Description
Use
mac-address mac-learning disable
to disable MAC address learning globally or on an interface.
Use
undo mac-address mac-learning disable
to enable MAC address learning globally or on an
interface.
By default, MAC address learning is enabled.
Follow these guidelines when you configure MAC address learning:
•
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 a great deal of packets with
different source MAC addresses, the update of the MAC address table can be affected.
•
Because disabling MAC address learning may result in broadcast storms, enable broadcast storm
suppression after you disable MAC address learning on a port.
