Nortel has adviced us to set access ports on our 3560 switchs to "mls qos dscp trust." Upon testing, I notice that when I do the "msl qos int status" command, that packets marked dscp 46 show up proberly on the "incoming dscp" field, but in the "outgoing dscp" field they are maked to zero. Why is the switch marking down the packets with the trust command in place? The expedite queue is also enabled.
Can anybody explain this?
