Options

--traffic-mirror-session-id (string)

The ID of the Traffic Mirror session.

--traffic-mirror-target-id (string)

The Traffic Mirror target. The target must be in the same VPC as the source, or have a VPC peering connection with the source.

--traffic-mirror-filter-id (string)

The ID of the Traffic Mirror filter.

--packet-length (integer)

The number of bytes in each packet to mirror. These are bytes after the VXLAN header. To mirror a subset, set this to the length (in bytes) to mirror. For example, if you set this value to 100, then the first 100 bytes that meet the filter criteria are copied to the target. Do not specify this parameter when you want to mirror the entire packet.

For sessions with Network Load Balancer (NLB) traffic mirror targets, the default PacketLength will be set to 8500. Valid values are 1-8500. Setting a PacketLength greater than 8500 will result in an error response.

--session-number (integer)

The session number determines the order in which sessions are evaluated when an interface is used by multiple sessions. The first session with a matching filter is the one that mirrors the packets.

Valid values are 1-32766.

--virtual-network-id (integer)

The virtual network ID of the Traffic Mirror session.

--description (string)

The description to assign to the Traffic Mirror session.

--remove-fields (list)

The properties that you want to remove from the Traffic Mirror session.

When you remove a property from a Traffic Mirror session, the property is set to the default.

(string)

Syntax:

"string" "string" ...

Where valid values are:
  packet-length
  description
  virtual-network-id

--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 .

--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. It is not possible to pass arbitrary binary values using a JSON-provided value as the string will be taken literally.

--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.

Global Options

--debug (boolean)

Turn on debug logging.

--endpoint-url (string)

Override command's default URL with the given URL.

--no-verify-ssl (boolean)

By default, the AWS CLI uses SSL when communicating with AWS services. For each SSL connection, the AWS CLI will verify SSL certificates. This option overrides the default behavior of verifying SSL certificates.

--no-paginate (boolean)

Disable automatic pagination.

--output (string)

The formatting style for command output.

  • json
  • text
  • table

--query (string)

A JMESPath query to use in filtering the response data.

--profile (string)

Use a specific profile from your credential file.

--region (string)

The region to use. Overrides config/env settings.

--version (string)

Display the version of this tool.

--color (string)

Turn on/off color output.

  • on
  • off
  • auto

--no-sign-request (boolean)

Do not sign requests. Credentials will not be loaded if this argument is provided.

--ca-bundle (string)

The CA certificate bundle to use when verifying SSL certificates. Overrides config/env settings.

--cli-read-timeout (int)

The maximum socket read time in seconds. If the value is set to 0, the socket read will be blocking and not timeout. The default value is 60 seconds.

--cli-connect-timeout (int)

The maximum socket connect time in seconds. If the value is set to 0, the socket connect will be blocking and not timeout. The default value is 60 seconds.

Examples

Note

To use the following examples, you must have the AWS CLI installed and configured. See the Getting started guide in the AWS CLI User Guide for more information.

Unless otherwise stated, all examples have unix-like quotation rules. These examples will need to be adapted to your terminal's quoting rules. See Using quotation marks with strings in the AWS CLI User Guide .

To modify a traffic mirror session

The following modify-traffic-mirror-session example changes the traffic mirror session description and the number of packets to mirror.

aws ec2 modify-traffic-mirror-session \
    --description "Change packet length" \
    --traffic-mirror-session-id tms-08a33b1214EXAMPLE \
    --remove-fields "packet-length"

Output:

{
    "TrafficMirrorSession": {
        "TrafficMirrorSessionId": "tms-08a33b1214EXAMPLE",
        "TrafficMirrorTargetId": "tmt-07f75d8feeEXAMPLE",
        "TrafficMirrorFilterId": "tmf-04812ff784EXAMPLE",
        "NetworkInterfaceId": "eni-070203f901EXAMPLE",
        "OwnerId": "111122223333",
        "SessionNumber": 1,
        "VirtualNetworkId": 7159709,
        "Description": "Change packet length",
        "Tags": []
    }
}
