'Sticky' secure MAC address learning can be enabled with the following command:

The 'sticky' secure MAC addresses will never age out.
You need to save the running-config to the startup-config to make them truly permanent (or else they will not be kept if the switch restarts).
When you issue the switchport port-security mac-address sticky
command, all current dynamically-learned secure MAC addresses will be converted to sticky secure MAC addresses.
If you issue the no switchport port-security mac-address sticky
command, all current sticky secure MAC addresses will be converted to regular dynamically-learned secure MAC addresses.
