I have access layer switch, where Cisco IP phones are directly connected.With IP phone,pc is connected. Acees layer switch(4506) is connected with 6509 core switch and 6509 is then connected to 7206 router for WAN connectivity. I want to implement QOS end-to-end. Can you please let me know the best practice and the best way to achieve quality of service starting from acess switch to core switch and on router.
Thanks for your help and support. Following is the configuration which I have done in my devices. I haven't enable any qos under VLAN interface and under interface between Cores witch to WAN router.Is there any need for above? I am not much confortable with wrr/srr queuing, so is it necesaary to define?
Also let me know, if anything else I have to configure.
