[Kea-users] Question about vivso (option 125) with suboption config

Tue Apr 16 08:02:14 UTC 2024

Thanks Marek.

That will help me.

Regarding your config, what code 1 and 111 refer to ? is it standard code or it refers to specific suboptions vendor ?

Regards.

A working example from my home lab setup follows

    "option-def": [
      {
        "name": "worldbox_adb_bmc",
        "code": 1,
        "type": "string",
        "space": "vendor-14810",
        "encapsulate": ""
      },
      {
        "name": "vendor-16666-test",
        "code": 111,
        "type": "string",
        "space": "vendor-16666",
        "encapsulate": ""
      }
    ],
    "option-data": [
      {
        "name": "worldbox_adb_bmc",
        "space": "vendor-14810",
        "data": "'some URL from worldbox_adb_bmc'",
        "always-send": true
      },
      {
        "name": "vendor-16666-test",
        "space": "vendor-16666",
        "data": "'some URL from vendor-16666-test'",
        "always-send": true
      },
      {
        "name": "vivso-suboptions",
        "data": "14810",
        "always-send": true
      },
      {
        "name": "vivso-suboptions",
        "data": "16666",
        "always-send": true
      }
    ],

Hi All,

I would like to get a proper configuration for option 125 (vivso), and got some questions hope you guys can help me.

1st question :

Here is my current config for bootfile name :

{

    "subnet4": [ {

        "reservations": [

        {

            "hw-address": "aa:bb:cc:dd:ee:ff",

            "next-server": "10.171.20.254",

            "server-hostname": "10.171.20.72",

            "boot-file-name": " dhcp-ztp.txt"

        } ]

    } ]

}

With this config, the boot file is downloaded from a TFTP server,

How to switch from TFTP to HTTP server? what am I missing on the config?

2nd question : the config below is adapted from an existing vivso config

{

    "option-def": [

    {

        "name": "tftp",

        "code": 2,

        "space": "vendor-1966",

        "type": "string"

    } ],

    "client-classes": [

    {

        "name": "Perle",

        "test": "substring(option[60].hex,0,4) == '1966'",

        "option-data": [

            {

                "name": "vivso-suboptions",

                "data": "1966",

                "encapsulate": "vendor-1966"

            },

            {

                "name": "tftp",

                "space": "vendor-1966",

                "data": "URL file name",

                "always-send": true

            }

        ]

    } ]

}

And below the details of the option125 with suboption from the vendor :

[Une image contenant texte, capture d’écran, Police, ligne    Description générée automatiquement]
[Une image contenant texte, capture d’écran, Police, nombre    Description générée automatiquement]
[Une image contenant texte, capture d’écran, nombre, Police    Description générée automatiquement]

So in HEX format it looks like this:

00:00:07:AE:14:10:01:01:05:0F:73:63:67:2D:36:2E:31:2E:54:32:35:2E:65:6D:67

00:00:07:AE : vendor id

14 : data length in total until the end (HEX format)

Suboption 10 --> define which protocol to use for bootfile/software

01: Data lenght

01: HTTP protocol

Suboption 05 --> define software file name

0F : Data length

73:63:67:2D:36:2E:31:2E:54:32:35:2E:65:6D:67 : File name in HEX format

So my question is :

This format was working with ISC DHCP, however, is it possible to adapt this vivso option and suboption vendor into KEA config ?

it doesn’t need to be in HEX format, as long as it works the same that’s fine.

If yes, how to define in my current config vivso config, the suboption 10 and suboption 5 with their data ?

Thank you.

Regards.

Philippe
