This configures whether hardware-based multicast traffic hashing is enabled on the IOM uplinks for chassis discovered under this policy, affecting how multicast streams such as those used by KVM or vMedia sessions get load-balanced across the aggregated links. An admin enables this on chassis carrying heavy multicast workloads to prevent all multicast traffic from hashing onto a single physical uplink and creating a bottleneck. A typical value is simply 'enabled' or 'disabled'.
