Because the nature of MS load balancing is to use the sampel virtual MAC address for all the servers in the load balance cluster, the switch floods packets to the virtual MAC address to ALL ports of the switch. We have a 5505 with several dozen unix hosts on it along with 5 MS servers that are in load balancing mode. Since the traffice destined to the MS servers is flooded to all the ports, it is affecting some of the unix hosts.
Has anyone run into this scenario? Is the only way to make this more stable is to move the 5 MS load balanced servers off onto a new switch with a new subnet? (I don't want to have multiple vlans on the same 5505).
