Authentication Method and Port Mode Support
The following table shows which combinations of authentication method and port 
mode are supported. 
Legend:
†—The port mode also supports the guest VLAN and RADIUS-VLAN assignment.
N/S—The authentication method does not support the port mode.
NOTE Web-based authentication requires TCAM support for input traffic classification 
and can be supported only by the full multi-sessions mode. You can simulate the 
single-host mode by setting Max Hosts parameter to 1 in the Port Authentication 
page.
