Description

The Export-DhcpServer cmdlet exports the Dynamic Host Configuration Protocol (DHCP) server service configuration, and optionally lease data, to the specified file.

If you specify the ScopeId or Prefix parameter,only the specified scopes or prefixes and all server level settings are exported.

If you specify neither ScopeId or Prefix, the DHCP server service configuration including all scopes, v4 and v6 and optionally the lease data, is exported.

If you specify the Leases parameter, the lease data is also exported in addition to configuration data.

Examples

Example 1: Export all DHCP configurations

PS C:\> Export-DhcpServer -ComputerName "dhcpserver.contoso.com" -File "C:\exportdir\dhcpexport.xml"

This example exports all of the DHCP server, DHCPv4 and DHCPv6, configurations including scopes present on the DHCP server service to the specified export file in XML file format.

Example 2: Export the specified scopes

PS C:\> Export-DhcpServer -ComputerName "dhcpserver.contoso.com" -File "C:\exportdir\dhcpexport.xml" -ScopeId 10.10.10.0,10.20.20.0

This example exports the scopes 10.10.10.0 and 10.20.20.0 present on the DHCP server service to the specified export file in XML file format. The DHCPv4 server level configuration is also exported to the specified file.

Example 3: Export specified scopes and their leases

PS C:\> Export-DhcpServer -ComputerName "dhcpserver.contoso.com" -File "C:\exportdir\dhcpexport.xml" -ScopeId 10.10.10.0,10.20.20.0 -Leases

This example exports the scopes 10.10.10.0 and 10.20.20.0 present on the DHCP server service to the specified export file in XML file format. This includes the leases present in the specified scopes. The DHCPv4 server level configuration will also be exported to the specified file.

Example 4: Export the specified scopes and DHCPv6 server level configuration

PS C:\> Export-DhcpServer -ComputerName "dhcpserver.contoso.com" -File "C:\exportdir\dhcpexport.xml" -Prefix 2001:4898:7020:1020::,2001:4898:7020:1030::

This example exports the specified scopes 2001:4898:7020:1020:: and 2001:4898:7020:1030:: present on the DHCP server service to the specified export file in XML file format. The DHCPv6 server level configuration is also exported to the specified file.

Example 5: Export the specified scopes, their leases, and DHCPv6 server level configuration

PS C:\> Export-DhcpServer -ComputerName "dhcpserver.contoso.com" -File "C:\exportdir\dhcpexport.xml" -Prefix 2001:4898:7020:1020::,2001:4898:7020:1030:: -Leases

This example exports the specified scopes 2001:4898:7020:1020:: and 2001:4898:7020:1030:: present on the DHCP server service to the specified export file in XML file format. This includes the leases present in the specified scopes. The DHCP server level configuration is also exported to the specified file.

Example 6: Export scopes specified in a file

PS C:\> Import-Csv -Path "ScopeList.txt" | Export-DhcpServer -ComputerName "dhcpserver.contoso.com" -File "C:\exportdir\dhcpexport.xml" -Leases

This example exports a list of scopes specified in file named ScopeList.txt to the specified export file in XML file format. The Import-Csv cmdlet returns the objects that contain the scope IDs output and pipes the objects into this cmdlet, which exports the specified scopes.

The file named ScopeList.txt should contain the following format:

ScopeId

10.10.10.0

20.20.20.0

30.30.30.0
