• macAddressAndPresharedKey mode—The maximum number of PSK users on the port is
the MAC authentication feature's limit on the number of concurrent users or port security's limit
on the number of MAC addresses, whichever is smaller. The actual maximum number of PSK
users on the port also depends on the total number of PSK users that the system can support.
• userLoginSecureExtOrPresharedKey mode—The number of PSK users on the port cannot
exceed the port limit on the number of wireless users, the number of 802.1X users cannot
exceed the 802.1X feature's limit on the number of concurrent users, and the total number of
PSK and 802.1X users cannot exceed port security's limit on the number of MAC addresses on
the port. The maximum number of PSK or 802.1X users also depends on the system
specification.
Working with guest VLAN and Auth-Fail VLAN
An 802.1X guest VLAN is the VLAN that a user is in before initiating authentication.
An 802.1X Auth-Fail VLAN is the VLAN that a user is in after failing authentication.
You can use the 802.1X guest VLAN and 802.1X Auth-Fail VLAN features together with port security
modes that support 802.1X authentication. For more information about the 802.1X guest VLAN and
Auth-Fail VLAN on a port that performs MAC-based access control, see "Configuring 802.1X."

Enabling port security
When port security is enabled, you cannot manually enable 802.1X or MAC authentication, or
change the access control mode or port authorization state. The port security automatically modifies
these settings in different security modes.
Before you enable port security, disable 802.1X and MAC authentication globally.
