Mac-Address Max-Mac-Count - HP 6125G Command Reference Manual

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.
