It provides an easy way for performing andmanaging QoS configuration. A QoS profile can contain one or multiple QoS actions. Innetworks where hosts change their positions frequently, you can define QoS policies forthe specific hosts and add the QoS policies to a QoS profile. When a host is connected toanother port of a switch, you can simply apply the corresponding QoS profile to the portstatically or dynamically to maintain the same QoS configuration performed for the host.Currently, a QoS profile can contain configurations concerning packet filtering, trafficpolicing, and priority marking.QoS Profile Application ModeDynamic application modeA QoS profile can be applied dynamically to a user or a group of users passing 802.1xauthentication. To apply QoS profiles dynamically, a user name-to-QoS profile mappingtable is required on the AAA server. For a switch operating in this mode, after a user passesthe 802.1x authentication, the switch looks up the user name-to-QoS profile mapping tablefor the QoS profile using the user name and then applies the QoS profile found to the portthe user is connected to.Corresponding to the 802.1x authentication modes, dynamic QoS profile application canbe user-based and port-based.z User-based QoS profile applicationThe switch generates a new QoS profile by adding user source MAC address informationto the identifying rule defined in the existing QoS profile and then applies the new QoSprofile to the port the user is connected to.z Port-based QoS profile applicationThe switch directly applies the QoS profile to the port the user is connected to.
