The above information indicates that aggregation group 1 is a two-tier dynamic aggregation group with three selected ports.
Summary: 1, China three switch static mode corresponding to the default mode of Huawei, third dynamic mode corresponds to the mode LACP model of Huawei. Cisco is currently only experimenting with Huawei and Cisco, Huawei is mode LACP, Cisco is mode active.
2, the three switches do link aggregation, you need to first create The aggregation interface 1, and then in port gigabitethernet1/0/1 To gigabitethernet1/0/3 add to aggregation group 1 finally Configure two-layer aggregation interface 1 trunk and 20 the message passed.
Before doing Huawei and third switch aggregation connection, there was a problem, and finally consulted a large number of data, only to find that because the configuration sequence problems caused by communication failure, PS: This problem is really not the intention!
Some thoughts on link aggregation of three-way switch in China
