And there are two link aggregation types. There two type link aggregations are :
• Manual Mode • LACP Mode
In manual mode, load balancing is done with all links. In LACP mode, there are active and backup links and backup links are used for redundancy.
Let’s start with Huawei Layer 2 Link Aggregation. For this example, we will use the below topology consist of two switches and three Layer 2 links.
Let’s start to configure Link Aggregation on Huawei Switches in the example topology.
Here, firstly we will enter the configuration mode with “system-view” command. After that we will create Logical Aggregated Link with “Eth-Trunk” command. Then, we will enter each member candidate link and bind this links with Aggregated Logical Link with “eth-trunk” link.
It is time to verify our Huawei Layer 2 Link Aggregation Configuration. We can verify Aggregated Link with “display interface eth-trunk 10” command.
After first configuration example, now, let’s go to the second example and configure Huawei Layer 3 Link Aggregation.
In our topology, there are two routers that are connected eachother with 3 links. In this example, we will aggragete these layer 3 links and build a single logical layer 3 link.
Firstly, let’s start with Router A.Here, we will start with creating Eth-Trunk 20. We will configure this aggregated interface as layer 3 interface with “undo portswitch” command and then, we will add an IP address under this logical Eth-Trunk . Lastly, we enter the member candidate interfaces and bind them with this logical interface, Eth-Trunk.
