Examples This example shows how to enable auto-QoS and to trust the QoS labels received in incoming packets
when the switch or router connected to the port is a trusted device:
Switch(config)# interface gigabitethernet2/0/1
Switch(config-if)# auto qos voip trust
You can verify your settings by entering the show auto qos interface interface-id privileged EXEC
command.
