Configuring 802.1x Global Settings
The dot1x protocol includes global parameters that control the client authentication
process that runs between the client and the switch (i.e., authenticator), as well as
the client identity lookup process that runs between the switch and authentication
server. The configuration options for these parameters are described in this section.
