Method and apparatus for stacking member port detection

Abstract

The invention discloses a method and a device for detecting stack member port. The method comprises the following steps: transmitting a first initial detection message to the message port of opposite member equipment connected with the local member port when the state of the local member port changes from down to up; receiving the response of the member port of the opposite member equipment to the first initial detection message; and determining the configuration validity of the local member port and switching the state of the local member port according to the response of the member port of the opposite member equipment. In the invention, when the member port of a stack port changes from down to up, the first initial detection message is transmitted to the member port of the opposite member equipment connected with the local member port firstly, and the configuration validity of the local member port is detected according to the response of the member port of the opposite member equipment so as to switch the local member port to up when the local member port has valid configuration, thereby ensuring correct use of the stack port.

Description

Technical field [0001] The present invention relates to the field of communications, and in particular to a method and device for detecting stack member ports. Background technique [0002] Stack usually refers to a management domain composed of some Ethernet switches connected through stacking ports. Multiple Ethernet switches stacked together can be used as one device, and users can use one of the switches to realize stacking. Management of all switches within. [0003] IRF (Intelligent Resilient Framework) is a technology that stacks multiple devices to virtualize one device for management and use. Such as figure 1 As shown, the user realizes the management of all devices in the stack through the management of virtual devices in the IRF stack. The devices that make up the stack in the IRF stack are called member devices, and member devices can be divided into Master devices and Slave devices according to their different functions. Among them, the master device is responsible ...

AI Technical Summary

Problems solved by technology

[0007] The problem in the prior art is: in the case of multiple member ports, the member device only uses the main port to send a message to the peer member device to check whether the configuration of the stack port is correct, and the ports other than the master port and the peer member Whether the connection of the device is correct is no longer detected, so the validity of other ports other than the main port in the stack port cannot be detected

At the same time, if the detection of the member port is incorrect, it will be judged that the configuration of the entire stack port is wrong, which obviously cannot meet the requirements compared with the need for carrier-level reliability in the communication field
