How can I tell if my switch is compatible with Microsoft load balancing?
MS article says
If Network Load Balancing clients are accessing a cluster through a router when the cluster has been configured to operate in multicast mode, be sure that the router meets the following requirements:
â¢ Accepts an ARP reply that has one MAC address in the payload of the ARP structure but appears to arrive from a station with another MAC address, as identified by the Ethernet header.
â¢ In multicast mode, accepts an ARP reply that has a multicast MAC address in the payload of the ARP structure.
This allows the router to map the cluster's primary IP address and other multihomed addresses to the corresponding MAC address. If your router does not meet these requirements, you can also create a static ARP entry in the router. Cisco routers require a static ARP entry because they do not support the resolution of unicast IP addresses to multicast MAC addresses.
In multicast mode, the IGMP multicast check box enables Internet Group Management Protocol (IGMP) support for limiting switch flooding by limiting traffic to "Network Load Balancing ports" only. That is, enabling IGMP support ensures that traffic intended for a Network Load Balancing cluster passes through only those ports serving the cluster hosts and not all switch ports.
