Usage guidelines
You must disable global 802.1X and MAC authentication before you enable port security on a port.
Enabling or disabling port security resets the following security settings to the default:
• 802.1X access control mode is MAC-based.
• Port authorization state is auto.
When online users are present on a port, disabling port security logs off the online users.
