Configuring The Habp Server; Configuring An Habp Client - H3C S5120-SI Series Operation Manual

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 the HABP Server

Configuring an HABP Client

Configuring the HABP Server
You need to configure the management device as the HABP server, specify the HABP management
VLAN, and set the HABP request interval.
Follow these steps to configure an HABP server:
To do...
Enter system view
Enable HABP
Configure HABP to work in
server mode
Set the interval to send HABP
requests
Configuring an HABP Client
Configure the HABP client function on each device that is attached to the management device and
needs to be managed. As the HABP client function is enabled by default, this configuration task is
optional.
Follow these steps to configure an HABP client:
To do...
Enter system view
Enable HABP
Use the command...
system-view
habp enable
habp server vlan vlan-id
habp timer interval
Use the command...
system-view
habp enable
1-2
