Options

--client-vpn-endpoint-id (string)

The ID of the Client VPN endpoint to modify.

--server-certificate-arn (string)

The ARN of the server certificate to be used. The server certificate must be provisioned in AWS Certificate Manager (ACM).

--connection-log-options (structure)

Information about the client connection logging options.

If you enable client connection logging, data about client connections is sent to a Cloudwatch Logs log stream. The following information is logged:

• Client connection requests

• Client connection results (successful and unsuccessful)

• Reasons for unsuccessful client connection requests

• Client connection termination time

Enabled -> (boolean)

Indicates whether connection logging is enabled.

CloudwatchLogGroup -> (string)

The name of the CloudWatch Logs log group. Required if connection logging is enabled.

CloudwatchLogStream -> (string)

The name of the CloudWatch Logs log stream to which the connection data is published.

Shorthand Syntax:

Enabled=boolean,CloudwatchLogGroup=string,CloudwatchLogStream=string

JSON Syntax:

{
  "Enabled": true|false,
  "CloudwatchLogGroup": "string",
  "CloudwatchLogStream": "string"
}

--dns-servers (structure)

Information about the DNS servers to be used by Client VPN connections. A Client VPN endpoint can have up to two DNS servers.

CustomDnsServers -> (list)

The IPv4 address range, in CIDR notation, of the DNS servers to be used. You can specify up to two DNS servers. Ensure that the DNS servers can be reached by the clients. The specified values overwrite the existing values.

(string)

Enabled -> (boolean)

Indicates whether DNS servers should be used. Specify False to delete the existing DNS servers.

Shorthand Syntax:

CustomDnsServers=string,string,Enabled=boolean

JSON Syntax:

{
  "CustomDnsServers": ["string", ...],
  "Enabled": true|false
}

--vpn-port (integer)

The port number to assign to the Client VPN endpoint for TCP and UDP traffic.

Valid Values: 443 | 1194

Default Value: 443

--description (string)

A brief description of the Client VPN endpoint.

--split-tunnel | --no-split-tunnel (boolean)

Indicates whether the VPN is split-tunnel.

For information about split-tunnel VPN endpoints, see Split-Tunnel AWS Client VPN Endpoint in the AWS Client VPN Administrator Guide .

--dry-run | --no-dry-run (boolean)

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 .

--security-group-ids (list)

The IDs of one or more security groups to apply to the target network.

(string)

Syntax:

"string" "string" ...

--vpc-id (string)

The ID of the VPC to associate with the Client VPN endpoint.

--cli-input-json | --cli-input-yaml (string) Reads arguments from the JSON string provided. The JSON string follows the format provided by --generate-cli-skeleton. If other arguments are provided on the command line, those values will override the JSON-provided values. It is not possible to pass arbitrary binary values using a JSON-provided value as the string will be taken literally. This may not be specified along with --cli-input-yaml.

--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. Similarly, if provided yaml-input it will print a sample input YAML that can be used with --cli-input-yaml. If provided with the value output, it validates the command inputs and returns a sample output JSON for that command.

--cli-auto-prompt (boolean) Automatically prompt for CLI input parameters.

See ‘aws help’ for descriptions of global parameters.

Examples

To modify a Client VPN endpoint

The following modify-client-vpn-endpoint example enables client connection logging for the specified Client VPN endpoint.

aws ec2 modify-client-vpn-endpoint \
    --client-vpn-endpoint-id cvpn-endpoint-123456789123abcde \
    --connection-log-options Enabled=true,CloudwatchLogGroup=ClientVPNLogs

Output:

{
    "Return": true
}

For more information, see Client VPN Endpoints in the AWS Client VPN Administrator Guide.

Output

Return -> (boolean)

Returns true if the request succeeds; otherwise, it returns an error.
