What is swNlbMulticastFdbEgressPorts?

This object defines the set of switch ports that traffic for a specific multicast MAC address in the NLB multicast forwarding database must be forwarded out of, supporting Microsoft NLB configured in multicast mode where a shared multicast MAC needs to reach several physical server ports. Administrators configure this so incoming traffic for the NLB cluster's multicast MAC gets replicated out to all the ports connecting to cluster member servers. For example, an admin might configure this object with a port list covering ports 2 and 4 so traffic addressed to the cluster's multicast MAC reaches both NLB nodes.
