QoS command on 4948E switches

[ankit.nigam]

hi,

I have two 3750 switches and have to replace them with 4948E switches. The current 3750 switches have "mls qos"enabled in global mode but

the same command is not being accepted on the 4948E switches. Is there a way to configure " mls qos " on 4948E or is there an alternate command.

Thanks !!

The 4948E has a (quite) different QoS architecture from the 3750 series.  The QoS commands are (quite) different.

Thanks Joseph !! Is there any alternate command for "mls qos" that you are aware of and can be used. The 3750 switches don't have QoS on the interface level just the global "mls qos" , QoS enabling command that I need to translate into 4948E switches.

The 4948E should have global QoS commands that start with the keyword "qos".

Is there a simulator available to test 4948E commands on IOS 15.2(3) E.
