arp

We're running a Microsoft NLB cluster in multicast mode as a loadbalancer. Using our old Cisco IOS switches we propagate access to the cluster to our branches using a static ARP entry in the core router:

arp 10.20.1.226 03bf.0a14.01e2 ARPA

But how does one solve this using non-IOS based Cisco hardware such as the SG300 series? Adding a static ARP entry results in an error message telling the user that the hardware address needs to be a valid unicast MAC address.
