11-111 User Profile ConfigurationWhen configuring user profile, go to these sections for information you are interested in:z User Profile Overviewz User Profile Configurationz Displaying and Maintaining User ProfileUser Profile OverviewUser profile provides a configuration template to save predefined configurations. Based on differentapplication scenarios, you can configure different items for a user profile, such as Committed AccessRate (CAR), Quality of Service (QoS), and so on.When accessing the device, users need to be authenticated. During the authentication process, theauthentication server sends the user profile name to the device, which then enables the configurationsin the user profile. After the users pass the authentication and access the device, the device will restrictthe users’ access based on these configurations. When the users log out, the device automaticallydisables the configurations in the user profile, and thus the restrictions on the users are removed.Therefore, user profile is applicable to restricting online users’ access; if no users are online (no useraccess, no users pass the authentication, or users have logged out), user profile does not take effectas it is a predefined configuration.With user profile, you can:z Make use of system resources more granularly. For example, without user profile, you can apply aQoS policy based on interface, VLAN, globally and so on. This QoS policy is applicable to a groupof users. With user profile, however, you can apply a QoS policy on a per-user basis.z Restrict users’ access to the system resources more flexibly. For example, without user profile,you can perform traffic policing based on CAR, ACL, or for all the traffic of the current interface;when the physical position of users changes (for example, the users access the network usinganother interface), you need to configure traffic policing on another interface. With user profile,however, you can perform traffic policing on a per-user basis. As long as users are online, theauthentication server applies the corresponding user profile (with CAR configured) to the users;when the users are offline, the system automatically removes the corresponding configuration.User Profile ConfigurationUser Profile Configuration Task ListTask RemarksCreating a User Profile RequiredApplying a QoS Policy to User Profile RequiredEnabling a User Profile Required
