Command Mode Interface Configuration
Usage Guideline The DSCP to CoS map is used by the DSCP trust port to map the DSCP value to
an internal CoS value, which will be in turn be mapped to the CoS queue based
on the CoS to queue map configured by the qos map cos command.
Only physical ports are valid for this command. All of the DSCP-to-CoS maps are
globally defined. The map applies to all ports.
Example This example configures the DSCP to CoS map for mapping DSCP 12, 16, 18 to
CoS 1 for eth2.6.
Use the show qos interface map privileged EXEC command to verify the
settings.
