Active hot start method, system and device for abnormal state of switch

Abstract

The invention provides an active hot start method, system and device for an abnormal state of a switch. The method comprises the following steps: configuring a redundancy protocol for the switch in a system environment; judging whether the load reference data of the current switch reaches a preset load threshold value or not, and if yes, recording a current system log and then actively triggering a hot start mechanism; executing, by the switch, a preset dynamic adjustment system log recording rule mechanism in the operation process. According to the invention, the system can still be ensured to run as expected when the switch is abnormal.

Description

technical field [0001] The present invention relates to the field of computer technology, and more specifically relates to an active hot start method, system and device for an abnormal state of a switch. Background technique [0002] At present, there must be a system log mechanism in the operating environment of the switch system. The recording logic of the system log is consistent regardless of whether the system state is relatively idle and stable, relatively tight, or even close to unloadable state. In addition, the current cold start and hot start mechanisms provided by the switch are all triggered by the operator, and the system itself does not provide a restart mechanism automatically triggered by the switch. [0003] In the existing technology, the system log recording logic used is inflexible. The purpose and scope of the information that the system needs to record when it is idle and in high operation state are fundamentally different. However, due to the lack of f...

In addition, the current cold start and hot start mechanisms provided by the switch are triggered by the operator, and the system itself does not provide a restart mechanism automatically triggered by the switch.

[0003] In the existing technology, the system log recording logic used is inflexible. The purpose and scope of the information that the system needs to record when it is idle and in high operation state are fundamentally different. However, due to the lack of flexible recording logic, maintenance personnel and function development When designing log information, the operator must make a trade-off between the readability and detail of the data, often resulting in the failure to find meaningful data from the system log to assist in identifying the problem when an abnormal situation occurs

[0004] Although the commonly used redundancy mechanism can ensure that the system environment can still operate normally in a certain degree of abnormal conditions, the redundancy mechanism itself has its own limit of abnormal states that can be tolerated. In the network field, when the device is disconnected (including undetectable or restart), the redundant backup mechanism will be triggered, but not every abnormal situation will cause the device to disconnect. not functioning properly

Furthermore, although some abnormal conditions will eventually lead to the restart of the device, the abnormal conditions of the device before the restart have cumulatively affected the operation of the connected devices or the operation of the entire system. Although the last device restarts, it can trigger redundant backup mechanism, but the number of abnormal devices in the entire system environment has reached an irreversible level
