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.

Embodiment 1

[0025] Embodiment 1: Perform out-of-band management on a core switch equipped with two control boards.

[0026] There are two control boards in the core switch: control board A and control board B. The network management connection ports connecting the out-of-band management switch to control board A and control board B are port 1 and port 2 respectively, and port 1 and port 2 form a Aggregated ports, that is, aggregated into one logical port, make the connection between the out-of-band management switch and the core switch externally appear as one connection, thereby minimizing the scope of the out-of-band management broadcast domain.

[0027] The pre-configured out-of-band management address of the core switch is IPm, and the out-of-band management address is associated with the aggregation port formed by port 1 and port 2. Enable the LACP protocol on port 1 and port 2 respectively, and enable the LACP protocol on the ports connected to port 1 and port 2 on the core switch. ...

Embodiment 2

[0035] Embodiment 2: Perform out-of-band management on a stack device with multiple member devices.

[0036] Member device 1, member device 2, and member device 3 form a stack device. Each member device has two control boards, namely control board A1, control board B1, control board A2, control board B2, control board A3 and Control board B3, the network management connection ports connected to the out-of-band management switch and these control boards are port 1, port 2, port 3, port 4, port 5 and port 6, port 1, port 2, port 3, port 4, port Port 5 and port 6 form an aggregation port, so that the connection between the out-of-band management switch and the stacking device appears as one connection to the outside, thereby minimizing the scope of the out-of-band management broadcast domain.

[0037] The out-of-band management address of the pre-configured stacking device is IPn, and the out-of-band management address is associated with the aggregation port formed by port 1, por...

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...
