Configuring 802.1X Port Authentication

Configuring
Port Supplicant
Settings for 802.1X
Use the Security > Port Authentication (Configure Interface – Supplicant) page to
configure 802.1X port settings for supplicant requests issued from a port to an
authenticator on another device. When 802.1X is enabled and the control mode is
set to Force-Authorized (see “Configuring Port Authenticator Settings for 802.1X”
on page 356), you need to configure the parameters for the client supplicant
process if the client must be authenticated through another device in the network.
Command Usage
◆ When devices attached to a port must submit requests to another
authenticator on the network, configure the Identity Profile parameters on the
Configure Global page (see “Configuring 802.1X Global Settings” on page 355)
which identify this switch as a supplicant, and configure the supplicant
parameters for those ports which must authenticate clients through the
remote authenticator on this configuration page. When PAE supplicant mode is
enabled on a port, it will not respond to dot1x messages meant for an
authenticator.
◆ This switch can be configured to serve as the authenticator on selected ports
by setting the Control Mode to Auto on the Authenticator configuration page,
and as a supplicant on other ports by the setting the control mode to Force-
Authorized on that configuration page and enabling the PAE supplicant on the
Supplicant configuration page.
Parameters
These parameters are displayed:
◆ Port – Port number.
◆ PAE Supplicant – Enables PAE supplicant mode. (Default: Disabled)
If the attached client must be authenticated through another device in the
network, supplicant status must be enabled.
Supplicant status can only be enabled if PAE Control Mode is set to “Force-
Authorized” on this port (see “Configuring Port Authenticator Settings for
802.1X” on page 356).
PAE supplicant status cannot be enabled if a port is a member of trunk or LACP
is enabled on the port.
◆ Authentication Period – The time that a supplicant port waits for a response
from the authenticator. (Range: 1-65535 seconds; Default: 30 seconds)
◆ Held Period – The time that a supplicant port waits before resending its
credentials to find a new an authenticator. (Range: 1-65535 seconds;
Default: 30 seconds)
◆ Start Period – The time that a supplicant port waits before resending an
EAPOL start frame to the authenticator. (Range: 1-65535 seconds; Default: 30
seconds)
