Synopsis

Calls the Amazon Elastic Compute Cloud (EC2) DescribeDhcpOptions API operation.

Syntax

Get-EC2DhcpOption
-DhcpOptionsId <String[]>
-Filter <Filter[]>
-MaxResult <Int32>
-NextToken <String>
-Select <String>
-PassThru <SwitchParameter>
-NoAutoIteration <SwitchParameter>

Description

Describes one or more of your DHCP options sets. For more information, see DHCP Options Sets in the Amazon Virtual Private Cloud User Guide.

This cmdlet automatically pages all available results to the pipeline - parameters related to iteration are only needed if you want to manually control the paginated output. To disable autopagination, use -NoAutoIteration.

Parameters

-DhcpOptionsId <String[]>
The IDs of one or more DHCP options sets.Default: Describes all your DHCP options sets.
Required?False
Position?1
Accept pipeline input?True (ByValue, ByPropertyName)
AliasesDhcpOptionsIds
-Filter <Filter[]>
One or more filters.
  • dhcp-options-id - The ID of a DHCP options set.
  • key - The key for one of the options (for example, domain-name).
  • value - The value for one of the options.
  • owner-id - The ID of the AWS account that owns the DHCP options set.
  • tag:<key> - The key/value combination of a tag assigned to the resource. Use the tag key in the filter name and the tag value as the filter value. For example, to find all resources that have a tag with the key Owner and the value TeamA, specify tag:Owner for the filter name and TeamA for the filter value.
  • tag-key - The key of a tag assigned to the resource. Use this filter to find all resources assigned a tag with a specific key, regardless of the tag value.
Required?False
Position?2
Accept pipeline input?True (ByPropertyName)
AliasesFilters
-MaxResult <Int32>
The maximum number of results to return with a single call. To retrieve the remaining results, make another call with the returned nextToken value.
Note: In AWSPowerShell and AWSPowerShell.NetCore this parameter is used to limit the total number of items returned by the cmdlet.
In AWS.Tools this parameter is simply passed to the service to specify how many items should be returned by each service call.
Pipe the output of this cmdlet into Select-Object -First to terminate retrieving data pages early and control the number of items returned.
Required?False
Position?Named
Accept pipeline input?True (ByPropertyName)
AliasesMaxItems, MaxResults
-NextToken <String>
The token for the next page of results.
Note: This parameter is only used if you are manually controlling output pagination of the service API call.
In order to manually control output pagination, use '-NextToken $null' for the first call and '-NextToken $AWSHistory.LastServiceResponse.NextToken' for subsequent calls.
Required?False
Position?Named
Accept pipeline input?True (ByPropertyName)
-NoAutoIteration <SwitchParameter>
By default the cmdlet will auto-iterate and retrieve all results to the pipeline by performing multiple service calls. If set, the cmdlet will retrieve only the next 'page' of results using the value of NextToken as the start point.
Required?False
Position?Named
Accept pipeline input?True (ByPropertyName)
-PassThru <SwitchParameter>
Changes the cmdlet behavior to return the value passed to the DhcpOptionsId parameter. The -PassThru parameter is deprecated, use -Select '^DhcpOptionsId' instead. This parameter will be removed in a future version.
Required?False
Position?Named
Accept pipeline input?True (ByPropertyName)
-Select <String>
Use the -Select parameter to control the cmdlet output. The default value is 'DhcpOptions'. Specifying -Select '*' will result in the cmdlet returning the whole service response (Amazon.EC2.Model.DescribeDhcpOptionsResponse). Specifying the name of a property of type Amazon.EC2.Model.DescribeDhcpOptionsResponse will result in that property being returned. Specifying -Select '^ParameterName' will result in the cmdlet returning the selected cmdlet parameter value.
Required?False
Position?Named
Accept pipeline input?True (ByPropertyName)

Common Credential and Region Parameters

-AccessKey <String>
The AWS access key for the user account. This can be a temporary access key if the corresponding session token is supplied to the -SessionToken parameter.
Required? False
Position? Named
Accept pipeline input? True (ByPropertyName)
Aliases AK
-Credential <AWSCredentials>
An AWSCredentials object instance containing access and secret key information, and optionally a token for session-based credentials.
Required? False
Position? Named
Accept pipeline input? True (ByPropertyName)
-ProfileLocation <String>

Used to specify the name and location of the ini-format credential file (shared with the AWS CLI and other AWS SDKs)

If this optional parameter is omitted this cmdlet will search the encrypted credential file used by the AWS SDK for .NET and AWS Toolkit for Visual Studio first. If the profile is not found then the cmdlet will search in the ini-format credential file at the default location: (user's home directory)\.aws\credentials. Note that the encrypted credential file is not supported on all platforms. It will be skipped when searching for profiles on Windows Nano Server, Mac, and Linux platforms.

If this parameter is specified then this cmdlet will only search the ini-format credential file at the location given.

As the current folder can vary in a shell or during script execution it is advised that you use specify a fully qualified path instead of a relative path.

Required? False
Position? Named
Accept pipeline input? True (ByPropertyName)
Aliases AWSProfilesLocation, ProfilesLocation
-ProfileName <String>
The user-defined name of an AWS credentials or SAML-based role profile containing credential information. The profile is expected to be found in the secure credential file shared with the AWS SDK for .NET and AWS Toolkit for Visual Studio. You can also specify the name of a profile stored in the .ini-format credential file used with the AWS CLI and other AWS SDKs.
Required? False
Position? Named
Accept pipeline input? True (ByPropertyName)
Aliases AWSProfileName, StoredCredentials
-NetworkCredential <PSCredential>
Used with SAML-based authentication when ProfileName references a SAML role profile. Contains the network credentials to be supplied during authentication with the configured identity provider's endpoint. This parameter is not required if the user's default network identity can or should be used during authentication.
Required? False
Position? Named
Accept pipeline input? True (ByPropertyName)
-SecretKey <String>
The AWS secret key for the user account. This can be a temporary secret key if the corresponding session token is supplied to the -SessionToken parameter.
Required? False
Position? Named
Accept pipeline input? True (ByPropertyName)
Aliases SecretAccessKey, SK
-SessionToken <String>
The session token if the access and secret keys are temporary session-based credentials.
Required? False
Position? Named
Accept pipeline input? True (ByPropertyName)
Aliases ST
-Region <String>
The system name of the AWS region in which the operation should be invoked. For example, us-east-1, eu-west-1 etc.
Required? False
Position? Named
Accept pipeline input? True (ByPropertyName)
Aliases RegionToCall
-EndpointUrl <String>

The endpoint to make the call against.

Note: This parameter is primarily for internal AWS use and is not required/should not be specified for normal usage. The cmdlets normally determine which endpoint to call based on the region specified to the -Region parameter or set as default in the shell (via Set-DefaultAWSRegion). Only specify this parameter if you must direct the call to a specific custom endpoint.

Required? False
Position? Named
Accept pipeline input? True (ByPropertyName)

Inputs

System.String[]
You can pipe a String[] object to this cmdlet for the DhcpOptionsId parameter.

Outputs

Amazon.EC2.Model.DhcpOptions or Amazon.EC2.Model.DescribeDhcpOptionsResponse
This cmdlet returns a collection of Amazon.EC2.Model.DhcpOptions objects. The service call response (type Amazon.EC2.Model.DescribeDhcpOptionsResponse) can also be referenced from properties attached to the cmdlet entry in the $AWSHistory stack.

Examples

Example 1

PS C:\> Get-EC2DhcpOption

DhcpConfigurations                    DhcpOptionsId    Tag
------------------                    -------------    ---
{domain-name, domain-name-servers}    dopt-1a2b3c4d    {}
{domain-name, domain-name-servers}    dopt-2a3b4c5d    {}
{domain-name-servers}                 dopt-3a4b5c6d    {}
This example lists your DHCP options sets.

Example 2

PS C:\> (Get-EC2DhcpOption -DhcpOptionsId dopt-1a2b3c4d).DhcpConfigurations

Key                    Values
---                    ------
