mls qos on a vIOS_L2 switch

[saipranav013@gmail.com]

Hi,
  I am studying QoS in vIOS_L2 switch. When I configure QoS globally by entering the command

vIOS-L2-01(config)#mls qos
it gives me an error
% Invalid input detected at '^' marker.
Any help regarding this will be greatly appreciated. Thanks in advance

This feature is not supported on vios_l2 switch on GNS3

some features do not work as expected like in physical hardware.
