Add-NlbClusterPortRule

Adds a new port rule to a Network Load Balancing (NLB) cluster.

Syntax

Parameter Set: NonPipeline
Add-NlbClusterPortRule [-StartPort] <Int32> [-EndPort] <Int32> -InterfaceName <String> [-Affinity <PortRuleAffinity> {Network | None | Single} ] [-HostName <String> ] [-IP <IPAddress> ] [-Mode <PortRuleFilteringMode> {Disabled | Multiple | Single} ] [-Protocol <PortRuleProtocol> {Both | Tcp | Udp} ] [-Timeout <UInt32> ] [ <CommonParameters>]

Parameter Set: Pipeline
Add-NlbClusterPortRule [-StartPort] <Int32> [-EndPort] <Int32> -InputObject <Cluster[]> [-Affinity <PortRuleAffinity> {Network | None | Single} ] [-IP <IPAddress> ] [-Mode <PortRuleFilteringMode> {Disabled | Multiple | Single} ] [-Protocol <PortRuleProtocol> {Both | Tcp | Udp} ] [-Timeout <UInt32> ] [ <CommonParameters>]




Detailed Description

The Add-NlbClusterPortRule cmdlet adds a new port rule to a Network Load Balancing (NLB) cluster. Port rules control how an NLB cluster functions. To maximize the control of various types of TCP/IP traffic, you can set up port rules to control how each port's cluster-network traffic is handled. The method by which a port's network traffic is handled is called its filtering mode. There are three possible filtering modes: Multiple hosts, Single host, and Disabled. A filtering mode can also apply to a numerical range of ports. You do this by defining a port rule with a set of configuration parameters that define the filtering mode. In addition, you can select one of three options for client affinity: None, Single, or Network. Single and Network are used to ensure that all network traffic from a particular client is directed to the same cluster host. To allow NLB to properly handle IP fragments, you should avoid using None when you select UDP or Both for your protocol setting.

This cmdlet 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.

Examples

EXAMPLE 1

This example adds a new port rule to the local cluster. The new port rule covers port 443 only, and uses the default settings for the rest of the port rule parameters.


PS C:\> Get-NlbCluster | Add-NlbClusterPortRule -StartPort 443 -EndPort 443
IPAddress State     Start     End       Protocol  Mode      Affinity  Timeout 
--------- -----     -----     ---       --------  ----      --------  ------- 
All       Enabled   443       443       Both      Multiple  Single    0 

EXAMPLE 2

This example adds a new port rule to the local cluster. The new port rule covers port 80 only and has no affinity, and uses the default settings for the rest of the port rule parameters.


PS C:\> Get-NlbCluster | Add-NlbClusterPortRule -StartPort 80 -EndPort 80 -Affinity None
IPAddress State     Start     End       Protocol  Mode      Affinity  Timeout 
--------- -----     -----     ---       --------  ----      --------  ------- 
All       Enabled   80        80        Both      Multiple  None      0
