Configuring Auto-QoS
Figure 39-14 Auto-QoS Configuration Example Network
Figure 39-14 shows a network in which the VoIP traffic is prioritized over all other traffic. Auto-QoS is
enabled on the switches in the w
iring closets at the edge of the QoS domain.
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.
