1-2HABP is a link layer protocol that works above the MAC layer. It is built on the client-server model.Generally, the HABP server is assumed by the management device (such as Switch A in the aboveexample), and the attached switches function as the HABP clients, such as Switch B through Switch Ein the example. No device can function as both an HABP server and a client at the same time. Typically,the HABP server sends HABP requests to all its clients periodically to collect their MAC addresses, andthe clients respond to the requests. After the server learns the MAC addresses of all the clients, itregisters the MAC addresses as HABP entries. Then, link layer frames exchanged between the clientscan bypass the 802.1X authentication on ports of the server without affecting the normal operation ofthe whole network. All HABP packets must travel in a VLAN, which is called the management VLAN.Communication between the HABP server and the HABP clients is implemented through themanagement VLAN.Configuring HABPComplete the following tasks to configure HABP:z Configuring the HABP Serverz Configuring an HABP ClientConfiguring the HABP ServerYou need to configure the management device as the HABP server, specify the HABP managementVLAN, and set the HABP request interval.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 modehabp server vlan vlan-id RequiredHABP works in client modeby default.Set the interval to sendHABP requestshabp timer interval Optional20 seconds by defaultConfiguring an HABP ClientConfigure the HABP client function on each device that is attached to the management device andneeds to be managed.
