Embodiment Construction

[0015] figure 2 It is a schematic structural diagram of a network device, including at least two line cards, a controller, and a backplane. Wherein, the controller can be separately arranged on a printed circuit board, and can also be integrated in any line card. Alternatively, controllers are integrated inside the two line cards, and the two controllers cooperate to implement the control function. Both the controller and the line cards are connected to the backplane.

[0016] figure 2 The network devices shown can be figure 1 The router shown in , or the network switch that implements the OAM function.

[0017] image 3 shown as figure 2 The process of performing OAM handover by the shown network equipment includes the following steps:

[0018] S301: The controller in the network device installs OAM instance 1 on any line card (denoted as line card 1) in the network device. OAM instance 1 has OAM parameter 1, and sends it to the detected link according to OAM parame...

Abstract

An OAM switching method is applied to network equipment. The first line card in the network device is installed with the first OAM instance, the second line card runs the second OAM instance, the second line card sends the first OAM message according to the OAM parameters, and the first line card is disabled to send the OAM message. The first line card judges whether it has received the heartbeat message sent by the second line card in the network device. If the first line card does not receive the heartbeat message sent by the second line card, the first line card sends the second OAM message according to the OAM parameters. arts. Because the line card cannot send heartbeat packets when a fault occurs, the first line card can detect the fault of the second line card and send an OAM packet to the link detected by the second OAM instance, so that the network device can communicate with the In the case of link communication, avoid link switchover caused by line card failure.

Description

technical field [0001] The present application relates to the communication field, and in particular to an operation and management (English: operation and management, OAM) handover method and network equipment. Background technique [0002] In order to ensure the normal transmission of data, the communication system usually adopts the mechanism of active and standby links. Such as figure 1 As shown, router 1 and router 2 on the main link transmit OAM packets to each other, and if router 1 or router 2 cannot receive the OAM packets sent by the peer end, it is determined that the link is faulty. After a link fails, the communication system performs link switching, that is, the standby link communication is enabled. [0003] Even if the link does not fail, if the internal line card of the router installed on the link fails, the line card of the router connected to the router by this link cannot receive the OAM message. Therefore, a line card failure will also trigger a link...
