Hi, I have a problem regarding QoS replies. I am simulating two 4500 switches (A and B) connected by a trunk link. The two switches have one laptop directly connected to each of them (LA for switch A and LB for switch B). I then set the ports connected to the laptops to a default dscp value of 5 (qos dscp 5). Then I performed a ping test from LA to LB.
Am I correct to assume that any packets from LA will be ALWAYS marked with dscp 5 and reach LB with the same mark?
I also noticed that if the request has a mark of dscp 5, the reply is always marked down to 0. Is this a normal behavior even though I configured its port to qos dscp 5 also?
If this is the case then is it safe to assume that a reply will always be marked with a value of 0?
