Configuring A Qos Policy - Cisco 2950 - Catalyst Switch Configuration Manual

Configuring Standard QoS
To disable pass-through mode, use the no mls qos trust pass-through dscp interface configuration
command.
If you enter the mls qos cos override and the mls qos trust [cos | dscp] interface commands when
pass-through mode is enabled, pass-through mode is disabled.
If you enter the mls qos trust cos pass-through dscp interface configuration command when the mls
qos cos override and the mls qos trust [cos | dscp] interface commands are already configured,
pass-through mode is disabled.
