hook up a packet sniffer and watch the traffic. Wireshark is very common, but cisco also offers the EPC.
You can read more about the EPC here:

Hello Ciprian,
a single diagram covering all the features you have mentioned does not exist probably.
you should look at different documents like
C6500 architecture
C6500 QoS
be aware that QoS implementation in multilayer switches is different from that of routers and also there are big changes among different switch platform.
SW based router platforms implement the different stages in software.
Hope to help
