Embodiment Construction

[0049] The embodiment of the present invention proposes a MAD detection backup method, which is applied to an IRF network including multiple member devices. The Master device before the stack split) and at least one member device in the Slave state (that is, the Slave device before the stack split of the IRF network), and there is at least an IRF link between the member device in the Master state and the member device in the Slave state , the MAD detection link and the backup link corresponding to the MAD detection link.

[0050] For the convenience of description, in the embodiment of the present invention, a member device in the Master state and a member device in the Slave state are used as examples for illustration; based on this, the figure 1 It is a schematic diagram of the application scenario of the embodiment of the present invention. Device A is a member device in the Master state (that is, the Master device before the IRF network stack splits), and Device B is a mem...

Abstract

The invention discloses a multi-active detection (MAD) backup method and equipment. The method comprises the following steps: a member device monitors the condition of down or up of a port of an MAD link; when the port of the MAD link is down, the member device sends an MAD message to other member devices through a corresponding backup link of the MAD link; and when the port of the MAD link is up, the member device sends the MAD message to other member devices through the MAD link. According to the MAD backup method and equipment, when the fact that the port of the MAD link is down is monitored, MAD can be carried out through the backup link, so that a backup mechanism is provided for the MAD link, and the reliability of the MAD in an intelligent resilient framework (IRF) network.

Description

technical field [0001] The present invention relates to the field of communication technology, in particular to a MAD (Multi-Active Detection, multi-active detection) detection backup method and equipment. Background technique [0002] The core idea of ​​IRF (Intelligent Resilient Framework) is to connect multiple devices together and virtualize them into one device after necessary configuration. The use of IRF technology can integrate the hardware resources and software processing capabilities of multiple devices to achieve collaborative work, unified management and uninterrupted maintenance of multiple devices, improve device reliability, network expansion capabilities, and simplify device configuration and management. [0003] In an IRF network, multiple devices are connected to form an IRF network. The link that forms the IRF network is called an IRF link. IRF link failure will cause IRF to split, and when IRF splits, there will be two (or more) devices in the network wi...
