Embodiment Construction

[0023] The embodiment of the present invention is applicable to an LPU, and the LPU may refer to an LPU in a distributed switch system in which MPUs and LPUs are separated, or an LPU in a switch stack system. Such as figure 1 Shown is a schematic diagram of the relationship between two or more LPUs, where there are n LPUs, n is a natural number, and there is a control channel between every two LPUs, and any two LPUs can pass through The control channel implements data transmission. Among them, the LPU is used to judge whether the number of MAC addresses exceeds the limit, judge whether there is a MAC address obtained through active address learning on the LPU, delete part or all of the MAC addresses obtained through active address learning on the LPU according to preset rules, and The operation of deleting the MAC address is synchronized to each LPU except this LPU.

[0024] The embodiment of the present invention provides a MAC address management method, such as figure 2 ...

Abstract

The embodiment of the invention discloses a media access control (MAC) address management method and a line processing unit (LPU), relating to the field of communication technology, and aiming at solving the problems that the number of MAC addresses learned in a distributed system is inaccurate and exceeds the upper limit of user configurations, system congestion and other troubles are caused, and the user experience is affected. The method comprises the following steps: an LPU determines the number of target MAC addresses in the LPU, if the number of the target MAC addresses exceeds the limit, the LPU stops MAC address learning and deletes some or all of the MAC addresses obtained by active address learning, and the LPU synchronizes the operation of deleting the MAC addresses to each LPU other than the LPU. The scheme disclosed by the embodiment of the invention is suitable for the LPU.

Description

technical field [0001] Embodiments of the present invention relate to the field of communication technologies, and in particular to a distributed system Media Access Control (Media Access Control, MAC) address management method and a service board. Background technique [0002] In a distributed system, taking a distributed switch as an example, the hardware of the distributed switch may include a main control board (Micro Processing Unit, MPU) and multiple service boards (Line Processing Unit, LPU). Among them, there is a control channel between the MPU and the LPU, and there is also a control channel between any two LPUs. For any two LPUs, the communication between them can be realized through the control channel, for example, the MAC address can be learned through the control channel. [0003] Currently, MAC address learning can be divided into hardware learning and software learning. For example, hardware learning can be a process of utilizing a self-contained software ...
