DescribeDhcpOptions - Amazon Elastic Compute Cloud

DescribeDhcpOptions

Describes your DHCP option sets. The default is to describe all your DHCP option sets. Alternatively, you can specify specific DHCP option set IDs or filter the results to include only the DHCP option sets that match specific criteria.

For more information, see DHCP option sets in the Amazon VPC User Guide.

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
