Description
Technical Field
The present disclosure relates to communication technologies, and in particular, to a stacking apparatus and a stacking release method thereof.
Background
Virtualization technology is the focus of data center development attention, and is divided into two categories: one is N:1 virtualization in which a plurality of physical devices are integrated into one logical device, and the other is 1: N virtualization in which a plurality of logical networks isolated from each other are divided over one physical network or one physical device is divided into a plurality of virtual devices.
The IRF (Intelligent Resilient Framework, intelligent elastic framework) is formed by virtualizing a distributed device after IRF physical ports of a plurality of member devices are connected through IRF links, so that the cooperative work, unified management and uninterrupted maintenance of the plurality of devices are realized.
However, IRF link failure may cause one IRF system to split into multiple IRF systems having three layers of configuration, such as the same IP address, and may cause address collision, resulting in failure expanding in the network. Therefore, it is required to detect multiple IRFs existing in the network simultaneously through MAD (Multi-Active Detection) technology, and elect one IRF that continues to run, so as to reduce the influence of IRF splitting on the service. However, the MAD detection needs to occupy software processing resources of the device by sending standard protocol detection classifications through different protocol types, resulting in a longer intermediate state time of coexistence of IRF devices after unstacking, and being unable to rapidly unstacke, so that the IRF member devices after splitting are switched to corresponding operation states.
Disclosure of Invention
The invention provides a stacking device and a stacking release method thereof, which enable a member device after a split to be quickly switched to an operation state after the split of a stack, and quickly complete the stacking release.

To achieve the above object, the present application also provides a stacking apparatus, including: the memory is used for storing processor executable instructions; wherein the processor is configured to execute the following operations by executing processor-executable instructions in the memory: acquiring stacking port fault information; determining stacking release according to stacking port fault information; when the current state of each member device of the current logic device after the stack is released is obtained to be the activated state, obtaining the next-stage state of each member device of the current logic device; if the next-stage state of any member device of the current logic device is an active state, the current state of the device is kept to be the active state, and each service port of the device is kept to be in an open state.
The method has the advantages that after the stacking opening causes the stacking to be split, the stacking member equipment can be quickly switched to the state after the stacking is split according to the preset lower-stage state, and the stacking is quickly removed without being in the middle state of coexistence for a long time in the MAD detection process, so that the split IRF member equipment is switched to the corresponding running state.

S3 and S4 acquire that the current state of each member device of the current logic device after stacking is released is Active, and acquire that the next-stage state of each member device of the current logic device is Recovery, then set the current state of the device as Recovery, set each service port as closed state, and no longer execute message forwarding.
And then, S1-S4 respectively generate multi-activation detection messages and send the multi-activation detection messages through a detection link, the multi-activation detection messages sent by other stacking devices and received through the detection link are selected to form new logic devices as a stacking system to continue running, and the logic devices formed by S3 and S4 continuously keep respective service ports in a closed state to maintain a Recovery state.

The current states of S1-S3 are all Active; each member device synchronizes the setting information and forwarding information of the device to other member devices and operates as a logic device.
When the stack port between S1 and S2 fails first, S1 and S2 each determine that the stack system is split, S2 notifies S3 of the stack port failure message, S3 determines that the stack system is split into two stack systems, i.e., a new logical device constituted by S1, and another new logical device constituted by S2 and S3, and it is necessary to perform a stack release operation.
In fig. 3B, S1 obtains that the current state of the device in the current logical device after the stacking is released is Active, S1 obtains that the next-stage state of the device in the current logical device is Active, and S1 maintains the current state of the device as Active, and maintains each service port of the device as an open state.

S3, based on the same processing, the current state of the equipment is set to be Recovery, and each service port of the equipment is set to be in a closed state.
In fig. 2B, if the stacking port between S2 and S3 fails, S2 obtains that the current states of the device and S3 in the current logical device after the stacking is released are both Recovery, and no processing is required to keep the current state as Recovery.
In this embodiment, if S1 in fig. 3A is turned off due to power failure, S2 and S3 may set the respective states to the Recovery state according to the process in fig. 3B. S2 and S3 generate a multi-activation detection message and send the multi-activation detection message through a detection link; s2 and S3 only receive the multi-activation detection message sent by the other party, S2 and S3 form a new logic device to be selected as a new stacking system, S2 is selected as a main device, and the current state and the next-stage state of the device are updated to be Active; s3, selecting the slave equipment, updating the current state of the equipment into Active, and maintaining the next-stage state of the equipment to be Recovery.
