3.1 Introduction to HABP

With 802.1x enabled, a switch authenticates and then authorizes 802.1x-enabled ports.
Packets can be forwarded only by authorized ports. For ports with switches attached
and are not authenticated and authorized by 802.1x, their received packets will be
filtered. This means that you cannot manage the attached switches. Huawei
authentication bypass protocol (HABP) is designed to address this problem.
An HABP packet carries the MAC addresses of the attached switches with it. It can
bypass the 802.1x authentications when traveling between HABP-enabled switches,
through which management devices can obtain the MAC addresses of the attached
switches and thus the management of the attached switches is feasible.
HABP is implemented by HABP server and HABP client. Normally, an HABP server
sends HABP request packets regularly to HABP clients to collect the MAC addresses of
the attached switches. HABP clients respond to the HABP request packets and forward
the HABP request packets to lower-level switches. HABP servers usually reside on
management devices and HABP clients usually on attached switches.
For ease of switch management, it is recommended that you enable HABP for
802.1x-enabled switches.

3.2 HABP Server Configuration

With the HABP server launched, a management device sends HABP request packets
regularly to the attached switches to collect their MAC addresses. You need also to
configure the interval on the management device for an HABP server to send HABP
request packets.
