Embodiment 1
[0095] Please refer to Figure 4 , Embodiment 1 of the present invention provides an isolation configuration method based on a cross-chassis link aggregation group MLAG, including:
[0096] S101: Configure the unidirectional isolation attribute of the member ports of the dual-homing MLAG group, the dual-homing MLAG group is established by the first switch and the second switch in a dual-homing access mode for networking;
[0097] S102: Detect whether the dual-homing of the dual-homing MLAG group has changed;
[0098] S103: If a change in the dual-homing of the dual-homing MLAG group is detected, change the unidirectional isolation attribute of the member ports of the dual-homing MLAG group.
[0099] In the specific implementation process, the specific implementation process of step S101 to step S103 is as follows:
[0100] First, the first switch and the second switch are networked in a dual-homing access mode to establish a dual-homing MLAG group. In other words, after the devices at ...
Embodiment 2
[0161] Based on the same inventive concept as the first embodiment of the present invention, please refer to Figure 14 The embodiment of the present invention also provides an isolation configuration device based on the cross-chassis link aggregation group MLAG, including:
[0162] The configuration unit 10 is configured to configure the unidirectional isolation attribute of the member ports of the dual-homing MLAG group, the dual-homing MLAG group is established by the first switch and the second switch in a dual-homing access mode for networking;
[0163] The detecting unit 20 is configured to detect whether the dual-homing of the dual-homing MLAG group has changed;
[0164] The modification unit 30, if the detection unit detects that the dual-homing of the dual-homing MLAG group has changed, changes the unidirectional isolation attributes of the member ports of the dual-homing MLAG group. In the embodiment of the present invention, the configuration unit 10 is used to:

Abstract
The invention discloses an isolation configuration method and a device based on a cross-chassis link aggregation group MLAG, wherein, the method comprises the following steps: configuring the unidirectional isolation attribute of a member port of a dual-homing MLAG group, wherein the dual-homing MLAG group is set up by a first exchange and a second exchange in a dual-homing access mode; detectingwhether the dual attribution of the dual-homing MLAG group is changed; if a dual homing change of the dual homing MLAG group is detected, changing a unidirectional isolation attribute of a member portof the dual homing MLAG group. The method and the device are used to solve the time consuming technical problem of the existing unidirectional isolation mechanism.
Description
Technical field [0001] The present invention relates to the technical field of data communication, in particular to an isolation configuration method and device based on a cross-chassis link aggregation group MLAG. Background technique [0002] In order to improve the availability of the network, the industry proposed MLAG (Multi-chassis Link Aggregate Group, cross-chassis link aggregation group), which is a mechanism to achieve cross-device link aggregation, which combines physical links on different devices into a logical chain Link aggregation group, thereby improving the link reliability to the equipment level, forming a dual-active system (or dual-homing system), such as figure 1 Shown. [0003] Among them, the peer-link peer-to-peer link is a direct link between dual-homing devices (including the MLAG master device and the MLAG backup device), and link aggregation must be done to exchange negotiation messages and transmit part of the traffic. In order to increase the reliabi...
