Synopsis

  describe-vpc-classic-link-dns-support
[--max-results <value>]
[--next-token <value>]
[--vpc-ids <value>]
[--cli-input-json <value>]
[--generate-cli-skeleton <value>]

Options

--max-results (integer)

The maximum number of items to return for this request. The request returns a token that you can specify in a subsequent call to get the next set of results.

--next-token (string)

The token for the next set of items to return. (You received this token from a prior call.)

--vpc-ids (list)

One or more VPC IDs.

Syntax:

"string" "string" ...

--cli-input-json (string) Performs service operation based on the JSON string provided. The JSON string follows the format provided by --generate-cli-skeleton. If other arguments are provided on the command line, the CLI values will override the JSON-provided values.

--generate-cli-skeleton (string) Prints a JSON skeleton to standard output without sending an API request. If provided with no value or the value input, prints a sample input JSON that can be used as an argument for --cli-input-json. If provided with the value output, it validates the command inputs and returns a sample output JSON for that command.
