Usage guidelines
The dynamic ARP entry check function controls whether the device supports dynamic ARP entries with
multicast MAC addresses.
When dynamic ARP entry check is enabled, the device cannot learn dynamic ARP entries containing
multicast MAC addresses, and you cannot manually add static ARP entries containing multicast MAC
addresses.
When dynamic ARP entry check is disabled, 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.
