- So I've been trying to complete my MCSA, I'm now on 412. Anyway, NLB (network load balancing). I'm struggling with how it works. Multicast: Each node in the cluster keeps it's own mac and IP address, whilst also using the cluster defined IP and Mac address. I'm struggling to understand what MAC address the switch is aware of.
- Apr 05, 2019 To configure the NLB cluster operation mode, use the following steps: In Server Manager, select Administrative tools and then select Network Load Balancing Manager. If NLB Manager does not already list the cluster, connect to the cluster. Right-click the cluster and select Cluster Properties.
- All of the members in the cluster. The NLB creates a fictitious MAC address and assigns it to each server in the NLB cluster. The NLB assigns each NLB server a different fictitious MAC address, based on the host ID of the member. This address appears in the Ethernet frame header. The MAC address is used in the Address Resolution Protocol (ARP) header, not the Ethernet header.

May 24, 2012 When running Microsoft Network Load Balancing (NLB) configured in unicast mode, the Network traffic is directed to only one of the nodes. In unicast mode, all the NICs assigned to a Microsoft NLB cluster share a common MAC address. This requires that all the network traffic on the switches be port-flooded to all the NLB nodes.
Cluster
contains the settings to specify details about a cluster, such as its interface, IP address, portrules, and so on.Note
To enable this Network Load Balancing setting, the NetworkLoadBalancingFullServer package must be enabled in the Windows image you are installing. To do this, use Windows System Image Manager to add the Microsoft-Windows-Foundation-Package to your answer file, and then configure the NetworkLoadBalancingFullServer package to enable it. For more information about adding and configuring packages, see the Windows Assessment and Deployment (Windows ADK) Technical Reference.

-->The MicrosoftNLB_ClusterSettingWMI class represents data that identifies the Network Load Balancing (NLB) cluster to which a node belongs.
The following syntax is simplified from MOF code and includes all inherited properties.
Syntax
Members
The MicrosoftNLB_ClusterSetting class has these types of members:
Methods
The MicrosoftNLB_ClusterSetting class has these methods.
Method | Description |
---|---|
AccessNLBRegParam | This method gets or sets instance-specific or global NLB registry parameters. |
LoadAllSettings | Propagates all current settings (cluster, node, and port rules) to the NLB driver. |
SetDefaults | Resets all of the properties of the MicrosoftNLB_ClusterSetting class to their default values. |
SetPassword | This method is no longer available. |
Properties
The MicrosoftNLB_ClusterSetting class has these properties.
AdapterGuid
Data type: string
Access type: Read-only
The GUID of the adapter to which NLB is bound.
BDAReverseHash
Data type: Boolean
Access type: Read-only
Indicates whether bi-directional affinity (BDA) will reverse hash on the cluster that this network adapter is a part of. For more information on BDA, please see online help.
BDATeamActive
Data type: Boolean
Access type: Read-only
Indicates whether BDA is enabled on the cluster that this network adapter is a part of.
BDATeamId
Data type: string
Access type: Read-only
The BDA team identifier of the cluster that this network adapter is a part of. The value of this property must be a GUID.
BDATeamMaster
Data type: Boolean
Access type: Read-only
Indicates whether the cluster that this network adapter is a part of is the BDA master cluster.
Microsoft Nlb Cluster Mac Address Search
Caption
Data type: string
Access type: Read-only
Qualifiers: MaxLen (64)
Not used.
This property inherits from CIM_Setting.
ClusterIPAddress
Data type: string
Access type: Read-only
Qualifiers: ModelCorrespondence ('CIM_Cluster.InterconnectAddress')
The cluster's primary IP address in standard dotted decimal notation ('xxx.xxx.xxx.xxx').

The media access control (MAC) address of the cluster.
ClusterName
Data type: string
Access type: Read-only
The full Internet name for the NLB cluster (for example, 'cluster.domain.com'). This name is used for the cluster as a whole and should be the same for all nodes in the cluster.

This property inherits from CIM_Setting.
IdentityHeartbeatEnabled
Data type: Boolean
Access type: Read-only
Qualifiers: DEPRECATED
This property is no longer in use.
IGMPSupport
Data type: Boolean
Access type: Read-only
Determines how multicast traffic is handled as follows.
FALSE
Default. NLB does not send IGMP join messages. Switches send all traffic (including multicast packets) to all switch ports.
TRUE
NLB sends IGMP join messages. Switches to send multicast traffic to specific ports rather than to all ports.
MulticastIPAddress
Data type: string
Access type: Read-only
The multicast IP address used to derive the cluster's MAC address if ClusterIPToMulticastIP is FALSE. A multicast IP group address should not interfere with other traffic or hinder any multicast applications that may be running on nodes that are part of the subnet on which the NLB cluster resides.
MulticastSupportEnabled
Data type: Boolean
Access type: Read-only
Indicates whether a multicast MAC address should be used for cluster operations. If this option is enabled, NLB converts the cluster MAC address belonging to the cluster adapter into a multicast address. It also ensures that the cluster's primary IP address resolves to this multicast address as part of the ARP protocol. At the same time, the adapter can now use its original, built-in MAC address, which, in unicast mode, was disabled.
Name
Data type: string https://adimriseg.tistory.com/19.
Access type: Read-only
Qualifiers: Key
The name of the node to which these settings apply. This is the name stored in the MicrosoftNLB_NodeName property.

Data type: Boolean
Access type: Read-only
Qualifiers: DEPRECATED
This property is no longer in use. To access a remote node's settings or to perform actions such as enabling or disabling a port rule, you must connect to each node individually using WMI. For an example, see Making Direct Connections.
SettingID
Data type: string
Access type: Read-only
Qualifiers: MaxLen (256)
Not used.
This property inherits from CIM_Setting.
UnicastInterHostCommSupportEnabled
Data type: Boolean
Access type: Read-only
This property enables inter-host communication in a unicast cluster.
Remarks
Enumerating the MicrosoftNLB_ClusterSetting class always returns one instance only. This instance represents the cluster settings for the provider node.
After changing any MicrosoftNLB_ClusterSetting properties, you must call LoadAllSettings on every node in the cluster to bring the new values into effect. Mac media key forwarder download. For more information, see LoadAllSettings.
The MicrosoftNLB_ClusterSetting class is derived from the CIM_Setting class.
