| - MAC aging with specified aging interval enable/disable |
| - MAC flush of learned MACs on interface down, BD deletion, or by user |

| - User added MACs not subject to aging but can be overwritten by MAC learn |
| - Unicast forwarding enable/disable |
| - Unknown unicast flooding enable/disable |
| - Multicast/broadcast flooding enable/disable |
| - ARP-termination to avoid flooding of ARP requests |
| - Enable/disable unicast of ARP requests instead of flooding |
