5 years ago I ended up writing a new RadiusDictionary that parses the freeradius files. I didn't want to copy and paste a bunch of stuff. It seems to parse fine, but I haven't ran it against anything yet.
Is there any reason those files wouldn't work in your system?
Here is my source if you want to see.
using Flexinets.Radius.Core;
using log4net;
using System;
using System.Collections.Generic;
using System.IO;
using System.Linq;
namespace InfinitWifi.RadiusServer
{
public class RadiusDictionary : IRadiusDictionary
{
private readonly List<DictionaryVendorAttribute> vendorSpecificAttributes = new List<DictionaryVendorAttribute>();
private readonly Dictionary<byte, DictionaryAttribute> attributes = new Dictionary<byte, DictionaryAttribute>();
private readonly Dictionary<string, DictionaryAttribute> attributeNames = new Dictionary<string, DictionaryAttribute>();
private readonly ILog log = LogManager.GetLogger(typeof(RadiusDictionary));
public RadiusDictionary(string dictionaryFilePath)
{
ParseFile(dictionaryFilePath);
log.Info($"Parsed {attributes.Count} attributes and {vendorSpecificAttributes.Count} vendor attributes from file");
}
public DictionaryAttribute GetAttribute(byte code) => attributes[code];
public DictionaryAttribute GetAttribute(string name)
{
attributeNames.TryGetValue(name, out var attributeType);
return attributeType;
}
public DictionaryVendorAttribute GetVendorAttribute(uint vendorId, byte vendorCode) =>
vendorSpecificAttributes.FirstOrDefault(a => a.VendorId == vendorId && a.VendorCode == vendorCode);
private void ParseFile(string dictionaryFilePath)
{
using (var reader = new StreamReader(dictionaryFilePath))
{
var vendorName = string.Empty;
uint vendorId = 0;
while (!reader.EndOfStream)
{
var line = reader.ReadLine();
if (line.StartsWith("$INCLUDE"))
{
var lineParts = SplitLine(line);
var fileName = lineParts[1];
var filePath = Path.Combine(Path.GetDirectoryName(dictionaryFilePath), fileName);
ParseFile(filePath);
}
else if (line.StartsWith("VENDOR"))
{
var lineParts = SplitLine(line);
vendorName = lineParts[1];
vendorId = Convert.ToUInt32(lineParts[2]);
}
else if (line.StartsWith("END-VENDOR"))
{
vendorName = string.Empty;
vendorId = 0;
}
else if (line.StartsWith("ATTRIBUTE"))
{
var lineParts = SplitLine(line);
if (vendorId == 0)
{
var name = lineParts[1];
if (!byte.TryParse(lineParts[2], out var code))
{
continue;
}
var type = lineParts[3];
var attribute = new DictionaryAttribute(name, code, type);
attributes[code] = attribute;
attributeNames[name] = attribute;
}
else
{
var name = lineParts[1];
if (!uint.TryParse(lineParts[2], out var code))
{
continue;
}
var type = lineParts[3];
var attribute = new DictionaryVendorAttribute(vendorId, name, code, type);
vendorSpecificAttributes.Add(attribute);
}
}
}
}
}
private string[] SplitLine(string line)
{
return line.Split(new char[] { '\t', '\x20' }, StringSplitOptions.RemoveEmptyEntries);
}
}
}

Could you explain your vendor format? I'm looking to add some vendors to my file, but I'm seeing differences from the files I have. I'm using ones from WireShark, but they look like they came from FreeRadius. I'm looking at Cisco vendor 9 as an example. Not everything is included in your file. Some of the names match up and some have cisco- in front when it doesn't in the freeradius file. Casing is different. Are values not put in your file?
To me, this looks to be the format:
This is the file I want to use.
