3. Only "switch-style" QoS, not full-blown MQC. The 3750ME has two "router" ports which do mostly support MQC, but still have some limitations (e.g. traffic locally sourced from the device is not correctly classified / marked). Which is all kind of what you'd expect from a switch, but may be relevent if the original question was "which router?" Regards, Tim.
