Set-NlbClusterPortRuleNodeWeight
Sets the load weight of a port rule for a specific NLB node.
Set-NlbClusterPortRuleNodeWeight [-Port] <UInt32> -InterfaceName <string> -IP <IPAddress> [-HostName <string>] [-Equal] [-LoadWeight <System.Nullable`1[[System.Int32>] [<CommonParameters>]
Set-NlbClusterPortRuleNodeWeight -InputObject <PortRule[]> [-Equal] [-LoadWeight <System.Nullable`1[[System.Int32>] [<CommonParameters>]
The Set-NlbClusterPortRuleNodeWeight cmdlet sets the load weight of a port rule for a specific NLB node. The load weight applies only for the Multiple hosts filtering mode. When using the Multiple hosts filtering mode, the load weight specifies the relative amount of load-balanced network traffic that this node should handle for the associated port rule. Allowed values range from 0 (zero) to 100. To prevent a host from handling any network traffic, set the load weight to 0 (zero). The actual fraction of traffic handled by each node is computed as the local load weight divided by the sum of all load weights across the cluster. You can specify different load weights for each node in the cluster using the LoadWeight parameter. Or, you can specify that all nodes distribute the network load equally by using the Equal parameter instead of the LoadWeight parameter.
This operation changes the configuration on all cluster nodes. As a result, the NLB cluster will have to restart the convergence process on all nodes to guarantee that configuration changes have been applied on all nodes and that a consistent state is reached. Any additional operations on the NLB cluster should not be initiated until all cluster nodes have completed the convergence process and are back to the converged state. To check the state of all cluster nodes, use the Get-NlbClusterNode cmdlet. If a configuration change results in the cluster nodes remaining in perpetual convergence, refer to the event log to resolve the configuration inconsistency between the cluster nodes.
Sets the port rule weight to Equal on the cluster node. This specifies that all nodes distribute the network load equally. This parameter is only applicable when the port rule filtering mode is multiple host.
