IP layer's ToS is not passing through MRF Diameter.
The ToS from the client does not reach the server.
-- The IP ToS bit is received in the clientside connection. -- ip-tos-to-client is set as pass-through.
Use an iRule to preserve the ToS from the client and set it to serverside's connection.
The ToS bit that arrives from the clientside connection is able to pass-through with Diameter MRF.
