6. Configure the following parameters as necessary:
Supplicant Mode
This parameter sets the supplicant mode of an authenticator port and
can take the following values:
ˆ Single: Configures the port to accept only one authentication. This
authenticator mode should be used together with the piggy-back
mode. When an authenticator port is set to the Single mode and
the piggy-back mode is disabled, only the one client who is
authenticated can use the port. Packets from or to other clients on
the port are discarded. If piggy-back mode is enabled, other clients
can piggy-back onto another client’s authentication and so be able
to use the port.
ˆ Multiple: Configures the port to accept up to 20 authentications.
Every client using an authenticator port in this mode must have a
username and password combination.
Port Control
The possible settings are:
Auto - Enables 802.1x port-based authentication and causes the port
to begin in the unauthorized state, allowing only EAPOL frames to be
sent and received through the port. The authentication process begins
when the link state of the port changes or the port receives an EAPOL-
Start packet from a supplicant. The switch requests the identity of the
client and begins relaying authentication messages between the client
