The L2TP CSURQ command expects the local tunnel-id and a list of remote
session-id for which a connect speed update is requested.

.. code-block:: json

    {
        "command": "l2tp-csurq",
        "arguments": {
            "tunnel-id": 1,
            "sessions": [
                1,
                2,
                3,
                4
            ]
        }
    }

This command can be executed as shown below using the CLI tool.

``$ sudo bngblaster-cli run.sock l2tp-csurq tunnel-id 1 sessions [1,2,3,4]``

The L2TP session terminate command allows to test result (RFC2661) and disconnect (RFC3145) codes.

``$ sudo bngblaster-cli run.sock l2tp-session-terminate session-id 1 result-code 2 error-message "LCP request" disconnect-code 3 disconnect-message "LCP terminate request"``
