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

Syntax

Parameter Set: __AllParameterSets
Export-DhcpServer [-File] <String> [-CimSession <CimSession> ] [-ComputerName <String> ] [-Force] [-Leases] [-Prefix <IPAddress[]> ] [-ScopeId <IPAddress[]> ] [ <CommonParameters>]




Detailed Description

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

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

If neither ScopeId nor Prefix is specified, then the entire DHCP server service configuration including all scopes, v4 and v6 and optionally the lease data, is exported.

If Leases parameter is specified, then the lease data is also exported in addition to configuration data.

Parameters

Examples

EXAMPLE 1

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.


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

EXAMPLE 2

This example exports the specified scopes 10.10.10.0 and 20.20.20.0 present on the DHCP server service to the specified export file in XML file format. The DHCPv4 server level configuration will also be exported to the specified file.


PS C:\> Export-DhcpServer -ComputerName dhcpserver.contoso.com -File C:\exportdir\dhcpexport.xml -ScopeId 10.10.10.0,20.20.20.0

EXAMPLE 3

This example exports the specified scopes 10.10.10.0 and 20.20.20.0 present on the DHCP server service to the specified export file in XML file format, including the leases present in the specified scopes. The DHCPv4 server level configuration will also be exported to the specified file.


PS C:\> Export-DhcpServer -ComputerName dhcpserver.contoso.com -File C:\exportdir\dhcpexport.xml -ScopeId 10.10.10.0,20.20.20.0 -Leases

EXAMPLE 4

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 will also be exported to the specified file.


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

EXAMPLE 5

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, including the leases present in the specified scopes. The DHCP server level configuration will also be exported to the specified file.


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

EXAMPLE 6

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 containing 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


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