A method performed by a first network device comprises reaching a synchronization state with a first communication device based on alignment information of a first interface of the first network device. The alignment information of the first interface includes at least one of a line rate order for line rate iteration, an iteration time interval and an iteration start time. The method further comprises determining whether a second network device has reached the synchronization state with a second communication device at a same line rate as the first interface, wherein the second network device includes a second interface, and the second network device tries to reach the synchronization state with the second communication device based on the same alignment information as the first interface of the first network device. The method further comprises locking the same line rate at the first interface of the first network device.
