Updated: October 17, 2013

Applies To: Windows 8.1, Windows PowerShell 4.0, Windows Server 2012 R2

Set-NlbClusterPortRuleNodeHandlingPriority

Sets the host priority of a port rule for a specific Network Load Balancing (NLB) node.

Syntax

Parameter Set: NonPipeline
Set-NlbClusterPortRuleNodeHandlingPriority [-Port] <UInt32> -HandlingPriority <Int32> -InterfaceName <String> -IP <IPAddress> [-HostName <String> ] [ <CommonParameters>]

Parameter Set: Pipeline
Set-NlbClusterPortRuleNodeHandlingPriority -HandlingPriority <Int32> -InputObject <PortRule[]> [ <CommonParameters>]




Detailed Description

The Set-NlbClusterPortRuleNodeHandlingPriority cmdlet sets the host priority of a port rule for a specific Network Load Balancing (NLB) node. The host priority specifies a unique identifier (ID) for each node. The node with the lowest numerical priority among the current members of the cluster handles all of the network traffic on the cluster that is not covered by a port rule. You can override these priorities or provide load balancing for specific ranges of ports by specifying rules. If a new node joins the cluster and its priority conflicts with another node in the cluster, then the node is not accepted as part of the cluster. The rest of the cluster will continue to handle the traffic.

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.

Parameters

Examples

EXAMPLE 1

This example changes the handling priority of the given port rule for the node named node1 to 3. This is applicable for port rules with Single mode.


PS C:\> Get-NlbClusterNode –NodeName node1 | Get-NlbClusterPortRule | Set-NlbClusterPortRuleNodeHandlingPriority -HandlingPriority 3
IPAddress State     Start     End       Protocol  Mode      Affinity  Timeout 
--------- -----     -----     ---       --------  ----      --------  ------- 
All       Enabled   0         65535     Both      Single 

EXAMPLE 2

This example changes the handling priority of the given port rule for the node named node1 to 4. This is applicable for port rules with Single mode.


PS C:\> Set-NlbClusterPortRuleNodeHandlingPriority -HostName node1 -Interface vlan-3 -IP 255.255.255.255 -Port 80 -HandlingPriority 4
IPAddress State     Start     End       Protocol  Mode      Affinity  Timeout 
--------- -----     -----     ---       --------  ----      --------  ------- 
All       Enabled   0         65535     Both      Single
