By default, AKS sets *AllocatedOutboundPorts* on its load balancer to `0`, which enables [automatic outbound port assignment based on backend pool size][azure-lb-outbound-preallocatedports] when creating a cluster. For example, if a cluster has 50 or fewer nodes, 1024 ports are allocated to each node. As the number of nodes in the cluster increases, fewer ports are available per node. To show the *AllocatedOutboundPorts* value for the AKS cluster load balancer, use `az network lb outbound-rule list`.
