Hi all,
I tried in the forum pages but i haven’t found an answer.
What is the default behavior of ros when forwarding already Tos/DSCP marked packets?
I have (voip) devices sending out already ToS/DSCP marked packets, and between I have some mikrotik routers and I want to know if ros priotizes this kind of traffic over “normal” one by default, without the adding of queues or similar.
Thank You
Unfortunately there is no default priority for DSCP/ToS (or for anything else), you have to create your own queues. As default Ros treats everything at the highest level of priority. Basically you have to create a queue for DSCP/ToS and lower everything else.

Thank You,
that was my fear. Anyway put up a queue is not such a bad thing.
