Embodiment 1

[0025] refer to figure 2 , shows a flow chart of steps of a link fault handling method according to Embodiment 1 of the present application.

[0026] This embodiment describes the IRF link fault handling from the IRF stack member device side.

[0027] The link failure handling method in this embodiment is used for link failure handling between IRF stack member devices, and includes the following steps:

[0028] Step S102: When the link between the stack member devices of the IRF fails, the IRF splits, and some of the stack member devices of the IRF determine that they need to enter the disabled state, that is, the Recovery state.

[0029] As mentioned above, after an IRF is split, the IRF with the smallest master member number will continue to work normally, while other IRF member devices need to migrate to the recovery state (that is, the disabled state).

[0030] Step S104: The stack member devices that need to be turned into the disabled state send notification messages ...

Embodiment 2

[0040] refer to image 3 , shows a flow chart of steps of a link fault handling method according to Embodiment 2 of the present application.

[0041] This embodiment describes the IRF link fault handling from the upstream and downstream device sides of the IRF stack member devices.

[0042] The link failure handling method in this embodiment is used for link failure handling between IRF stack member devices, and includes the following steps:

[0043] Step S202: The upstream and downstream devices of the IRF stack member device receive the notification message sent by the IRF stack member device.

[0044] An IRF stack member device that needs to be turned into a disabled state will send a notification message to its upstream and downstream devices to notify its upstream and downstream devices that they will no longer send service data to it, but can receive the service data sent by it.

[0045] Step S204: The upstream and downstream devices of the IRF stack member device set ...

Embodiment 3

[0055] refer to Figure 4 , shows a flow chart of steps of a link fault handling method according to Embodiment 3 of the present application.

[0056] In this embodiment, the IRF link fault handling is described from the perspective of data interaction between an IRF stack member device and its upstream and downstream devices.

[0057] The link fault processing method in this embodiment includes the following steps:

[0058] Step S302: The IRF stack member device determines that it needs to enter the disabled state.

[0059] The IRF stack member devices in this embodiment refer to the IRF stack member devices that need to be turned into a disabled state after a link failure.

[0060] Step S304: The IRF stack member device sends a notification message to its upstream and downstream devices. At the same time, the IRF stack member device keeps the hardware forwarding table entry unchanged, and sends the remaining business data.

[0061] Preferably, the notification message in...

Abstract

The invention provides a link failure processing method, an intelligent resilient framework (IRF) member device and a data communication device. The link failure processing method includes: when a stack member device of an IRF is determined to be in a forbidden state, the stack member device transmits informing massages to upstream and downstream devices to enable the upstream and downstream devices to be in informing states, and then business data can be prevented from being transmitted to the stack member device, wherein the informing state shows that the upstream and downstream devices receive business data transmitted by the stack member device but not transmit the business data to the stack member device; simultaneously, the stack member device keeps hardware forwarding table items to be invariable, transmits the remaining business data on the stack member device to the upstream and downstream devices according to the hardware forwarding table items and turns into the forbidden state when all the remaining business data are determined to be forwarded. By means of the link failure processing method, the IRF member device and the data communication device, the phenomenon of package loss when the IRF stack member device is in the forbidden state is avoided.

Description

technical field [0001] The present application relates to the field of communication technologies, and in particular to a method for processing link failures between member devices of an IRF (Intelligent Resilient Framework, intelligent resilient framework), an IRF member device and a data communication device. Background technique [0002] The core idea of ​​IRF is to connect multiple devices together through IRF physical ports, and after necessary configuration, virtualize them into a "distributed device". Using this virtualization technology, you can gather the hardware resources and software processing of multiple devices. Ability to realize the collaborative work and unified management of multiple devices, and improve the utilization and efficiency of devices. figure 1 is a schematic diagram of IRF, such as figure 1 As shown in the figure, two devices, Device A (Device A) and Device B (Device B), are stacked to form an IRF system. Device A and Device B are member devic...
