R211x-HP Flexfabric 11900 Layer 2 - LAN Switching Command Reference

74
• Because disabling MAC address learning can result in broadcast storms, enable broadcast storm
suppression after you disable MAC address learning on an interface. For more information about
broadcast storm suppression, see Layer 2—LAN Switching Configuration Guide.
• With MAC address learning enabled globally, you can disable MAC address learning for the
specific interface or VLAN.
This command does not take effect in a TRILL network, in a VPLS VSI, or for an S-channel in an EVB. For
information about TRILL, see TRILL Configuration Guide. For information about VSI, see MPLS
Configuration Guide. For information about S-channel and EVB, see EVB Configuration Guide.
When MAC address learning is disabled, the learned MAC addresses remain valid until they age out.
