Description
The Get-NlbClusterDriverInfo cmdlet retrieves information about the Network Load Balancing (NLB) driver on the local machine. This includes information about IP addresses, ports, convergence history, connections, extended affinity status, and protocols.
Examples
EXAMPLE 1
PS C:\>Get-NlbClusterDriverInfo
FullyQualifiedDomainName : cluster1.contoso.com
ParametersVersion : 6
EffectiveNlbVersion : 513
HostId : 2
ClusterName : cluster1
ClusterIPAddress : 2001:4898:e8:3018:bd82:dde1:6615:7b0
ClusterMacAddress : 02-BF-FB-7E-A2-D1
AliveMsgPeriod : 1000
MaxConnectionDescriptors : 262144
IcmpFilteringEnabled : False
InitialHostState : Started
CurrentHostState : Started
PersistedHostStates : True
This example gets information about the NLB driver configuration.
EXAMPLE 2
PS C:\>Get-NlbClusterDriverInfo -ConvergenceHistory
Time FromState ToState
---- --------- -------
11/5/2008 10:55:27 PM StablePhase2 Converged
11/5/2008 10:55:26 PM ConvergingPhase2 StablePhase2
11/5/2008 10:55:26 PM StablePhase1 ConvergingPhase2
11/5/2008 10:55:20 PM ConvergingPhase1 StablePhase1
11/5/2008 10:55:17 PM Unknown ConvergingPhase1
This example gets the history of convergence for the local node.
EXAMPLE 3
PS C:\>Get-NlbClusterDriverInfo -Filter TCP -ServerIP 2.53.4.222 -ServerPort 5001 -ClientIP 2.53.4.5 -ClientPort 5001
Result
------
ACCEPT_UNCONDITIONAL_OWNERSHIP
This example declares whether traffic in the given pattern will be accepted on the local node or not.
EXAMPLE 4
PS C:\>Get-NlbClusterDriverInfo -ExtendedAffinityList
IPAddress References VirtualIPAddress StartPort
--------- ---------- ---------------- ---------
2.53.4.5 0 All 0
2.53.4.6 0 All 0
2.53.4.7 1 All 0
This example will enumerate the client IP addresses that are on the extended affinity list on this cluster node. This applies to port rules that have extended affinity timeout enabled. The cmdlet also displays the number of active connections for each client.
EXAMPLE 5
PS C:\>Get-NlbClusterDriverInfo -ExtendedAffinityExceptionList
IPAddress HostId VirtualIPAddress StartPort
--------- ------ ---------------- ---------
2.53.4.6 2 All 0
This example will enumerate the client IP addresses that are on the extended affinity exception list. This applies to port rules that have extended affinity timeout enabled. Traffic from clients on this list will be picked up by another cluster node that has the host ID listed.
EXAMPLE 6
PS C:\>Get-NlbClusterDriverInfo -OpenConnections
SourceIPAddress SourcePort DestinationIPAddres DestinationPorts
--------------- ---------- ------------------- ---------------
2.53.4.5 64945 2.53.4.222 5001
2.53.4.15 64854 2.53.4.222 80
This example enumerates all open connections on this cluster node. This is useful to run when the draining operation takes a long time and the administrator wants to know which connections are on the node.
