Description

Dynamic configuration method for internal control link port and related device

Technical Field

The invention relates to the technical field of distributed link aggregation, in particular to a dynamic configuration method and a related device for an internal control link port.

Background

In a Distributed Resilient Network Interconnect (DRNI) typical networking System, a plurality of Network forwarding devices are aggregated by ethernet links to form a Distributed aggregation System (DR), and on the Network, the DR System appears as one Network forwarding device to the outside. Network forwarding devices forming the DR system are called Distributed Relay devices (DR devices), and real-time synchronous data is aggregated among a plurality of DR devices through ethernet links, so that cross-device link aggregation is realized, and device-level redundancy protection is provided. Each DR device includes a Distributed Relay interface (DR interface) and an internal control link Port (IPP), and when the DR interface and the IPP Port on each DR device are not consistent with each other in terms of a Virtual Local Area Network (VLAN) allowed to pass, if the DR interface is abnormal, the IPP Port of the DR device to which the abnormal DR interface belongs cannot normally forward the traffic of the DR interface, which finally causes service interruption, thereby reducing the reliability of the DR system. When the allowed VLANs set on the DR interfaces of the two DR devices in the DR system are not consistent or the allowed VLANs set on the IPP ports of the two DR devices are not consistent, if a link between one of the DR devices and a network forwarding device outside the DR system fails, the other DR device cannot normally take over the traffic forwarding task of the DR device, which finally causes service interruption and reduces the reliability of the DR system.

First embodiment

Referring to fig. 3, fig. 3 is a flowchart illustrating a dynamic configuration method for an internal control link port applied to a distributed aggregation system according to an embodiment of the present invention. The processing method comprises the following steps:

step S101, the first distributed aggregation device receives a second list sent by the second distributed aggregation device.

In the embodiment of the present invention, the first distributed aggregation device 100 and the second distributed aggregation device 300 are communicatively connected and together form a distributed aggregation system, and the second distributed aggregation device 300 includes the distributed aggregation interface 104. The second list is a virtual local area network that is pre-stored in the second distributed aggregation device 300 and includes the virtual local area network that is pre-configured by the user and allowed to pass through the distributed aggregation interface 104 of the second distributed aggregation device 300, that is, traffic from the virtual local area network in the second list may be forwarded to the external device 400 through the distributed aggregation interface 104 of the second distributed aggregation device 300, or traffic from the virtual local area network in the second list that is sent by the external device 400 may be received and forwarded through the distributed aggregation interface 104 of the second distributed aggregation device 300.

It should be noted that the number of the distributed aggregation interfaces 104 included in the second distributed aggregation device 300 may be multiple, in this case, each distributed aggregation interface 104 of the second distributed aggregation device 300 corresponds to one second list, and therefore, the number of the second lists received by the first distributed aggregation device 100 and sent by the second distributed aggregation device 300 is also multiple. The distributed aggregation interface 104 of each second distributed aggregation device 300 may be configured with a plurality of virtual local area networks that are allowed to pass through the distributed aggregation interface 104, and therefore, there are a plurality of virtual local area networks in the second list corresponding to the distributed aggregation interface 104 of each second distributed aggregation device 300, for example, the second distributed aggregation device 300 includes 2 distributed aggregation interfaces 104: the number 1 distributed aggregation interface 104 and the number 2 distributed aggregation interface 104, the allowed virtual local area networks configured by the number 1 distributed aggregation interface 104 are virtual

local area networks

1, 2, and 3, and the allowed virtual local area networks configured by the number 2 distributed aggregation interface 104 are virtual

local area networks

1, 3, and 5, and then the virtual local area networks included in the second list corresponding to the number 1 distributed aggregation interface 104 of the second distributed aggregation device 300 are: virtual

local area networks

1, 2, and 3, and the virtual local area networks included in the second list of the second distributed aggregation device 300 corresponding to the number 2 distributed aggregation interface 104 are: virtual local area network 1, virtual local area network 3, virtual local area network 5.

Step S102, the first distributed aggregation device determines a virtual local area network to be loaded according to the second list and the first list.

In this embodiment of the present invention, the first list is a virtual local area network that is pre-stored in the first distributed aggregation device 100 and includes a virtual local area network that is pre-configured by a user and allows the distributed aggregation interface 104 of the first distributed aggregation device 100 to pass through. The implementation manner of determining the to-be-loaded virtual local area network according to the second list and the first list may be: the first distributed aggregation device 100 determines the virtual local area networks existing in the second list and the first list at the same time as the virtual local area networks to be loaded, for example, the first list includes virtual local area network 1, virtual local area network 2, and virtual local area network 3, the second list includes virtual local area network 1, virtual local area network 3, and virtual local area network 5, and the virtual local area networks existing in the second list and the first list at the same time are virtual local area network 1 and virtual local area network 3, and thus, virtual local area network 1 and virtual local area network 3 are the virtual local area networks to be loaded. The way of determining the to-be-loaded vlan may be to mark the vlans existing in the second list and the first list at the same time, for example, mark the vlans existing in the second list and the first list at the same time as active, mark the vlans not existing in the second list and the first list at the same time as inactive, and forward the traffic from the vlan marked as active through the distributed aggregation interface 104 of the first distributed aggregation device 100, but not forward the traffic of the vlan marked as inactive through the distributed aggregation interface 104 of the first distributed aggregation device 100.

It should be noted that the number of the distributed aggregation interfaces 104 included in the first distributed aggregation device 100 may be multiple, and each distributed aggregation interface 104 of the first distributed aggregation device 100 corresponds to one first list, so that the number of the first lists on the first distributed aggregation device 100 is multiple. In a case that the first distributed aggregation device 100 includes a plurality of distributed aggregation interfaces 104 or the second distributed aggregation device 300 also includes a plurality of distributed aggregation interfaces 104, the distributed aggregation interfaces 104 of the first distributed aggregation device 100 and the distributed aggregation interfaces 104 of the second distributed aggregation device 300 that are connected to the same external device 400 are divided into the same distributed aggregation group, and the relevant configurations of the distributed aggregation interfaces 104 of the same distributed aggregation group must be the same, for example, the working mode, the number, and the like, at this time, the implementation method for determining, by the first distributed aggregation device 100, the virtual local area network to be loaded according to the second list and the first list may be: according to the first list corresponding to the distributed aggregation interface 104 of the first distributed aggregation device 100 and the second list corresponding to the distributed aggregation interface 104 of the second distributed aggregation device 300 in each distributed aggregation group, determining the virtual local area network to be loaded corresponding to the distributed aggregation interface 104 of the first distributed aggregation device 100 belonging to the distributed aggregation group. For example, the first distributed aggregation device 100 includes 2 distributed aggregation interfaces 104: the distributed aggregation interface 1 and the distributed aggregation interface 2 104 include, in a first list corresponding to the distributed aggregation interface 1, virtual local area networks 1 and virtual machine local area networks 2, and in a first list corresponding to the distributed aggregation interface 2, virtual local area networks 2 and virtual machine local area networks 3, the second distributed aggregation device 300 includes 2 distributed aggregation interfaces 104: a number 3 distributed aggregation interface 104 and a number 4 distributed aggregation interface 104, the second list corresponding to the number 3 distributed aggregation interface 104 includes virtual local area networks 2 and 3 virtual machine local area networks, the first list corresponding to the number 4 distributed aggregation interface 104 includes virtual local area networks 3 and 4 virtual machine local area networks, the number 1 distributed aggregation interface 104 and the number 3 distributed aggregation interface 104 are connected to the same number 1 external device 400, and the number 2 distributed aggregation interface 104 and the number 4 distributed aggregation interface 104 are connected to the same number 2 external device 400, so that the number 1 distributed aggregation interface 104 and the number 3 distributed aggregation interface 104 belong to the number 1 distributed aggregation group, the number 2 distributed aggregation interface 104 and the number 4 distributed aggregation interface 104 belong to the number 2 distributed aggregation group, and virtual local area networks existing in the first list corresponding to the number 1 distributed aggregation interface 104 and the second list corresponding to the number 3 distributed aggregation interface 104 at the same time, that is, the virtual local area network 2 is determined as the virtual local area network to be loaded corresponding to the distributed aggregation interface No. 1 of the first distributed aggregation device 100, and the virtual local area networks that exist in the first list corresponding to the distributed aggregation interface No. 2 104 and the second list corresponding to the distributed aggregation interface No. 4 at the same time, that is, the virtual local area network 3 is determined as the virtual local area network to be loaded corresponding to the distributed aggregation interface No. 2 of the first distributed aggregation device 100.

Step S103, the first distributed aggregation device loads the virtual local area network to be loaded to the internal control link port of the first distributed aggregation device.

In the embodiment of the present invention, since the to-be-loaded virtual local area network is a virtual local area network that allows the distributed aggregation interface 104 of the first distributed aggregation device 100 to load the to-be-loaded virtual local area network into the internal control link port 105 of the first distributed aggregation device 100, the to-be-loaded virtual local area network also allows the internal control link port 105 of the first distributed aggregation device 100, that is, the to-be-loaded virtual local area network may pass through both the distributed aggregation interface 104 of the first distributed aggregation device 100 and the internal control link port 105 of the first distributed aggregation device 100, when the traffic from the to-be-loaded virtual local area network cannot be forwarded normally due to an abnormality of the distributed aggregation interface 104 of the first distributed aggregation device 100, the traffic may be forwarded through the internal control link port 105 of the first distributed aggregation device 100, the service is ensured not to be interrupted, and the reliability of the distributed aggregation system is improved.

In the embodiment of the present invention, loading the to-be-loaded virtual local area network to the internal control link port 105 of the first distributed aggregation device 100 is implemented in a dynamic manner, and certainly, may also be implemented in a static manner, that is, manually configuring the internal control link port 105 of the first distributed aggregation device 100, and allowing the to-be-loaded virtual local area network to pass through the internal control link port 105 of the first distributed aggregation device 100. The dynamic implementation is more efficient than the static implementation, and is less prone to errors, when the virtual local area network allowed by the distributed aggregation interface 104 of the first distributed aggregation device 100 changes, the internal control link port 105 of the corresponding first distributed aggregation device 100 may be automatically changed accordingly, and it is ensured that the distributed aggregation interface 104 of the first distributed aggregation device 100 and the virtual local area network allowed by the internal control link port 105 of the corresponding first distributed aggregation device 100 are consistent in real time.

In this embodiment of the present invention, in order to ensure that a virtual machine local area network that can pass through the distributed aggregation interface 104 of the first distributed aggregation device 100 and the internal control link port 105 of the first distributed aggregation device 100 is consistent with a virtual machine local area network that can pass through the distributed aggregation interface 104 of the second distributed aggregation device 300 and the internal control link port 105 of the second distributed aggregation device 300, where the distributed aggregation interface 104 of the first distributed aggregation device 100 and the distributed aggregation interface 104 of the second distributed aggregation device 300 both belong to one distributed aggregation group, the second distributed aggregation device 300 is further required to determine a virtual local area network to be loaded according to the first list and the second list, and load the virtual local area network to be loaded to the internal control link port 105 of the second distributed aggregation device 300. Therefore, the embodiment of the present invention further includes steps S104 to S106, and the implementation method of steps S104 to S106 is similar to that of steps S101 to S103, and is not described herein again.

Step S104, the second distributed aggregation device receives the first list sent by the first distributed aggregation device.

Step S105, the second distributed aggregation device determines the virtual local area network to be loaded according to the first list and the second list.

Step S106, the second distributed aggregation device loads the to-be-loaded virtual local area network to the internal control link port of the second distributed aggregation device.

It should be noted that steps S101 to S103 executed by the first distributed aggregation device 100 may be performed simultaneously with steps S104 to S106 executed by the second distributed aggregation device 300, and it is not necessary that the first distributed aggregation device 100 first performs steps S101 to S103, then the second distributed aggregation device 300 performs steps S104 to S106, nor that the second distributed aggregation device 300 first performs steps S104 to S106, then the first distributed aggregation device 100 performs steps S101 to S103.

In this embodiment of the present invention, after the first distributed aggregation device 100 performs steps S101 to S103 and the second distributed aggregation device 300 performs steps S104 to S106, the virtual machine local area network that can pass through the distributed aggregation interface 104 of the first distributed aggregation device 100 and the internal control link port 105 of the first distributed aggregation device 100 may also pass through the distributed aggregation interface 104 of the second distributed aggregation device 300 and the internal control link of the second distributed aggregation device 300, and when a link between the first distributed aggregation device 100 and the external device 400 is abnormal and traffic of the virtual local area network cannot be forwarded through the first distributed aggregation device 100, the traffic of the virtual local area network may be sent to the second distributed aggregation device 300 and forwarded to the external device 400 by the second distributed aggregation device 300.

In the embodiment of the present invention, the virtual local area networks that allow the distributed aggregation interface 104 of the first distributed aggregation device 100 and the internal control link port 105 of the first distributed aggregation device 100 to be maintained as consistent in a dynamic manner, and the virtual machine local area networks that may pass through the distributed aggregation interface 104 of the first distributed aggregation device 100 and the internal control link port 105 of the first distributed aggregation device 100 and the virtual machine local area networks that may pass through the distributed aggregation interface 104 of the second distributed aggregation device 300 and the internal control link port 105 of the second distributed aggregation device 300 are maintained as consistent, which has the following advantages compared with the prior art:

first, the dynamic implementation reduces the workload of manual setting and avoids the problem that manual setting is prone to errors.

Secondly, the dynamic implementation automatically implements that, as the distributed aggregation interface 104 of the first distributed aggregation device 100 allows passing through the change of the virtual local area network or the distributed aggregation interface 104 of the second distributed aggregation device 300 allows passing through the change of the virtual local area network, the internal control link port 105 of the first distributed aggregation device 100 or the internal control link port 105 of the second distributed aggregation device 300 is changed accordingly, thereby enabling the virtual local area networks that the first distributed aggregation device 100 and the second distributed aggregation device 300 can forward to be consistent in real time, when the distributed aggregation interface 104 of the first distributed aggregation device 100 or the distributed aggregation interface 104 of the second distributed aggregation device 300 is abnormal, or the link between the first distributed aggregation device 100 and the external device 400 is abnormal, or the link between the second distributed aggregation device 300 and the external device 400 is abnormal, the normal operation of the service is not affected, so that the reliability of the distributed aggregation system is improved.

Thirdly, the virtual local area networks allowed to pass through by the distributed aggregation interfaces 104 of the first distributed aggregation device 100 and the distributed aggregation interfaces 104 of the second distributed aggregation device 300 are set as the virtual local area networks allowed to pass through by the internal control link ports 105 of the first distributed aggregation device 100 and the internal control link ports 105 of the second distributed aggregation device 300, and the internal control link ports 105 of the first distributed aggregation device 100 and the internal control link ports 105 of the second distributed aggregation device 300 are not set as the virtual local area networks allowed to pass through, so that the problem that the traffic of other virtual local area networks unrelated to the normal traffic occupies a large amount of ethernet link bandwidth between the first distributed aggregation device 100 and the second distributed aggregation device 300, and the communication efficiency of the normal traffic is reduced is avoided.

Second embodiment

Referring to fig. 5, fig. 5 is a flowchart illustrating a method for dynamically configuring internal control link ports applied to a first distributed aggregation device 100 according to an embodiment of the present invention, where the method for dynamically configuring internal control link ports applied to the first distributed aggregation device 100 includes the following steps:

it should be noted that steps S201 to S203 are the same as steps S101 to S103 in the first embodiment, and therefore, in the embodiment of the present invention, the description of steps S201 to S203 is not repeated.

Step S201, receiving a second list sent by a second distributed aggregation device.

Step S202, determining the virtual local area network to be loaded according to the second list and the first list.

In the embodiment of the present invention, the implementation manner of determining the to-be-loaded virtual local area network according to the second list and the first list may be: and determining the virtual local area networks which exist in the second list and the first list at the same time as the virtual local area networks to be loaded.

Step S203, load the virtual local area network to be loaded to the internal control link port of the first distributed aggregation device.

In the embodiment of the present invention, in order to dynamically adjust the internal control link port 105 of the first distributed aggregation device 100 according to the change of the virtual local area network allowed to pass through by the distributed aggregation interface 104 of the first distributed aggregation device 100, that is, when the virtual local area network allowed to pass through by the distributed aggregation interface 104 of the first distributed aggregation device 100 increases, the corresponding virtual local area network that needs to be increased needs to be dynamically loaded to the internal control link port 105 of the first distributed aggregation device 100, and when the virtual local area network allowed to pass through by the distributed aggregation interface 104 of the first distributed aggregation device 100 decreases and the virtual local area network that needs to be decreased does not pass through by the distributed aggregation interface 104 of the first distributed aggregation device 100 other than the distributed aggregation interface 104 of the first distributed aggregation device 100, the virtual local area network that needs to be decreased is selected from the internal control link port 105 of the first distributed aggregation device 100 Therefore, the embodiment of the present invention further includes steps S204 to S207.

Step S204, when the sharing table has the virtual local area network to be loaded, adding 1 to the reference count of the virtual local area network to be loaded in the sharing table.

In this embodiment of the present invention, a sharing table is stored in the first distributed aggregation device 100 in advance, the sharing table includes an ID of a virtual local area network and a reference count, the reference count of the virtual local area network refers to the number of the distributed aggregation interfaces 104 of the first distributed aggregation device 100 that the virtual local area network is allowed to pass through, for example, the first distributed aggregation device 100 has 3 distributed aggregation interfaces 104: the distributed aggregation interface 1 includes a distributed aggregation interface 1 104, a distributed aggregation interface 2 104, and a distributed aggregation interface 3 104, where the distributed aggregation interface 1 allows a virtual local area network with an ID of 1 to pass through, and the distributed aggregation interface 3 allows a virtual local area network with an ID of 1 to pass through, so that the reference count of the virtual local area network with an ID of 1 is 2. For another example, a virtual local area network with ID 1 and a corresponding reference count 2, a virtual local area network with ID 2 and a corresponding reference count 1 are already stored in the sharing table, if the virtual local area network to be loaded is a virtual local area network with ID 2, and the virtual local area network to be loaded is a virtual local area network with ID 2 and exists in the sharing table, the reference count 2 of the virtual local area network with ID 2 in the sharing table is added with 1, and at this time, the reference count of the virtual local area network with ID 2 in the sharing table is 3.

Step S205, when the sharing table does not have the virtual local area network to be loaded, adding the virtual local area network to be loaded into the exclusive table.

In this embodiment of the present invention, the exclusive table is stored in the first distributed aggregation device 100 in advance, the exclusive table includes an ID of the virtual local area network, and a reference count of the virtual local area network in the exclusive table is 1, that is, there is only one distributed aggregation interface 104 of the first distributed aggregation device 100 that allows the virtual local area network to pass through. When the reference count of the virtual local area network in the shared table is reduced to 1, the virtual local area network is moved from the shared table to the exclusive table, and when the reference count of the virtual local area network in the exclusive table is increased, the virtual local area network is moved from the exclusive table to the shared table. Therefore, when adding the virtual local area network to be loaded into the exclusive table, if the virtual local area network to be loaded does not exist in the exclusive table, adding the virtual local area network to be loaded into the exclusive table, if the virtual local area network to be loaded exists in the exclusive table, moving the virtual local area network to be loaded from the exclusive table into the shared table, and adding 1 to the reference count, that is, the reference count of the virtual local area network to be loaded in the shared table is 2, for example, please refer to fig. 4, the shared table already exists in the virtual local area network 1 and the reference count 2 thereof, the virtual local area network 2 and the reference count 3 thereof, the virtual local area network 4 already exists in the exclusive table, the virtual local area networks to be loaded are the virtual local area network 1, the virtual local area network 3 and the virtual local area network 4, the virtual local area network 1 in the virtual local area network to be loaded exists in the shared table, adding 1 to the reference count of the virtual local area network 1 in the shared table, at this time, the reference count of the virtual local area network 1 in the shared table is 3; adding the virtual local area network 3 into the exclusive table when the virtual local area network 3 in the virtual machine local area network to be loaded does not exist in the shared table and the virtual local area network 3 does not exist in the exclusive table, wherein the virtual local area network 4 and the virtual local area network 3 exist in the exclusive table; the virtual local area network 4 in the virtual machine local area network to be loaded does not exist in the shared table, the virtual local area network 4 exists in the exclusive table, the virtual local area network 4 in the exclusive table is moved to the shared table, the reference count of the virtual local area network 4 is added with 1, and at the moment, the reference count of the virtual local area network 4 in the shared table is 2.

Step S206, when the target vlan deleted from the first list exists in the exclusive table, deleting the corresponding target vlan from the exclusive table and the to-be-loaded vlans loaded to the internal control link port.

In the embodiment of the present invention, for a loaded virtual local area network that allows the distributed aggregation interface 104 of the first distributed aggregation device 100 to pass through, if the virtual local area network does not need to be allowed to pass through any more, the virtual local area network needs to be deleted from the virtual local area network that has been loaded by the distributed aggregation interface 104 of the first distributed aggregation device 100, and the virtual local area network to be deleted is determined as the target virtual local area network. When the target vlan is in the exclusive table, it indicates that the number of references of the target vlan is 1, that is, only one of the distributed aggregation interfaces 104 of the first distributed aggregation device 100 allows its traffic to pass through, the target vlan is deleted from the exclusive table, and the target vlan is deleted from the to-be-loaded vlan loaded to the internal control link port 105 of the first distributed aggregation device 100.

In step S207, when the target vlan deleted from the first list does not exist in the exclusive table, the reference count of the target vlan is decremented by 1 in the shared table.

In the embodiment of the present invention, when the target vlan is in the shared table, it indicates that there are multiple distributed aggregation interfaces 104 of the first distributed aggregation device 100 that the target vlan allows to pass through, at this time, the reference count of the target vlan in the shared table is decreased by 1, but the target vlan cannot be deleted from the to-be-loaded vlan loaded to the internal control link port 105 of the first distributed aggregation device 100, otherwise forwarding of traffic except for the distributed aggregation interface 104 of the first distributed aggregation device 100 corresponding to the target vlan is affected, and when the reference count of the target vlan in the shared table is decreased to 1, the target vlan needs to be moved from the shared table to the exclusive table.

Since the virtual local area network allowed by the internal control link port 105 of the first distributed aggregation apparatus 100 and the virtual local area network allowed by the internal control link port 105 of the second distributed aggregation apparatus 300 can be both manually and statically set, and when the manual and static setting is performed, the virtual local area network allowed by the internal control link port 105 of the first distributed aggregation apparatus 100 and the virtual local area network allowed by the internal control link port 105 of the second distributed aggregation apparatus 300 can be different, in order to ensure that the internal control link port 105 of the first distributed aggregation apparatus 100 and the internal control link port 105 of the second distributed aggregation apparatus 300 only forward the traffic of the virtual local area networks allowed by the internal control link ports 105 of the first distributed aggregation apparatus 100 and the virtual local area networks allowed by the internal control link ports 105 of the second distributed aggregation apparatus 300, the first distributed aggregation apparatus 100 needs to determine, according to the virtual local area network allowed by the internal control link port 105 of the second distributed aggregation apparatus 300, that the virtual local area network allowed by the internal control link port 105 of the first distributed aggregation apparatus 100 is allowed Accordingly, embodiments of the present invention further include steps S208-S211.

Step S208, receiving a fourth list sent by the second distributed aggregation equipment;

in the embodiment of the present invention, the virtual local area network in the fourth list refers to a virtual local area network that is statically set by hand and allowed to be passed through by the internal control link port 105 of the second distributed aggregation apparatus 300, and the second distributed aggregation apparatus 300 sends the fourth list to the first distributed aggregation apparatus 100.

Step S209 determines an effective vlan and a pending vlan according to the fourth list and the third list.

In the embodiment of the present invention, the virtual local area network in the third list refers to a virtual local area network that is statically set manually and allowed to pass through the internal control link port 105 of the first distributed aggregation apparatus 100, the valid virtual local area network refers to a virtual local area network that is statically set manually and allowed to pass through both the internal control link port 105 of the first distributed aggregation apparatus 100 and the internal control link port 105 of the second distributed aggregation apparatus 300, and the to-be-determined virtual local area network refers to a virtual local area network that is statically set manually and allowed to pass through only one of the internal control link port 105 of the first distributed aggregation apparatus 100 and the internal control link port 105 of the second distributed aggregation apparatus 300.

As an embodiment, the method for determining the valid virtual local area network and the pending virtual local area network may be:

firstly, determining virtual local area networks which exist in a fourth list and the third list at the same time as valid virtual local area networks;

and secondly, determining the virtual local area networks which do not exist in the fourth list and the third list simultaneously as the virtual local area networks to be determined.

Step S210, determining the virtual local area network to be added according to the virtual local area network to be determined and the virtual local area network to be loaded.

In the embodiment of the present invention, the virtual local area network to be added refers to a virtual local area network through which the internal control link port 105 of the first distributed aggregation apparatus 100 and the internal control link port 105 of the second distributed aggregation apparatus 300 allow to be statically set manually but dynamically set dynamically.

As an embodiment, the method for determining the virtual local area network to be added may be:

when the virtual local area network to be determined exists in the virtual local area network to be loaded, determining the virtual local area network to be determined existing in the virtual local area network to be loaded as the virtual local area network to be added, for example, the virtual local area networks allowed to pass through by the internal control link port 105 of the first distributed aggregation device 100 are manually and statically set as the virtual local area network 1 and the virtual local area network 2, the virtual local area networks allowed to pass through by the internal control link port 105 of the second distributed aggregation device 300 are manually and statically set as the virtual local area network 2 and the virtual local area network 3, the virtual local area network to be loaded is the virtual local area network 3, the effective virtual local area network is the virtual local area network 2, the virtual machine local area networks to be determined are the virtual local area network 1 and the virtual local area network 3, since the vlan 3 exists in the vlan to be loaded, the vlan 3 is a vlan to be added.

Step S211, determining the valid virtual local area network and the virtual local area network to be added as the virtual local area network that allows the internal control link port of the first distributed aggregation device to pass through.

In the embodiment of the present invention, the active virtual local area network and the virtual local area network to be added are both virtual local area networks that allow the internal control link port 105 of the first distributed aggregation device 100 to pass through.

It should be noted that the second distributed aggregation device 300 in the same distributed aggregation system may also be the distributed aggregation device provided in the second embodiment of the present invention, and there are also steps similar to step S201 to step S211, and the execution time for the first distributed aggregation device 100 to execute step S201 to step S211 and the execution time for the second distributed aggregation device 300 to execute steps similar to step S201 to step S211 may be performed simultaneously, and finally, regardless of manual static configuration or dynamic configuration, the virtual local area networks allowed to pass through by the internal control link port 105 of the first distributed aggregation device 100 and the internal control link port 105 of the second distributed aggregation device 300 are all kept consistent.

In the embodiment of the present invention, the implementation of dynamically maintaining the consistency of the virtual local area networks allowed to pass through by the internal control link ports 105 of the first distributed aggregation device 100 and the internal control link ports 105 of the second distributed aggregation device 300 is performed by using the shared table and the exclusive table, so as to improve the efficiency of program execution, not only dynamically maintaining the consistency of the virtual local area networks allowed to pass through by the internal control link ports 105 of the first distributed aggregation device 100 and the internal control link ports 105 of the second distributed aggregation device 300, but also considering the case that the virtual local area networks allowed to pass through by the internal control link ports 105 of the first distributed aggregation device 100 and the internal control link ports 105 of the second distributed aggregation device 300 may not be consistent when the internal control link ports 105 of the first distributed aggregation device 100 and the internal control link ports 105 of the second distributed aggregation device 300 are manually and statically set, and finally allowing the internal control link ports 105 of the first distributed aggregation device 100 and the internal control link ports 105 of the second distributed aggregation device 300 to pass through regardless of the dynamic or manual and static setting The virtual local area networks are kept consistent, so that the problem of service interruption caused by flow forwarding failure can be avoided no matter the distributed aggregation interface 104 in the distributed aggregation system is abnormal or the link between the distributed aggregation device and the external device 400 is abnormal, and the reliability of the distributed aggregation system is improved.
