I want to be able, to add some own Subdissectors for Vendor Specific MSTP
Frames. For that I used a subdissector table.
Frame Types from 0 to 127 are reserved by ASHRAE. The Frame Types from 128 to
255 are available to vendors for non-BACnet Frames, you need to write the
Vendor ID to the first two octets.
With this patch you could register your own dissector with VendorID and Frame
Type from 8 to 255 while using a LUA Script:
do
local mstp_frametype_table = DissectorTable.get("mstp.prop")
local ip_dissector = Dissector.get("ip")
-- ((VendorID << 16) + Frametype)
mstp_frametype_table:add((159 * 256 * 256) + 159,ip_dissector)
mstp_frametype_table:add((159 * 256 * 256) + 160,ip_dissector)
end
(How to add a second (capture-) file here? .. Please e-mail to me, if usefull.)
