76 CHAPTER 6: USING TRAFFIC PRIORITIZATION Table 9 Example QoS profile rules Rule Example Port-based Set all traffic received on a port to a particular DiffServ Code Point (DSCP). Priority re-mapping Mark the 802.1D priority of each packet on a port according to its DSCP to ensure correct priority treatment by non-DiffServ devices on the network. Endstation based Prioritize packets (by DSCP or 802.1D) destined for a particular endstation or server in the network. Network protocol based Prioritize IP traffic over IPX. NBX phone traffic Prioritize over data traffic. Layer 4 port number Prioritize Lotus Notes traffic over web (HTTP) traffic.
