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
Table 33-5
Enhanced Auto-QoS for Video, Trust, and Classification
Note
The enhanced auto-QoS feature is not supported on switches running LAN Lite images.
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:
