What are defaults for 2016 latency settings?

Q. What are the defaults for Windows Server 2016 Failover Clusters related to latency?

A. In Windows Server 2012 R2 some of the latency related settings of a cluster such as SameSubnetThreshold and CrossSubnetThreshold were modified once Hyper-V VMs were present. In Windows Server 2016 the cluster defaults have changed as follows (to essentially match the values previously used only when Hyper-V was present):

Property Win2016 Default Description
SameSubnetDelay  1 Frequency heartbeats (HB) sent
SameSubnetThreshold  10 Missed HB before interface considered down
CrossSubnetDelay  1 Frequency HB sent to nodes on dissimilar subnets
CrossSubnetThreshold  20 Missed HB before interface considered down to nodes on dissimilar subnets
CrossSiteDelay 1 Frequency HB sent to nodes on dissimilar sites
CrossSiteThreshold 20 Missed HB before interface considered down to nodes on dissimilar sites
