how to prioritize Cisco switch wrt video traffic

[kashish884singh]

How a switch can recognize traffic as “video” and what knobs inside a switch are available for a network designer to achieve this requirement???

There are Media net on the switch that can automatically detect the device type connected to the switch and set the video Quality of service properly. But as a network designer what can we control with respect to Traffic prioritization??

Cisco switch series often vary much in their QoS features. Generally, most Cisco enhanced or smart switches can "analyze" traffic via an ACL. Anything beyond that is often unavailable or "rare". Further, most Enterprise grade (or better) switches support some number of hardware egress queues to which various prioritizes might be assigned with perhaps different drop capabilities.
