Enhanced Auto-QoS for Video, Trust, and Classification
In Cisco IOS Release 12.2(55)SE, auto-QoS is enhanced to support video. Automatic configurations are
generated that classify and trust traffic from Cisco TelePresence systems and Cisco IP cameras.
When you configure the auto qos {video | classify | trust} enhanced commands on a switch port, this
behavior occurs:

Auto-QoS Configuration Migration
Auto-QoS configuration migration from legacy auto-QoS to enhanced auto-QoS occurs when:

When you enable auto-QoS by using the auto qos voip cisco-phone, the auto qos voip
cisco-softphone, or the auto qos voip trust interface configuration command, the switch
automatically generates a QoS configuration based on the traffic type and ingress packet label and
applies the commands listed in
Auto qos voip generated commands that you configured on the interface before Cisco IOS Release
12.2(55)SE migrate to the enhanced commands.
Global values change with the migration of enhanced commands. For a complete list of the
generated commands that are applied to the running configuration see
A switch is booted with a 12.2(55)SE image and QoS is not enabled.
Any video or voice trust configuration on the interface automatically generates enhanced auto-QoS
commands.
