I would like to build my own dissector based on the parameter severals values of cip.class. I used the function dissector_add_uint("cip.class",VALUE,handle), but it is not working. My dissector is never called.

After research, I think it is because cip.class is not registered, right ? How can I do for use this parameter ?

I see (by trying) that I can use cip.class.iface with value 0. But I don't know what is the attribute, it is never displayed and I don't find where it is read. Someone know where I can find this information ?

Thanks, IJK

Hi, I think you are mixing filter names and dissector tables. To be able to register in a dissector table the table has to be registered first. You can find existing tables and what's registered in them in the "internals" menu in the top menubar.
