Problems solved by technology

In this networking, if the IRF link fails, one IRF will split into two new IRFs. These two IRFs have the same IP (Internet Protocol, Internet Protocol) and other three-layer configuration. If the two IRFs are Active (Active) state, which will cause address conflicts, which will cause faults to expand in the network

Abstract

The invention provides a stacking system split detection method and device. The method comprises the following steps: when a target parent device is a master device of a stacking system, sending an MAD detection message through a PEX port of a preset port expander, so that a PEX device receiving the MAD detection message forwards the MAD detection message to other PEX ports excluding an inlet port until the MAD detection message arrives at other parent devices in the stacking system, wherein the MAD detection message carries a domain identifier Domain ID and an activation identifier Active ID of the stacking system to which the target parent device belongs; and when the target parent device receives the MAD detection message, determining whether stacking system split happens according to the Domain ID and the Active ID carried in the MAD detection message. By adoption of the stacking system split detection method and device provided by the embodiment of the invention, the networking reliability can be improved.

Description

technical field [0001] The invention relates to the technical field of network communication, in particular to a stacking system split detection method and device. Background technique [0002] IRF3 (Intelligent Resilient Framework 3, the third generation intelligent elastic framework) is a vertical network integration virtualization technology developed to improve the access capability and management efficiency of the network access layer. Its core idea is to connect multiple PEX (Port Extender, port extender) devices to the parent device. After necessary configuration, each PEX device is virtualized into a remote interface board of the parent device, which is managed by the parent device. . Using this virtualization technology can increase the interface density of the parent device at a lower cost, simplify the network topology, and reduce network maintenance costs. [0003] In an actual IRF3 network, the parent device is usually an IRF composed of two or more devices. ...
