Abstract

The invention discloses an attribute registration method for a switched network and switching equipment. The method comprises the steps that: the switching equipment receives registration messages from other switching equipment in the same switched network, wherein the registration messages comprise the attribute information of instantce-vlan mapping relation between a multiple spanning tree instance and a virtual local area network; and the switching equipment updates the instantce-vlan mapping relation of the switching equipment according to the attribute information of the instantce-vlan mapping relation in the registration messages. In the invention, the switching equipment in the same switched network can learn the instantce-vlan mapping relation of the other switching equipment and also can transmit the local instantce-vlan mapping relation to the other switching equipment, so that the automatic configuration of instantce-vlan attributes can be realized; and by registering the instantce-vlan attributes into a sending port and a receiving end, the two-way transmission of the instantce-vlan attributes is realized, so that a looped network is supported.

Description

technical field

[0001] The invention relates to the field of computer network communication, in particular to an attribute registration method and switching equipment for switching networks. Background technique

[0002] With the development of Ethernet technology, Ethernet switches are more and more widely used. However, due to the large number of Ethernet switch devices, the configuration of attributes becomes more complicated, especially for low-end devices, and the configuration commands are more cumbersome. The GARP (GenericAttribute Registration Protocol, Generic Attribute Registration Protocol) protocol and the application protocols GVRP (GARP Vlan Registration Protocol, GARPVlan Registration Protocol) and GMRP (GARP Multicast Registration Protocol, GARP Multicast Registration Protocol) defined by GARP have emerged. These two protocols, GVRP and GMRP, are used to dynamically maintain the vlan (Virtual Local Area Network, virtual local area network) registration inform...

Examples

Embodiment 1

[0038] The attribute registration method provided by the present invention and the switching equipment with this registration function are based on a specific application of the GARP standard, and realize the automatic registration of the instance-vlan mapping relationship of the switching equipment in the same exchange. In this embodiment, processing The function of module 20 can be finished by command line submodule 202 and message processing submodule 204, as image 3 As shown, the processing module 20 includes: a command line sub-module 202 and a message processing sub-module 204 , which are coupled to each other and realize automatic registration of the instance-vlan attribute under the control of the timer module 40 .

[0039] The command line sub-module 202 is used to enable or disable the instance-vlan registration function of the switching device, including a global switch and a port / trunk switch. The command line sub-module 202 needs to perform a series of judgments,...

Embodiment 2

[0045] This embodiment describes the processing flow of the received registration message, such as Figure 4 shown, including the following steps:

[0046] In step S402, the switching device receives registration messages from other switching devices in the same switching network.

[0047] Step S404, judging whether the message type is a LeaveAll message.

[0048] Step S406, if yes, start the LeaveAll timer.

[0049] Step S408, judging whether a Join message is received before the LeaveAll timer expires.

[0050] Step S410, if no Join message is received before the LeaveAll timer expires, cancel all learned instance-vlan mapping relationship attributes, otherwise, process the Join message.

[0051] Step S412, if the type of the received message is not LeaveAll, it is judged whether the instance-vlan attribute information carried in the message exists in the switching device.

[0052] In step S414, if the attribute information does not exist in the switching device, it is j...
