• You may need to disable MAC address learning to prevent the MAC address table from being saturated. For example, when your device is being attacked by many packets with different source MAC addresses, it affects the update of the MAC address table. • Because disabling MAC address learning may result in broadcast storms, enable broadcast storm suppression after you disable MAC address learning on a port. Related commands: display mac-address mac-learning. NOTE: When MAC address learning is disabled, the learned MAC addresses remain valid until they age out.

The value is in the range of 0 to 4096. When the argument takes 0, the VLAN is not allowed to learn MAC addresses. Description Use mac-address max-mac-count count to configure the maximum number of MAC addresses that can be learned on a port. 58
