The invention provides an aggregation link recovery method and an apparatus. The method is applied to main equipment in an aggregation group and includes: obtaining an aggregation link recovery message; making aggregation selection according to the aggregation link recovery message; obtaining aggregation activity members after aggregation selection, starting a first timer corresponding to a preset first time value, and sending a backup message with the aggregation activity members and the first system time to slave equipment; and sending the aggregation activity members to a data plane of the main equipment when the first timer reaches the preset first time value. According to the method and the apparatus, the synchronization of system time of the main equipment and the slave equipment can be guaranteed, the errors are small, the convergence speed of aggregation link recovery can be accelerated, the convergence time of aggregation link recovery is greatly shortened, and the convergence time is very stable.
Description
technical field [0001] The present invention relates to the technical field of network communication, in particular to a method and device for recovering aggregated links. Background technique [0002] Port aggregation aggregates multiple physical Ethernet ports together to form a logical aggregation group, which can realize traffic sharing among member ports in the aggregation group to increase bandwidth. In a device stacking environment, using the port aggregation method can ensure that services can continue to be forwarded after a failure of one of the virtualized devices, thus avoiding long-term interruption of services and achieving high-reliability networking guarantees. [0003] In the prior art, the stacking device is aggregated with the downstream device, and the network traffic will be distributed to the stacking device. The master device in the stacking device completes the operation of the control plane, and the slave device in the stacking device shares the traf...
