Descripción detallada

The Set-DhcpServerv4Failover cmdlet modifies the properties of an existing failover relationship.

If the failover mode of relation is load balance or is being changed to load balance , then the LoadBalancePercent, MaxClientLeadTime, StateSwitchInterval, AutoStateTransition, and SharedSecret parameters can be specified.

If the failover mode of relation is hot standby or is being changed to hot standby, then the ReservePercent, MaxClientLeadTime, StateSwitchInterval, AutoStateTransition, and SharedSecret parameters can be specified.

If the SharedSecret parameter value is Null, then enableauth will be set to False in the data structure. If the SharedSecret parameter is not Null, then enableauth will be set to True in the data structure.

If the SharedSecret parameter is specified, then confirmation will be sought from the user to transport the shared secret in the clear text on the network.

If you specify the Mode parameter to change the mode of the failover relationship, default confirmation will be sought.

Parámetros

-AsJob

-AutoStateTransition<Boolean>

Specifies the enabled state for automatic state transition from the COMMUNICATION INTERRUPTED state to the PARTNER DOWN state based on expiration of the timer, using the StateSwitchInterval parameter, while in the COMMUNICATION INTERRUPTED state.
Los valores aceptables para este parámetro son los siguientes: True or False. The default value is False.
Note: This parameter value is set to True, if the StateSwitchInterval parameter is specified.

-CimSession<CimSession[]>

Ejecuta el cmdlet en una sesión remota o en un equipo remoto. Escriba un nombre de equipo o un objeto de sesión, como la salida de un cmdlet New-CimSession o Get-CimSession. El valor predeterminado es la sesión actual en el equipo local.

-ComputerName<String>

Specifies the DNS name, or IPv4 or IPv6 address, of the target computer running the Dynamic Host Configuration Protocol (DHCP) server service.

-Force

Specifies, if the SharedSecret parameter is specified, that user confirmation is required since the SharedSecret parameter value may be transferred in plain text transport in the case of remote management. Specifying this parameter turns off the user confirmation.

-LoadBalancePercent<UInt32>

Specifies the percentage of DHCP client requests which should be served by the local DHCP server service or the DHCP server service running on the computer specified in the ComputerName parameter. The remaining DHCP client requests would be served by the partner DHCP server service.

-MaxClientLeadTime<TimeSpan>

Specifies the maximum client lead time for the failover relationship.

-Mode<String>

Specifies a mode for the failover relationship. Los valores aceptables para este parámetro son los siguientes:

-- HotStandby. Changes the mode to hot standby.
-- LoadBalance. Changes the mode to load balance.

-Name<String>

Specifies the name of failover relationship for which the properties are modified.

-PartnerDown

Changes the state of the DHCP server service from COMMUNICATION INTERRUPTED to PARTNER DOWN.

-PassThru

Devuelve un objeto que representa el elemento con el que está trabajando. De forma predeterminada, este cmdlet no genera ningún resultado.

-ReservePercent<UInt32>

Specifies the percentage of the free IPv4 address pool for the scope which should be reserved on the standby DHCP server service.
In the case of a failover, the IPv4 addresses from this reserved pool on the standby DHCP server service will be leased to new DHCP clients.

-SharedSecret<String>

Specifies the shared secret to be used for message authentication. To turn off message authentication, set this parameter value to Null.

-StateSwitchInterval<TimeSpan>

Specifies the time interval for which the DHCP server service should continue to operate in the COMMUNICATION INTERRUPTED state before transitioning to the PARTNER DOWN state.

-ThrottleLimit<Int32>

Especifica el número máximo de operaciones simultáneas que se pueden establecer para ejecutar el cmdlet. Si se omite este parámetro o es especifica un valor de 0, Windows PowerShell ® calcula un límite óptimo para el cmdlet en función del número de cmdlets de CIM que se estén ejecutando en el equipo. El límite solo se aplica al cmdlet actual, no a la sesión ni al equipo.

-Confirm

Solicita confirmación antes de ejecutar el cmdlet.

-WhatIf

Muestra lo que sucedería si se ejecutara el cmdlet. El cmdlet no se ejecuta.

<CommonParameters>

Este cmdlet admite los siguientes parámetros comunes: -Verbose, -Debug, -ErrorAction, -ErrorVariable, -OutBuffer y -OutVariable. Para obtener más información, consulte about_CommonParameters (https://go.microsoft.com/fwlink/p/?LinkID=113216).

Entradas

El tipo de entrada es el tipo de los objetos que se pueden canalizar al cmdlet.

• Microsoft.Management.Infrastructure.CimInstance#root/Microsoft/Windows/DHCP/DhcpServerv4Failover

  El objeto Microsoft.Management.Infrastructure.CimInstance es una clase contenedora que muestra objetos de Instrumental de administración de Windows (WMI). La ruta de acceso después del signo de número (#) proporciona el espacio de nombres y el nombre de clase del objeto WMI subyacente.

Ejemplos

EXAMPLE 1

This example modifies the parameters of the load balance failover relationship named SFO-SIN-Failover on the computer named dhcpserver.contoso.com as follows: 70% of the client requests will be served by the DHCP server service running on the computer named dhcpserver.contoso.com and 30% of the client requests will be served by the DHCP server service running on the computer named dhcpserver2.contoso.com. The maximum client lead time for the failover relationship is set to 2 hours. The automatic state transition from the COMMUNICATION INTERRUPTED state to the PARTNER DOWN state is enabled and the timer for automatic state transition is set to 2 hours.

PS C:\> Set-DhcpServerv4Failover -ComputerName dhcpserver.contoso.com -Name SFO-SIN-Failover -LoadBalancePercent 70 -MaxClientLeadTime 2:00:00 -AutoStateTransition True -StateSwitchInterval 2:00:00

EXAMPLE 2

This example modifies the parameters of the hot standby failover relationship named SFO-SIN-Failover on computer named dhcpserver.contoso.com as follows: 10% of the free IP addresses in the scopes will be reserved for the standby DHCP server service. The maximum client lead time for the failover relationship is set to 2 hours. The automatic state transition from the COMMUNICATION INTERRUPTED state to the PARTNER DOWN state is enabled and the timer for automatic state transition is set to 2 hours.

PS C:\> Set-DhcpServerv4Failover -ComputerName dhcpserver.contoso.com -Name SFO-SIN-Failover -ReservePercent 10 -MaxClientLeadTime 2:00:00 -AutoStateTransition True -StateSwitchInterval 2:00:00

EXAMPLE 3

This example changes the mode of the failover relationship SFO-SIN-Failover to LoadBalance. The computer named dhcpserver.contoso.com serves 60 percent of the clients.

PS C:\> Set-DhcpServerv4Failover -Name SFO-SIN-Failover -ComputerName dhcpserver.contoso.com -Mode LoadBalance -LoadBalancePercent 60
