Auto-QoS Configuration Example
Auto-QoS Configuration Example
This section describes how you could implement auto-QoS in a network, a s shown in Figure 23-3. For
optimum QoS performance, auto-QoS should be enabled on all the devices in the network.
Figure23-3 Auto-QoS Configuration Example Network
The intelligent wiring closets in Figure23-3 are co mposed of Catalyst 2950 switches running the EI and
Catalyst 3550 switches. The object of this 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 s o only after the auto-QoS
configuration is completed.
