Defining Host and Session Authentication 
The Host and Session Authentication page enables defining the mode in which 
802.1X operates on the port and the action to perform if a violation has been 
detected.
The 802.1X modes are:
• Single—Only a single authorized host can access the port. (Port Security 
cannot be enabled on a port in single-host mode.)
• Multiple Host (802.1X)—Multiple hosts can be attached to a single 802.1X-
enabled port. Only the first host must be authorized, and then the port is 
open for all who want to access the network. If the host authentication fails, 
or an EAPOL-logoff message is received, all attached clients are denied 
access to the network.
• Multiple Sessions—Enables the number of specific authorized hosts to 
access the port. Each host is treated as if it were the first and only user and 
must be authenticated. Filtering is based on the source MAC address.
To define 802.1X advanced settings for ports:
STEP 1 Click Security > 802.1X > Host and Session Authentication. The Host and 
Session Authentication page displays.
802.1X authentication parameters are described for all ports. All fields except the 
following are described in the 
Edit Host and Session Authentication 
page.
• Status—Displays the host status. An asterisk indicates that the port is either 
not linked or is down. The options are:
- Unauthorized—Either the port control is Force Unauthorized and the 
port link is down, or the port control is Auto but a client has not been 
authenticated via the port.
- Force-Authorized—Clients have full port access.
- Single-host Lock—Port control is Auto and only a single client has been 
authenticated by using the port.
