example 1

[0052] see Figure 4 , Figure 4 Schematic diagram of the IRF split structure in Example 1.

[0053] exist Figure 4 Among them, four stacking devices constitute an IRF, where the device numbers of stacking device 1, stacking device 2, stacking device 3, and stacking device 4 are member ID 1, member ID2, member ID 3, and member ID 4, assuming that the current IRF The master device is stack device 1, and LACP MAD detection is enabled, and the IRF is interconnected with the uplink device through cross-chassis aggregation.

[0054] Such as Figure 4 In the IRF, when the stacking optical cable between stacking device 2 and stacking device 3 is interrupted, and the stacking optical cable between stacking device 1 and stacking device 4 is interrupted, the original IRF is split into two new stacking group IRFs, where The two member devices of stacking device 1 and stacking device 2 constitute a new stacking group IRF1, and the two member devices of stacking device 3 and stacking ...

Abstract

The invention discloses a multi-activation detection (MAD) method for an intelligent elastic framework (IRF), which comprises the steps of: receiving MAD messages at least containing an up-link bandwidth and being sent by other main devices by a main device; closing a service port of the device and service ports of the other devices of the IRF belonging to the device when any up-link bandwidth accepted by the main device is larger than the up-link bandwidth of the IRF belonging to the device; and maintaining the normal operation of the IRF belonging to the device when the up-link bandwidth accepted by the main device is smaller than the up-link bandwidth of the IRF belonging to the device. On the basis of the same invention concepts of the method, the invention also provides a device capable avoiding the breakdown status of all the services or most services of a stackable system.

Description

technical field [0001] The present invention relates to the field of communication technology, in particular to a multi-activation detection method and device for an intelligent elastic architecture. Background technique [0002] Intelligent Resilient Framework (IRF) is to connect multiple devices together through IRF ports to form a joint device; and users can manage all devices in the IRF by managing this joint device . It can be seen that by increasing the number of devices in the system, IRF can easily increase the number of ports, bandwidth, and packet processing capabilities of the system, that is, IRF can provide more stable multi-link backup through aggregation between multiple devices. Realize the high reliability of the link. [0003] When the stacking link of the IRF is disconnected, the original IRF will split into two or more IRFs with the same global configuration, and when the split IRFs with the same global configuration run in the network at the same time,...
