Re: OT: Catalys 6500 qos policing doubts

Just curious is the 'platform' new to ios 15?

platform qos queue-mode mode-dscp

Is that this command?

mls qos queue-mode mode-dscp

To set the queuing mode to Differentiated Services Code Point (DSCP) on an
interface, use the *mls qos queue-mode mode-dscp*command in interface
configuration mode. To return to the default settings, use the *no* form of
this command.

*mls qos queue-mode mode-dscp*

*no mls qos queue-mode mode-dscp*
