1-2server learns the MAC addresses of all the clients, it registers the MAC addresses as HABP entries.Then, link layer frames exchanged between the clients can bypass the 802.1X authentication on portsof the server without affecting the normal operation of the whole network. All HABP packets must travelin a specified VLAN. Communication between the HABP server and the HABP clients is implementedthrough this VLAN.z In a cluster, if a member device with 802.1X authentication or MAC authentication enabled isattached with some other member devices of the cluster, you also need to configure HABP serveron this device. Otherwise, the cluster management device will not be able to manage the devicesattached to this member device.z For more information about the cluster function, refer to Cluster Management Configuration in theSystem Volume.Configuring HABPComplete the following tasks to configure HABP:z Configuring the HABP Serverz Configuring an HABP ClientConfiguring the HABP ServerHABP server is usually configured on the authentication device enabled with 802.1X authentication orMAC address authentication. The HABP server sends HABP requests to the attached switches at aspecified interval, collecting their MAC addresses from the responses. HABP packets are transmitted inthe VLAN specified on the HABP server..You can configure the interval of sending HABP requests on the administrative device.Follow these steps to configure an HABP server:To do… Use the command… RemarksEnter system view system-view —Enable HABP habp enable OptionalEnabled by defaultConfigure HABP to work inserver mode and specify theVLAN for HABP packetshabp server vlan vlan-id RequiredHABP works in client mode by default.Set the interval to send HABPrequests habp timer interval Optional20 seconds by defaultConfiguring an HABP ClientHABP client is usually configured on each device that is attached to the authentication device. Afterreceiving an HABP request from the HABP server, an HABP client responds to the request, deliveringits MAC address to the server, and forwards the HABP request to its attached switches.
