Request Parameters

The following parameters are for this specific action. For more information about required and optional parameters that are common to all actions, see Common Query Parameters.

DhcpOptionsId.N

The IDs of DHCP option sets.

Type: Array of strings

Required: No

DryRun

Checks whether you have the required permissions for the action, without actually making the request, and provides an error response. If you have the required permissions, the error response is DryRunOperation. Otherwise, it is UnauthorizedOperation.

Filter.N

The 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 - 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.
