Table 41. 802.1 Authenticator Port Parameters
Parameter Definition
Authenticator Mode Sets the authenticator mode of an
authenticator port. This parameter has the
following values:
802.1x - Specifies 802.1x username and
password authentication. With this
authentication method the supplicant
must provide, either manually or
automatically, a username and password
to the authenticator port. This
authentication method requires 802.1x
client software on the supplicant nodes.
MAC Based - Specifies MAC address-
based authentication. The authenticator
port extracts the source MAC address
from the initial frames received from a
supplicant and automatically sends the
address as both the username and
password of the supplicant to the
authentication server. Supplicant nodes
do not need 802.1x client software for this
authentication method.
Supplicant Mode Sets the supplicant mode of an
authenticator port. The possible settings
are:
Single - Configures the authenticator port
to accept only one authentication. This
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.
