Displaying And Maintaining Port Security Configuration - H3C S5100-SI Operation Manual

If the amount of security MAC addresses has not yet reach the maximum number, 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.
The security MAC addresses manually configured are written to the configuration file; they will not get
lost when the port is up or down. As long as the configuration file is saved, the security MAC addresses
can be restored after the switch reboots.
