A configuration error detection method, device and system for forwarding equipment in a backup plane

Abstract

The embodiment of the present invention discloses a configuration error detection method, device and system for forwarding equipment in a backup plane. In a network with a main plane and a backup plane, the corresponding test equipment is determined from the main plane for the equipment to be detected. A routing protocol processing instance in the sandbox system is set in each device to be tested and the test device, and a connection between the sandbox systems is established, and the fault type of the sandbox system in the first device is set according to the test task. Through simulation In the failure environment of the second device, switch the routing protocol processing instance in the sandbox system of the second device to be the active device, so as to detect whether the second device has a configuration error. On the premise that the network normally uses the main plane to provide services, the sandbox system simulates the failure environment to detect the business processing situation when the forwarding device in the backup plane is switched to the active device, and can effectively find out whether the forwarding device in the backup plane has configuration errors. Therefore, the stability of the forwarding device in the standby plane is improved.

Description

technical field [0001] The invention relates to the communication field, in particular to a configuration error detection method, device and system for forwarding equipment in a backup plane. Background technique [0002] In a network, such as an IP network, it is very important to avoid service interruption. When a forwarding device or a link between forwarding devices fails, it is necessary to quickly re-determine the replacement of the forwarding device and continue to provide the services processed by the forwarding device. other forwarding devices. For this reason, the forwarding device can be divided into active and standby to form a main plane and a backup plane. The forwarding device in the main plane is used as the main device of the network to provide normal functions and business processing that can be realized for the network. The forwarding device in the main plane serves as the backup device for the forwarding device in the main plane. When the forwarding dev...

AI Technical Summary

Problems solved by technology

[0004] If there is an error in the configuration of the forwarding device in the current main plane, the service of the forwarding device will not be opened, so the configuration error of the forwarding device in the main plane is easy to be found

However, the forwarding devices on the standby plane do not usually handle substantive services, but generally configuration errors can only be discovered when processing services. It will handle substantive business, so even if there is a configuration error in the forwarding device in the backup plane, it is difficult to be discovered in advance, or in other words, it is difficult to find out before being switched to the active device

[0005] In this way, when the forwarding device in the main plane fails and needs to be replaced by the forwarding device in the standby plane to continue processing services, if the replacement forwarding device has configuration errors, it will soon fail when processing services. The backup device is then configured with the backup device, so when the backup device fails after the active / standby switchover, it may cause business interruption or even cause a major accident
