Embodiment Construction

[0043] Such as figure 2 As shown, the VLAN information transmission method includes: when sending VLAN information, the VLAN information includes a valid VID determined according to one or more virtual local area network identifier (VID) selection rules, or when sending VLAN information, the VLAN information It includes one or more types of VID selection rules and parameters used by each VID selection rule to indicate the range of VID selection.

[0044] The VLAN information is information configured for one or a combination of device nodes, aggregate interfaces, sub-interfaces, and cross-rack aggregation identification (D-LAG-ID); the VLAN information includes device nodes , Aggregation interface, sub-interface, cross-rack aggregation identification (D-LAG-ID) one or more information.

[0045] The VID selection rule is an inclusion rule, a parity rule, or an exclusion rule;

[0046] The inclusion rule is used to indicate that the VID indicated by this rule is valid, and the parame...

Abstract

A method and an apparatus for transmitting virtual local area network information. The method comprises: sending virtual local area network information, the virtual local area network information comprising a valid virtual local area network identifier (VID) determined according to one or more VID selection rules, or, the virtual local area network information comprising types of one or more VID selection rules and a parameter of a VID selection range indicated by each VID selection rule. By comprehensively applying a rule such as an inclusion rule, an odd-even rule, or an exclusion rule to simplify configuration of the VLAN information, and in combination with a node, an aggregation interface, a sub-interface, and a distributed link aggregation group identifier (D-LAG-ID), service traffic may be flexibly assigned, consecutive VLAN information is compressed during encoding, and special encoding is performed for different information, thereby reducing information traffic during protocol interaction.

Description

Technical field [0001] The invention relates to data communication technology, in particular to a virtual local area network (VLAN) information transmission method and device. Background technique [0002] Such as figure 1 Shown is a distributed Link Aggregation Group (LAG) system based on the Link Aggregation Control Protocol (LACP) technology specified in the 802.1AX standard. In this system There are some new features. One of the important features is to protect the network part of the interconnection interface, not to block certain ports, to give full play to the bandwidth of the network, and to meet the requirements of protection, load balancing, and redundancy. [0003] From figure 1 I see a service gateway interface, which is used to determine how the service flow is forwarded. The basis of the judgment is the need to obtain relevant information, but at present it is only known to forward according to the VLAN, and the configuration method of the relevant VLAN information i...
