the port will learn new MAC addresses and turn them to security MAC addresses;
If the amount of security MAC addresses reaches the maximum number, the port
will not be able to learn new MAC addresses and the port mode will be changed
from autolearn to secure.
Note:
The security MAC addresses manually configured are written to the configuration file;

saved, the security MAC addresses can be restored after the switch reboots.
