The intelligent wiring closets in
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.
You should not configure any standard-QoS commands before entering the auto-QoS commands. You
Note
can fine-tune the QoS configuration, but we recommend that you do so only after the auto-QoS
configuration is completed.
