Page 335: Incorrect Information About Unexpected Manner Of Network Traffic
On page 335, in the top paragraph, change:
"Network traffic might be causing a large amount of collisions or might not consistently arrive at its intended destination. In this situation, the switch and the unicast network address are conflicting with each other. If you're using a switch to connect the hosts in your cluster configuration, NLB must be set to use multicast mode. If you cannot change the mode to unicast, you must connect your cluster hosts in some other way, perhaps with a hub or coaxial cable. Otherwise, you'll have to switch to multicast mode using the Cluster Parameters tab of the network load balancing properties dialog box."
"Network traffic might be causing a large amount of collisions or might not consistently arrive at its intended destination when connections are made across a switch to which the NLB virtual adapters are connected. This problem occurs because a large number of unknown unicast and multicast packets are being blocked on the port(s) of the switch. By default, NLB masks the source media access control (MAC) address on outbound packets, preventing switches from learning and forcing them to broadcast packets for unknown addresses to all ports.
"To resolve this issue, you can replace the switch with a hub, disable port blocking, add a static address to the MAC address table on the switch that maps to the virtual MAC address used by the NLB cluster, or modify the registry of each NLB cluster host to disable masking of the MAC address."
