Description
Sets a port to mask the three least significant bits of the DSCP when
the switch is using the DSCP to classify bridged IP traffic. If you
mask the three least significant bits of the DSCP, the switch
recognizes the remaining bits as the precedence field of the Type of
Service (ToS) field and classifies the packets accordingly.
