802.1X Port Authentication
The Port Authentication page enables configuration of 802.1X parameters for each 
port. Since some of the configuration changes are only possible while the port is 
in Force Authorized state, such as host authentication, it is recommended that you 
change the port control to Force Authorized before making changes. When the 
configuration is complete, return the port control to its previous state. 
NOTE A port with 802.1x defined on it cannot become a member of a LAG.
