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 this function 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.
