Cisco Nexus 9000 Series - Disabling 802.1 X Authentication on the Cisco NX-OS Device

Disabling 802.1X Authentication on the Cisco NX-OS Device
You can disable 802.1X authentication on the Cisco NX-OS device. By default, the Cisco NX-OS software
enables 802.1X authentication after you enable the 802.1X feature. However, when you disable the 802.1X
feature, the configuration is removed from the Cisco NX-OS device. The Cisco NX-OS software allows you
to disable 802.1X authentication without losing the 802.1X configuration.
When you disable 802.1X authentication, the port mode for all interfaces defaults to force-authorized regardless
of the configured port mode. When you reenable 802.1X authentication, the Cisco NX-OS software restores
the configured port mode on the interfaces.
