Embodiment 1

[0052] This embodiment illustrates the present invention through specific actions of two devices in the MST domain. Wherein, the first device is a device that actively initiates modification of domain configuration information, and the second device is any device that modifies domain configuration information in response to a domain configuration message of the first device.

[0053] Please refer to figure 2 The method for modifying the domain configuration information of the MST domain described in this embodiment, when applied to the first device, includes:

[0054] Step 21, when the user needs to modify the domain configuration, for example, the domain configuration information needs to be modified from the current first domain configuration information to the second domain configuration information, and the second domain configuration information will be input to the first device. After receiving the configuration information of the second domain entered by the user, the...

Embodiment 2

[0091] This embodiment provides another method for modifying the domain configuration information of the MST domain, such as Figure 7 shown, including the following steps:

[0092] Step 71, before modifying the MST domain configuration, mark the intra-domain ports of all devices in the MST domain as mandatory intra-domain ports, wherein each device judges the MSTP packets received on its own mandatory intra-domain ports as intra-domain packets .

[0093] Step 72, modifying the domain configuration information of each device in the MST domain, and after the domain configuration information of all devices in the MST domain is modified, clearing the mandatory intra-domain port flags of each device.

[0094] In this embodiment, in the process of modifying the domain configuration information, the MSTP message received on the port in the domain will not cause network topology oscillation, thereby improving the service quality of the network.

[0095] To sum up, this embodiment c...

Abstract

The invention provides a method and devices for modifying domain configuration information of a multi-spanning tree domain. The method configures a packet in the MST domain, meanwhile, all the devicesin the MST domain all re-send the newly modified domain configuration information after delaying a period of time, and all the devices all judge the received MSTP packet carrying the new and the olddomain configuration information as the packet in the MST domain after a period of time of modifying the domain configuration information, thereby reducing the occurrence of network topology oscillation and improving the service quality of a network.

Description

technical field [0001] The present invention relates to the technical field of Multiple Spanning Tree Protocol (MSTP, Multiple Spanning Tree Protocol), in particular to a method and equipment for modifying domain configuration of Multiple Spanning Tree (MST, Multiple Spanning Tree) domains. Background technique [0002] MSTP is a new spanning tree protocol defined in IEEE 802.1s. MSTP introduces the concept of "domain" and divides a switching network into multiple MST domains (Multiple Spanning Tree Regions). The MST domain is composed of multiple devices in the switching network and the network segments between them. There are physical links between these devices. [0003] MSTP can implement VLAN-based load balancing in a domain, which requires that the domain configuration information of each device in the domain must be the same. Domain configuration information includes domain names, MSTP revision levels, VLANs, and mapping relationships between spanning tree instances...
