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 118 for information about how to set
up a remote user.
