Also while hunting for Job , most are looking for this QoS knowledge. Hands down clear. Now time to rewatch and possibly watch your CCNP version of QoS ...Thank you again sir, you're the best.

as a non-network engineer I propose RFC amendment, the severity levels on PCP and in general syslogs go in opposite directions of each other. wherein syslog severity codes 0 is the most severe level and 7 is debugging severity being the least severe, PCP uses 0 for the least important traffic and 7 for the most important traffic, can we switch one of them around? I'd vote PCP because its a lot more specific of a use case then general logging and everyone is already used to syslog codes being read the way they are and its probably deeply engrained.
