Why have we got 2 types of services that do the same thing ( CoS and DSCP ) or have I got it wrong.
Am I right in saying that Cos is layer 2 and DSCP is Layer 3 and that is why we have to map them ???
I have been trying to find out this info but cant get a straight answer anywhere, just how to configure them ??
Please help someone, just explain each one and their role in English and mainly the difference between the two.
Thanks for any help.
