Detailed explanation of switch link aggregation [Huawei ENSP]

One . Preface

This note records link aggregation , The content is relatively simple , There are only a few simple commands .
demand ：

6、 Link aggregation is needed between two convergence layer switches to increase bandwidth , Considering the security of the two-layer network and the occupation of network resources, it is necessary to realize the two-layer isolation between different departments .

Manual link aggregation ： Increase bandwidth , Link backup
Make sure it's reliable , Increase bandwidth
Be careful ：1. The interfaces at both ends must be consistent
2. No configuration is allowed under the interface

Two . Experimental process

Let's get two new switches first , Here's the picture ： The link ensures that the ports on both ends are consistent .

Get into SLW9：
Create logical interface group

interface Eth-Trunk 1

Add physical interface g1 mouth ：

trunkport g0/0/1

Add physical interface g2 mouth ：

trunkport g0/0/2

Add physical interface g3 mouth ：

trunkport g0/0/3

Check it out. eth-trunk Interface ：

display eth-trunk 1

Get into SLW10：
Repeat the above steps .
It is mainly necessary to ensure that the interface corresponds . The configuration is as follows

PS：

Configure command shortcut ：

interface Eth-Trunk 1
trunkport g0/0/1
trunkport g0/0/2
trunkport g0/0/3

see eth-trunk Interface ：
