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.

Fix Information

The ToS bit that arrives from the clientside connection is able to pass-through with Diameter MRF.
