Disabling MAC address learning
Sometimes, you might need to disable MAC address learning to prevent the MAC address table from
being saturated, for example, when your device is being attacked by a large amount of packets with
different source MAC addresses.
When MAC address learning is disabled, the learned MAC addresses remain valid until they age out.
