Example Embodiment

[0025] Hereinafter, the present invention will be further described in detail through specific embodiments in conjunction with the drawings.

[0026] See figure 1 As shown, the communication equipment in this embodiment includes a line card, a main main control board, and a standby main control board; it is worth noting that the main main control board and the standby main control board in this embodiment are opposite. That is, at a certain moment, when a certain main control board is the active main control board, after the main-standby switchover, the main control board will be switched to the standby main control board, and the original standby main control board is switched to Main control board. The line card in this embodiment is connected to the main main control board and the standby main control board through two ports respectively; the ports in this embodiment can be SERDES interface or SGMII interface or SMII interface or XAUI interface or RXAUI interface or KR interfa...

Abstract

Provided are a communication device and active/standby switchover method thereof, the communication device comprising a line card, an active main control board, and a standby main control board. The line card is connected to the active main control board and the standby main control board respectively via two ports; the line card comprises a switchover detection module and a switchover processing module; the switchover detection module is configured to detect whether an active/standby switchover is triggered, and transmit a switchover notification to the switchover processing module upon the detection of the trigger of the active/standby switchover; the switchover processing module is configured to add, during initialization, the port connecting the line card to the active main control board into a specified logical port group, such that the source port of an MAC address learned by the downlink data on the line card is the logical port group; and the switchover processing module is configured to delete the port connecting the line card to the active main control board from the logical port group upon receipt of the switchover notification, and add the port connecting the line card to the standby main control board into the logical port group. The present invention greatly improves user satisfaction for service experience.

Description

technical field [0001] The invention relates to the communication field, in particular to a communication device and an active / standby switching method thereof. Background technique [0002] Communication equipment (such as OLT in optical access equipment) is generally composed of chassis, backup board, power card, main control board, line card, and uplink board. The task of the main control board is business exchange, Convergence and centralized control, while the line card is responsible for the realization of specific business requirements or functions. [0003] In order to improve the reliability of communication equipment, the main control board often adopts the active and standby mechanism. In the active / standby mechanism, there are usually two main control boards, one is the active main control board, and the other is the standby main control board. When the active main control board fails, service control and service forwarding are switched to the standby main contr...
