[Kea-users] FW: Vendor Encapsulated Options (option 43)

[Sutherland, Rob]

I seem to have resolved my issue with help from Duane Wylie. What worked for me was this:

  "client-classes": [
  {
      "name": "mitel",
      "test": "substring(option[60].hex,0,17) == 'ipphone.mitel.com'",
      "option-def": [
          {
              "name": "vendor-encapsulated-options",
              "code": 43,
              "type": "string"
          }
      ],
      "option-data": [
      {
          "name": "vendor-encapsulated-options",
          "data": "id:ipphone.mitel.com;sw_tftp=10.151.75.34;call_srv=10.151.75.32"
      }
    ]
  },

Subject: [External Source] [Kea-users] Vendor Encapsulated Options (option 43)

I'm taking another stab at evaluating Kea (1.3.0) and am seeing an issue that I saw earlier with respect to Vendor Encapsulated Options (option 43).

With the old ISC DHCP, I can define something like this:

option MitelVendorOptions code 43 = string;
option MitelVendorOptions "id:ipphone.mitel.com;sw_tftp=10.150.5.32;call_srv=10.150.5.32,10.150.95.34";

The packets to the phone with then have the form 0x2b (43) <some_length> <the string>

With Kea, I have yet to find a way to replicate this sicne I HAVE to specify a code. The option then becomes:
0x2b (43) <some_length> <option code I must specify> <another length> <the string>

This extra is causing some phone models to behave incorrectly.

Q: How can I achieve this?

Here's a snippet of my configuration:

    "option-def": [
        {
            "name": "mitel-options",
            "space": "vendor-encapsulated-options-space",
            "code": 1,
            "type": "string",
            "space": "mitel"
        }
...
      "option-data": [
      {
          "name": "mitel-options",
          "space": "mitel",
          "data": "id:ipphone.mitel.com;sw_tftp=10.151.75.34;call_srv=10.151.75.32"
      },
      {
          "name": "vendor-encapsulated-options"
      }
    ]

Thanks,

Rob
