Configuring Quality of Service 711
Auto VoIPVoice over Internet Protocol (VoIP) allows you to make telephone calls using a computer network over a
data network like the Internet. With the increased prominence of delay-sensitive applications (voice,
video, and other multimedia applications) deployed in networks today, proper QoS configuration will
ensure high-quality application performance. The Auto VoIP feature is intended to provide an easy
classification mechanism for voice packets so that they can be prioritized above data packets in order to
provide better QoS.
The Auto VoIP feature explicitly matches VoIP streams in Ethernet switches and provides them with a
better class of service than ordinary traffic. If you enable the Auto VoIP feature on an interface, the
interface scans incoming traffic for the following call-control protocols:
• Session Initiation Protocol (SIP)
•H.323
• Skinny Client Control Protocol (SCCP)
When a call-control protocol is detected the switch assigns the traffic in that session to the highest CoS
queue, which is generally used for time-sensitive traffic.
