Note that:
z For 802.1X to take effect on a port, you must enable it both globally and on the port.
z You can enable 802.1X and specify the port authorization mode, port access control method, and
maximum number of users for a port in both system view and interface view. For detailed
configuration, refer to Configuring 802.1X for a Port . The only difference between global
configurations and configurations on a port lies in the applicable scope. If both a global setting and
a local setting exist for an argument of a port, the one configured later takes 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 different authentication servers.
