Device management device and method

Abstract

The present invention provides a device management device and method, which are applied to member devices in a virtual network device. The member devices in the virtual network device include a primary member device and a plurality of standby member devices, and each member device is connected through cascading The cascading link connection between ports, the device performs the following processing flow: A. The main member device sends the first heartbeat message through its own cascading port, and sends the second heartbeat message through its own preset service port; B. . The standby member device directly cascaded with the primary member device receives the first and second heartbeat messages; C. When the standby member device does not receive the first and second heartbeat messages within a predetermined time , it is determined that the primary member device is in a failure state, and triggers reselection of the primary member device. The technical solution of the present invention effectively solves the problems in the prior art such as network faults caused by reselecting the primary member device when the primary member device operates normally.

Description

technical field [0001] The present invention relates to network technology, in particular to an equipment management device and method. Background technique [0002] At present, the virtualization management technology of network devices has been widely used in various networking environments. In the virtualization management technology, each member device needs to elect a master member device for management through a predetermined interaction mechanism. Other member devices are standby member devices for backup. Under normal circumstances, the primary member device can run well in the networking environment. However, when the cascaded physical link between the primary member device and the standby member device fails and is disconnected, how to deal with the fault has a great impact on the network. Normal operation has a big impact. [0003] In the prior art, each member device sends heartbeat messages to each other to detect whether other devices are online normally. Th...

Problems solved by technology

However, when the standby member device does not receive the heartbeat message, it may be that the physical link cascaded with the primary member device fails, while the primary member device is still running normally.

At this time, according to the existing technology, a new primary member device will be re-elected, and then two primary member devices will appear in the virtual device at the same time, and these two primary member devices will run as two independent entities on the existing In the networking environment, and the MAC addresses and configuration information of the two primary member devices are the same, this will lead to network confusion and even serious failures such as network service interruption.
