Chapter 36 Configuring QoS
Configuring Auto-QoS
Auto-QoS Configuration Example
This section describes how you could implement auto-QoS in a network, as shown in
Figure 36-10
. For
optimum QoS performance, enable auto-QoS on all the devices in the network.
Figure 36-10
Auto-QoS Configuration Example Network
Figure 36-10
shows a network in which the VoIP traffic is prioritized over all other traffic. Auto-QoS is
enabled on the switches in the wiring 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.
