Import-DhcpServer

Imports the Dynamic Host Configuration Protocol (DHCP) server service configuration, and optionally lease data, from the specified file.

Sintaxis

Parameter Set: Default
Import-DhcpServer [-File] <String> [-BackupPath] <String> [-CimSession <CimSession> ] [-ComputerName <String> ] [-Force] [-Leases] [-Prefix <IPAddress[]> ] [-ScopeId <IPAddress[]> ] [-ScopeOverwrite] [-ServerConfigOnly] [ <CommonParameters>]




Descripción detallada

The Import-DhcpServer cmdlet imports the Dynamic Host Configuration Protocol (DHCP) server service configuration, and optionally lease data, from the specified file. This cmdlet is only supported for the DHCP server services running on Windows Server® 2012.

If either the ScopeId or the Prefix parameter, or the ScopeId and Prefix parameters are specified, then only the specified scopes or prefixes will be imported.

If neither the ScopeId nor the Prefix parameter is specified, then all of the configurations contained in the file, and optionally any lease data, will be imported.

If the Leases parameter is specified, then the lease data in the specified file is imported in addition to configuration data.

If the ScopeOverWrite parameter is specified and the scope being imported exists on the destination server, then the scope on the target DHCP server service will be overwritten. If this parameter is not specified and the scope being imported exists on the destination DHCP server service, then a warning message is displayed and the import will proceed to process the next scope being imported.

If the ServerConfigOnly parameter is specified, then only the server level configuration will be imported on the destination DHCP server service. If the file specified contains any scope information, then the same information will not be imported on the destination DHCP server service.

Ejemplos

EXAMPLE 1

This example imports the configuration data in the specified file onto the DHCP server service running one the computer named dhcpserver.contoso.com. The file can contain DHCPv4 as well as DHCPv6 configuration data.


PS C:\> Import-DhcpServer -ComputerName dhcpserver.contoso.com -File C:\exports\dhcpexport.xml -BackupPath C:\dhcpbackup\

EXAMPLE 2

This example imports the configuration and lease data in the specified file onto the DHCP server service running on the computer named dhcpserver.contoso.com. The file can contain DHCPv4 as well as DHCPv6 configuration data.


PS C:\> Import-DhcpServer -ComputerName dhcpserver.contoso.com -File C:\exports\dhcpexport.xml -BackupPath C:\dhcpbackup\ -Leases

EXAMPLE 3

This example imports the configuration data for scopes 10.10.10.0 and 20.20.20.0 from the specified file onto the DHCP server service running on the computer named dhcpserver.contoso.com. If the export file contains scopes besides 10.10.10.0 and 20.20.20.0, then those scopes are ignored. The DHCPv4 server level configuration data, if present in the export file, is also imported onto the DHCP server service.


PS C:\> Import-DhcpServer -ComputerName dhcpserver.contoso.com -File C:\exports\dhcpexport.xml -BackupPath C:\dhcpbackup\ -ScopeId 10.10.10.0,20.20.20.0

If the export file contains scopes besides 10.10.10.0 and 20.20.20.0, then those scopes are ignored. The DHCPv4 server level configuration data, if present in the export file, is also imported onto the DHCP server service.

If the export file contains scopes besides 10.10.10.0 and 20.20.20.0, then those scopes are ignored. The DHCPv4 server level configuration data, if present in the export file, is also imported onto the server. If the scopes 10.10.10.0 and 20.20.20.0 are already present on the DHCP server service running one the computer named dhcpserver.contoso.com, then the scopes are deleted and recreated from the data in the export file.

EXAMPLE 10

This example imports a list of scopes specified in file named ScopeList.txt to the DHCP server service running on the computer named dhcpserver.contoso.com.
The file named ScopeList.txt should contain the following format:
ScopeID
10.10.10.0
20.20.20.0
30.30.30.0


 

The Import-Csv cmdlet gets the list of scopes to import and returns it in the variable named $scopeIdList.


PS C:\> $scopeIdList = Import-Csv –Path .\ScopeList.txt

 

This cmdlet imports the scopes using the variable named $scopeIdList as input for the ScopeId parameter.


PS C:\> Import-DhcpServer -ComputerName dhcpserver.contoso.com -File C:\exportdir\dhcpexport.xml -Leases -ScopeId $scopeIdList.ScopeId -BackupPath C:\dhcpbackup\
