end node to

send or receive traffic through a port until the user of the node has logged

on by entering a username and password that the RADIUS server has

validated.

The benefit of this type of network security is obvious. This feature can

prevent an unauthorized individual from connecting a computer to a switch

port or using an unattended workstation to access your network

resources. Only those users to whom you have assigned valid usernames

and passwords are able to use the switch to access the network. See

“Setting Up a Dial-In User” on page 116 for information about how to set

up a remote user.
