Configuring Auto-QoS

Auto-QoS Configuration Example

This section describes how you could implement auto-QoS in a network, as shown in

The intelligent wiring closets in
example is to prioritize the VoIP traffic over all other traffic. To do so, enable auto-QoS on the switches
at the edge of the QoS domains in the wiring closets.
Note You should not configure any standard QoS commands before entering the auto-QoS commands. You
can fine-tune the QoS configuration, but we recommend that you do so only after the auto-QoS
configuration is completed.
