An out-of-band management realization method, a system for the same and an out-of-band management switch

Abstract

The invention provides an out-of-band management realization method, a system for the same and an out-of-band management switch. The realization method comprises the following steps: network management ports which are on the out-of-band management switch and which are connected with a control plate of a managed device form an aggregation port; the out-of-band management switch periodically sends out Link Aggregation Control Protocol (LACP) packets through each network management port of the aggregation port; the network management ports which receive within predetermined time LACP response packets replied by a main control plate of the managed device are set to active state; the network management ports which do not receive within predetermined time the LACP response packets are set to waiting state; and after the out-of-band management switch receives the control packets which are sent to the managed device from the network management server, the network management ports which are inactive state in the aggregation port will forward the control packets. The invention can, during the standby switch of the managed device, reduce the time length of the out-of-band management interruption and guarantee the HA performance of the out-of-band management.

Description

technical field [0001] The invention relates to the technical field of network communication, in particular to a method and system for realizing out-of-band management and an out-of-band management switch. Background technique [0002] Network management can be divided into two management modes: in-band management and out-of-band management. In-band management means that network management control information and service information are sent through the same logical channel. Information and service information are sent through different logical channels. Because the management control information in the out-of-band management mode is independent of the service network connection of the managed device, it can be used for emergency rescue of the managed device, so it is widely used in the fields of data center centralized management and branch network remote management. [0003] In addition, in fields such as centralized management of data centers, high reliability (HA) is re...

Problems solved by technology

Since this process requires manual intervention, it may cause a long-term interruption of out-of-band management, thereby reducing the HA performance of the entire data center

[0005] The above problems are more obvious when the core switch constitutes a stacking device. If multiple core switches constitute a stacking device, there may be two control boards in each core switch, but only one of the entire stacking device is used as the main control board. The control boards are all standby control boards. When the active / standby switchover occurs, the new active control board may be on other member devices in the stack device. At this time, it is necessary to manually connect the out-of-band management switch Migrating the control board of the control board to another member device will cause a long-term interruption of out-of-band management, thereby reducing the HA performance of the entire data center
