Note that:
z For 802.1X to take effect on a port, you must enable it both globally in system view and for the port
in system view or Ethernet interface view.
z You can also enable 802.1X and set port access control parameters (that is, the port access control
mode, port access method, and the maximum number of users) for a port in Ethernet interface view.
For detailed configuration, refer to
Configuring 802.1X for a Port. The only difference between
configuring 802.1X globally and configuring 802.1X for a port lies in the applicable scope. If both a
global setting and a local setting exist for an argument of a port, the last configured one is in effect.
z 802.1X timers only need to be changed in special or extreme network environments. For example,
you can give the client timeout timer a higher value in a low-performance network, give the quiet
timer a higher value in a vulnerable network or a lower value for quicker authentication response, or
adjust the server timeout timer to suit the performance of the authentication server.
