• The RADIUS or 802.1X server must specify the policy to assign. For example, if the DiffServ policy to assign is named internet_access, include the following attribute in the RADIUS or 802.1X server configuration: Filter-id = "internet_access" • The DiffServ policy specified in the attribute must already be configured on the switch, and the policy names must be identical. For information about configuring a DiffServ policy, see "DiffServ Configuration Examples" on page 1136. The example "Providing Subnets Equal Access to External Network" on page 1136, describes how to configure a policy named internet_access. If you use an authentication server to assign DiffServ policies to an authenticated user, note the following guidelines: • If the policy specified within the server attribute does not exist on the switch, authentication will fail. • Do not delete policies used as the filter ID in the RADIUS server while 802.1X is enabled. • Do not use the DiffServ service-policy command to apply the filter to an interface if you configure the RADIUS server or 802.1X authenticator to assign the DiffServ filter. In the following example, Company XYZ uses IEEE 802.1X to authenticate all users. Contractors and temporary employees at Company XYZ are not permitted to have access to SSH ports, and data rates for Web traffic is limited. When a contractor is authenticated by the RADIUS server, the server assigns a DiffServ policy to control the traffic restrictions. The network administrator configures two DiffServ classes: cl-ssh and cl-http. The class cl-ssh matches all incoming SSH packets. The class cl-http matches all incoming HTTP packets. Then, the administrator configures a traffic policy called con-pol and adds the cl-ssh and cl-http. The policy is configured so that that SSH packets are to be dropped, and HTTP data rates are limited to 1 MB with a burst size of 64 Kbps. HTTP traffic that exceeds the limit is dropped. The host ports, ports 1-23, are configured to use MAC-based dot1X authentication to allow the DiffServ policy to be applied. Finally, the administrator configures the RADIUS server with the attribute Filter-id = "con-pol". 504 Configuring Port and System Security
