Port Authentication
In port-based authentication mode, when 802.1X is enabled globally and on the port,
successful authentication of any one supplicant attached to the port results in all users being
able to use the port without restrictions. At any given time, only one supplicant is allowed to
attempt authentication on a port in this mode. Ports in this mode are under bidirectional
control. This is the default authentication mode.
