Assigning a DSCP policy for a global TCP/UDP classifier

  1. Selects an incoming IP packet if the TCP or UDP port number it carries matches the port number specified in the TCP or UDP classifier (as shown in the figure in Operating notes on using TCP/UDP port ranges).
  2. Overwrites (re-marks) the packet's DSCP with the new DSCP configured for matching packets.
  3. Assigns the 802.1p priority associated with the new DSCP (see Differentiated Services Codepoint (DSCP) mapping).
  4. Forwards the packet through the appropriate outbound port queue.
