Method and device for establishing a detection path

Abstract

The present invention provides a detection path establishment method and device, wherein the detection path establishment method applied to the active parent device of the vertical stacking system includes: generating a notification message for triggering the detection path establishment according to the detection path establishment cycle; wherein, the notification message The source MAC address of the message is the active parent device, and the destination MAC address of the notification message is the target parent device; identify the path to the target parent device according to the topology of the vertical stacking system; select a path from the identified paths according to the priority of the detection path ;Send a notification message through the PEX physical port on the selected path; determine that the PEX physical port receives the response message within the notification detection path establishment period; establish a detection message forwarding table entry that the outgoing port is a PEX physical port to establish a detection path.

Description

technical field [0001] The present invention relates to communication technology, in particular to a vertical stacking system split detection technology, specifically a method and device for establishing a detection path. 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] exist figure 1 In the shown IRF3 netwo...

AI Technical Summary

Problems solved by technology

When the stacking link between two parent devices fails, it will cause one IRF to split into two new IRFs. These two IRFs have the same IP (Internet Protocol, Internet Protocol) and other three-layer configuration. All are in the Active (activated) state, which will cause address conflicts and cause faults to expand in the network
