Embodiment Construction

[0072] The basic idea of ​​the present invention is to create a MAD domain in the port of the opposite device, and the port in the MAD domain (belonging to the opposite device) maintains the same MAD information table; in the subsequent process, the member devices in the IRF periodically Send MAD information release messages randomly, and the port in the MAD field will compare whether the Active ID in the MAD information release message is the same with the ActiveID in the MAD information table stored in it. When the two are the same, the stack split can be determined. Then, the port can send the MAD information reflection message to the member device.

[0073] Since the MAD information reflection packet carries the number of UP physical ports of the member devices corresponding to other ports and the statistics of the total received traffic, when the member device receives the MAD information reflection packet, it can consider the UP physics of other member devices. The number o...

Abstract

The invention discloses an MAD testing method for an IRF stacker, comprising the following steps: establishing an MAD region by an opposite terminal device according to MAD information distribution messages; and judging whether stacking fission occurs or not according to the MAD information distribution messages, if so, sending the MAD information reflection messages to member devices by the opposite terminal device, and closing the own device ports or maintaining the own device ports to be in an Active state by the member devices according to the MAD information reflection messages. In the invention, the MAD testing process is more efficient and the application range is not limited by networking.

Description

Technical field [0001] The present invention relates to the field of communication technology, and in particular to a MAD detection method and device for IRF stacking equipment. Background technique [0002] IRF (Intelligent Resilient Framework) is to connect multiple devices through IRF ports to form a joint device; and users can manage all devices in the IRF by managing this joint device. management. It can be seen that by increasing the number of devices inside the system, IRF can easily increase the number of ports, bandwidth, and message processing capabilities of the system. That is, IRF can provide more stable multi-link backup through the aggregation of multiple devices. Achieve high reliability of the link. [0003] When the stack link of the IRF is disconnected, the original IRF will be split into two (or more) IRFs with the same global configuration. When the split into the IRF with the same global configuration runs on the network at the same time, it may cause the ne...
