Hi my dear
You can configure an interface to convert the dynamic MAC addresses to sticky secure MAC addresses and to add them to the running configuration by enabling
sticky learning.
To enable sticky learning, enter the
switchport port-security mac-address sticky command.
When you enter this command, the interface converts all the dynamic secure MAC addresses,
including those that were dynamically learned before sticky learning was enabled, to sticky secure MAC addresses
