Problems solved by technology

When the configuration information is inconsistent, the security MAC synchronization may fail
For example, if the maximum number of MAC addresses on aggregated interface 2 of the master device is set to 100, and the maximum number of MAC addresses on aggregated interface 2 of the standby device is set to 200, the standby device will synchronize 200 secure MAC addresses with the master device, while the active The maximum MAC number of the device on aggregation interface 2 is 100, and there will be 100 security MAC synchronization failures

Abstract

Embodiments of the present application provide a method for synchronizing MAC addresses, a network device, and a computer-readable storage medium, and relate to the technical field of communications. The method is applied to the master device in the M-LAG, and the M-LAG also includes a backup device, and the method includes: receiving a negotiation request message sent by the backup device, the negotiation request message carrying all State the current configuration parameters of the standby device, determine the negotiated configuration parameters according to the received configuration parameters, local configuration parameters, and preset configuration parameter negotiation rules, store the negotiated configuration parameters, and send the negotiated configuration parameters to the standby device Sending a negotiation response message, where the negotiation response message carries the negotiated configuration parameters, so that the master device and the backup device perform MAC address synchronization processing according to the negotiated configuration parameters. The adoption of the application can ensure the consistency of configuration information and improve the success rate of synchronizing MAC addresses.

Description

technical field [0001] The present application relates to the field of communication technologies, and in particular to a method for synchronizing MAC addresses, network equipment and computer-readable storage media. Background technique [0002] Inter-device Link Aggregation Group (English: Multichassis Link Aggregation Group, referred to as: M-LAG) is a mechanism to achieve inter-device link aggregation. In M-LAG, technicians perform inter-device link aggregation on two devices. Thus, link reliability is improved from the board level to the device level. One of the devices is the master device, and the other device is the backup device. Wherein, the master device and the backup device are connected through an aggregation interface (may be referred to as aggregation interface 1). [0003] In a network where M-LAG is applied, network devices can be interconnected with aggregate interface 2 in the M-LAG environment through their pre-configured aggregation interface (may be ...
