1.5 Setting the Port Security Mode

Before setting the port security mode, ensure that:
802.1x is disabled, the port access control method is macbased, and the port
access control mode is auto.
MAC authentication is disabled.
Otherwise, you will see an error message and your configuration will fail.
On the other hand, after setting the port security mode on a port, you cannot change
any of the above configurations.
Note:
With port security disabled, you can configure the port security mode but your
configuration does not take effect.
With port security enabled, you can change the port security mode of a port only
when the port is operating in noRestrictions mode, the default mode. You can use
the undo port-security port-mode command to restore the default port security
mode.
You cannot change the port security mode of a port when any user is present on the
port.
Configuration of port security mode and aggregation are mutually exclusive. You
cannot configure both of them on a port.
