qos/auto qos config question
Just started studying QoS.
When configuring auto qos for a voip phone, configs for qos need to be on the switch facing the phone, trunk from that swith to another uplink switch, then onto another upstream switch until it reaches a layer 3 device? On all ingress/egress interfaces?
Then on the routers, configs for auto qos need to be set to the neighboring router, the to the switch/es it connect to then to the final dest switch interfaces to the end voip phone?
Also what if that voip traffic traverses - eg mpls routers, qos for mpls like exp bit need to be config'd?
Thanks guys, Ive been looking for a good link but still cant find one that talks about the whole path.
