MAC Address Learning Limit is a method of port security on Layer 2 port-channel and physical interfaces,
and VLANs. It enables you to set an upper limit on the number of MAC addresses that are learned on an
interface/VLAN. After the limit is reached, the system drops all traffic from a device with an unlearned
MAC address.
