Required
Disabled by default.
1. Enabling port security resets the following configurations on a port to the bracketed defaults. Then,
values of these configurations cannot be changed manually; the system will adjust them based on

802.1X (disabled), port access control method (macbased), and port authorization mode (auto)
MAC authentication (disabled)
2. Disabling port security resets the following configurations on a port to the bracketed defaults:
Port security mode (noRestrictions)
802.1X (disabled), port access control method (macbased), and port authorization mode (auto)
MAC authentication (disabled)
3. Port security cannot be disabled when a user is present on a port.
NOTE:
For more information about 802.1X configuration, see the chapter “802.1X configuration.”
For more information about MAC authentication configuration, see the chapter “MAC authentication
