Figure 1-1 Network diagram for HABP application

HABP 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 above

example), and the attached switches function as the HABP clients, such as Switch B through Switch E

in 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, and

the clients respond to the requests. After the server 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 ports of the server without affecting the normal operation of

the 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 the

management VLAN.

Configuring HABP

Complete the following tasks to configure HABP:

Configuring an HABP Client

Configuring the HABP Server

With the HABP server function enabled, the administrative device starts to send HABP requests to the

attached switches. The HABP responses include the MAC addresses of the attached switches. This

makes it possible for the administrative device to manage the attached switches.

You can configure the interval of sending HABP requests on the administrative device.

Follow these steps to configure an HABP server:
