QoS - auto qos trust

On a Cisco switch that employs QoS, the auto qos trust command generates a set of predefined QoS parameters for all trusted interfaces within the QoS domain. These parameters are the most commonly deployed QoS mechanisms to ensure that VoIP, routing protocol traffic, STP traffic, and real time video traffic are treated appropriately. The command will create a series of policy maps and class maps with the prefix “AutoQos”. These are actually generated as if they were all entered from the CLI.
