Description

The Remove-IpamSubnet cmdlet removes a given subnet from IP Address Management (IPAM). By default, the cmdlet returns an error if there are ranges associated with the subnet. You can use the DeleteAssociatedRanges parameter to delete the associated ranges. You can specify the DeleteAssociatedAddresses parameter to delete the associated IP Addresses.

Examples

Example 1 Remove a non-virtualized subnet with a mapped range

PS C:\> Remove-IpamSubnet -NetworkId 10.12.0.0/16 -NetworkType NonVirtualized

Confirm

Deleting the non-virtualized subnet Contoso_2 with network 10.12.0.0/16.

[Y] Yes  [N] No  [S] Suspend  [?] Help (default is "Y"): y

Remove-IpamSubnet : There are ranges associated with this subnet.

AM_Subnet) [Remove-IpamSubnet], CimException

+ FullyQualifiedErrorId : WIN32 8,Remove-IpamSubnet

This command removes a NonVirtualized subnet with a mapped range. An error occurs because a subnet cannot be deleted if there are ranges mapped to it

Example 2: Remove a non-virtualized subnet

PS C:\> Remove-IpamSubnet -NetworkId 10.12.0.0/16 -NetworkType NonVirtualized -DeleteAssociatedRanges

Confirm

Deleting the non-virtualized subnet Contoso_2 with network 10.12.0.0/16. Ranges mapped to this subnet will also be

deleted.

[Y] Yes  [N] No  [S] Suspend  [?] Help (default is "Y"):Y

This command removes a NonVirtualized subnet along with any ranges that are mapped to it. The cmdlet moves the mapped IP addresses to unmapped address space.

Example 3: Remove a non-virtualized subnet

PS C:\> Remove-IpamSubnet -NetworkId 10.12.0.0/16 -NetworkType NonVirtualized -DeleteAssociatedRanges -DeleteAssociatedAddresses

Confirm

Deleting the non-virtualized subnet Contoso_2 with network 10.12.0.0/16. Ranges mapped to this subnet and IP Addresses

associated via Ranges with this Subnet will also be deleted.

[Y] Yes  [N] No  [S] Suspend  [?] Help (default is "Y"):Y

This command removes a NonVirtualized subnet along with ranges that map to it. Also remove any IP addresses that map to this subnet via the ranges that map to this subnet.

Example 4: Remove a subnet for a provider network type

PS C:\> Remove-IpamSubnet -NetworkId 10.13.0.0/16 -NetworkType Provider -AddressSpace Default -DeleteAssociatedRanges

Confirm

Deleting the fabric subnet Contoso_3 with network 10.13.0.0/16. Ranges mapped to this subnet will also be deleted.

[Y] Yes  [N] No  [S] Suspend  [?] Help (default is "Y"):Y

This command removes a subnet for a provider network type from the default address space.

Example 5: Remove a subnet for a customer network type

PS C:\> Remove-IpamSubnet -NetworkId 10.11.8.0/24 -NetworkType Customer -AddressSpace Contoso -DeleteAssociatedRanges

Confirm

Deleting the virtual subnet Contoso_1 with network 10.11.8.0/24. Ranges mapped to this subnet will also be deleted.

[Y] Yes  [N] No  [S] Suspend  [?] Help (default is "Y"):Y

This command removes a subnet for a customer network type from the customer address space named Contoso.

Parameters

-AddressSpace

Specifies an array of names of address spaces. If you not specify an address space, the cmdlet removes all address spaces configured in IPAM.

Type:String[]
Position:Named
Default value:None
Required:False
Accept pipeline input:True
Accept wildcard characters:False

-AsJob

Runs the cmdlet as a background job. Use this parameter to run commands that take a long time to complete.

The cmdlet immediately returns an object that represents the job and then displays the command prompt. You can continue to work in the session while the job completes. To manage the job, use the *-Job cmdlets. To get the job results, use the Receive-Job cmdlet.

For more information about Windows PowerShell background jobs, see about_Jobs.

Type:SwitchParameter
Position:Named
Default value:None
Required:False
Accept pipeline input:False
Accept wildcard characters:False

-CimSession

Runs the cmdlet in a remote session or on a remote computer. Enter a computer name or a session object, such as the output of a New-CimSession or Get-CimSession cmdlet. The default is the current session on the local computer.

Type:CimSession[]
Aliases:Session
Position:Named
Default value:None
Required:False
Accept pipeline input:False
Accept wildcard characters:False

-Confirm

Prompts you for confirmation before running the cmdlet.

Type:SwitchParameter
Aliases:cf
Position:Named
Default value:False
Required:False
Accept pipeline input:False
Accept wildcard characters:False

-DeleteAssociatedAddresses

Indicates that the cmdlet deletes the addresses associated with these ranges.

Type:SwitchParameter
Position:Named
Default value:None
Required:False
Accept pipeline input:False
Accept wildcard characters:False

-DeleteAssociatedRanges

Indicates that the cmdlet deletes subnets and any associated ranges. If you do not specify this parameter, the cmdlet generates an error when there are ranges associated with the subnet.

Type:SwitchParameter
Position:Named
Default value:None
Required:False
Accept pipeline input:False
Accept wildcard characters:False

-Force

Forces the command to run without asking for user confirmation.

Type:SwitchParameter
Position:Named
Default value:None
Required:False
Accept pipeline input:False
Accept wildcard characters:False

-InputObject

Specifies the input to this cmdlet. You can use this parameter, or you can pipe the input to this cmdlet.

Type:CimInstance[]
Position:Named
Default value:None
Required:True
Accept pipeline input:True
Accept wildcard characters:False

-NetworkId

Specifies an array of networks for the subnets to remove.

Type:String[]
Position:Named
Default value:None
Required:True
Accept pipeline input:True
Accept wildcard characters:False

-NetworkType

Specifies an array of network types for the subnets to delete.

The acceptable values for this parameter are:

  • Provider -- Customer -- NonVirtualized

    If you do not specify a value, all matching IP subnets of network type Provider, Customer and NonVirtualized will be deleted.

Type:VirtualizationType[]
Accepted values:NonVirtualized, Provider, Customer
Position:Named
Default value:None
Required:False
Accept pipeline input:True
Accept wildcard characters:False

-PassThru

Returns an object representing the item with which you are working. By default, this cmdlet does not generate any output.

Type:SwitchParameter
Position:Named
Default value:None
Required:False
Accept pipeline input:False
Accept wildcard characters:False

-ThrottleLimit

Specifies the maximum number of concurrent operations that can be established to run the cmdlet. If this parameter is omitted or a value of 0 is entered, then Windows PowerShell® calculates an optimum throttle limit for the cmdlet based on the number of CIM cmdlets that are running on the computer. The throttle limit applies only to the current cmdlet, not to the session or to the computer.

Type:Int32
Position:Named
Default value:None
Required:False
Accept pipeline input:False
Accept wildcard characters:False

-WhatIf

Shows what would happen if the cmdlet runs. The cmdlet is not run.

Type:SwitchParameter
Aliases:wi
Position:Named
Default value:False
Required:False
Accept pipeline input:False
Accept wildcard characters:False

Outputs

IpamSubnet

This cmdlet returns an object that represents the subnet deleted from the IPAM Server.
