"By default, MAC address learning is enabled on all interfaces and VLANs on the router. You can control MAC address learning on an interface or VLAN to manage the available MAC address table space by controlling which interfaces or VLANs can learn MAC addresses. Before you disable MAC address learning, be sure that you are familiar with the network topology and the router system configuration. Disabling MAC address learning on an interface or VLAN could cause flooding in the network." https://www.cisco.com/c/en/us/td/docs/wireless/mwr_2941_dc/software_config/guide/3_3/2941_33_Config_Guide/mac_lrn.pdf
