Enable MAC address move notifications

The outgoing interface for a MAC address entry learned on interface A is changed to interface B
when the following conditions exist:
•
Interface B receives a packet with the MAC address as the source MAC address.
•
Interface B belongs to the same VLAN as interface A.
In this case, the MAC address is moved from interface A to interface B, and a MAC address move
occurs.
If a MAC address is continuously moved between the two interfaces, Layer 2 loops might occur.. To
detect and locate loops, you can view the MAC address move information.
When the system detects that a MAC address frequently moves from an interface, you can configure
MAC address move suppression on the interface to bring it down. The interface can automatically
come up after waiting for the specified suppression interval. Or, you can manually bring up the
interface. To make MAC address move suppression take effect, you must use this feature together
with ARP fast update. For more information about ARP fast update, see
for MAC address
To display the MAC address move records after the device is started, use the display mac-address
mac-move command.
