Examples: Auto-QoS Generated Configuration for VoIP Devices
If you entered the auto qos voip cisco-phone command, the switch automatically enables the trusted boundary
feature, which uses the CDP to detect the presence or absence of a Cisco IP Phone.
Switch(config-if)# mls qos trust device cisco-phone
If you entered the auto qos voip cisco-softphone command, the switch automatically creates class maps and
policy maps.

Switch(config)# class-map match-all AutoQoS-VoIP-RTP-Trust
Switch(config-cmap)# match ip dscp ef
Switch(config)# class-map match-all AutoQoS-VoIP-Control-Trust
