auto qos...

either auto qos or manual configuration, never both...

remove manual qos before implementing auto qos

auto qos runs a macro that makes assumption about the network and configures according to those assumptions

auto qos:

   globally enables qos

   configures the switch port for incoming cos parameters

   globally configures thresholds and queues

   configures traffic shaping for the port on which it is enabled
