Mac-Address Max-Mac-Count - HP A5830 Series Command Reference Manual

Follow these guidelines when configuring 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 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.
When MAC address learning is disabled, the learned MAC addresses remain valid until they age out.
