Hi Fernando,

we are doing it like that:

        "option-def": [
          {
            "array": false,
            "code": 1,
            "encapsulate": "",
            "name": "DHCP-server-1",
            "record-types": "",
            "space": "PC-MTA",
            "type": "ipv4-address"
          },
          {
            "array": false,
            "code": 6,
            "encapsulate": "",
            "name": "KERBEROS-realm",
            "record-types": "",
            "space": "PC-MTA",
            "type": "string"
          },
          {
            "array": false,
            "code": 3,
            "encapsulate": "",
            "name": "provision-server",
            "record-types": "",
            "space": "PC-MTA",
            "type": "string"
          },
{
            "array": false,
            "code": 122,
            "encapsulate": "PC-MTA",
            "name": "PC-MTA",
            "record-types": "",
            "space": "dhcp4",
            "type": "empty"
          }
        ],

Later: 

                "option-data": [
                  {
                    "always-send": true,
                    "code": 3,
                    "csv-format": false,
                    "data": "0006646F637369730361766D026465",
                    "name": "provision-server",
                    "space": "PC-MTA"
                  },
                  {
                    "always-send": true,
                    "code": 6,
                    "csv-format": false,
                    "data": "0542415349430131",
                    "name": "KERBEROS-realm",
                    "space": "PC-MTA"
                  },
                  {
                    "always-send": true,
                    "code": 1,
                    "csv-format": true,
                    "data": “X.X.X.X",
                    "name": "DHCP-server-1",
                    "space": "PC-MTA"
                  },

Sending the HEX parts via API is a little bit tricky and cost me some time.

Hopefully that helps you.

Best Regards,

Mathias Aichinger
