MAC address learning disable works only on the port-security enabled ports. When MAC learning is disabled on a port, already existing dynamic and sticky MAC addresses are flushed and only the static MAC addresses are retained. Also, the new static MAC address configurations are accepted. Starting from Release 10.5.4.4, you can disable dynamic MAC address learning on the virtual interfaces.

Example (LAG) 
OS10(config)# interface vlan 2
OS10(conf-if-vl-2)# mac-learn disable
Example (VLAN) 
OS10(config)# interface port-channel 1
OS10(conf-if-po-1)# switchport port-security
OS10(conf-if-po-1-port-sec)# mac-learn disable
