MAC Learning Limit

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