Hi There,
I have a laptop running some software which is sending UDP packets marking it with DSCP value. I have configured switch port to trust the DSCP values using command "mls qos trust dcsp" . On the same switch say port 48 is connecting to my WAN. The problem is when i sniff packets using wireshark from the port on which laptop is connected i can see the dscp markings but when i sniff the packets from port 48 connecting to WAN i see the markings are missing even though ther are on the same switch. for some reason switch is stripping off my dscp markings not sure why? turning on mls qos globally will fixed the issue?.please help me with this. we are setting up some new phone system so they are running this test to make sure QOS is working on our network which is not the case at present.
Thanks,
