Usage guidelines
Dynamic ARP entry check disables a device from supporting dynamic ARP entries with multicast
MAC addresses. The device cannot learn dynamic ARP entries containing multicast MAC addresses.
You cannot manually add static ARP entries that contain multicast MAC addresses.
When dynamic ARP entry check is disabled, ARP entries containing multicast MAC addresses are
supported. The device can learn dynamic ARP entries containing multicast MAC addresses obtained
from the ARP packets sourced from a unicast MAC address. You can also manually add static ARP
entries containing multicast MAC addresses.
