CN4093 Application Guide for N/OS 8.3
 You must configure the ARP only in the Layer 2/Layer 3 node or the router node
but not in the Layer 2-only node. Lenovo N/OS cannot validate if the node is
Layer 2-only.
 The packet is always forwarded to all the ports as specified in the Multicast
MAC address configuration. If VLAN membership changes for the ports, you
must update this static multicast MAC entry. If not, the ports, whose
membership has changed, will report discards.
 ACLs take precedence over static multicast ARP. If an ACL is configured to
match and permit ingress of unicast traffic, the traffic will be forwarded based
on the ACL rule, and the static multicast ARP will be ignored.
