Gotta love it when Cisco adds an automatic QoS configuration command for VoIP network tweaking into its routers.

AutoQoS, a new command in IOS, allows a router to classify types of traffic by importance and ensure that the traffic is passed along as quickly as possible. If necessary, other traffic gets queued until the higher priority traffic has gone through.

The new command is limited in scope but is designed to prioritize VoIP traffic for a "good enough" solution, rather than having to put a network admin through a lot of hoops and pain for router tweaking. AutoQoS speeds up administrator training, makes VoIP often go much smoother and creates config templates that can be modified and copied for deployment as needed.

Configuration requires three commands, one to specify interface, a second to specify bandwidth and a third to invoke AutoQoS for VoIP.
