How to Configure MLAG (Multi-Chassis Link Aggregation)?

FS Official 2018-10-10

MLAG (Multi-Chassis Link Aggregation Group) allows two switches to be interconnected through link aggregation, and act as one logical switch. Using this configuration can avoid data losses when there's an emergency that a link or a switch fails to work. This video gives detailed steps of how to configure MLAG with specific commands on FS S5800 series switches and how to confirm it's working successfully.

Let's first learn how MLAG works when the unexpected incident happens. The two switches in an MLAG group negotiate with each other through the peer link and decide the master and slave, and synchronize info through peer link in a real time. By doing this, if one link is down (not the peer-link), the whole network still can work normally; if one network switch breaks down, all the data will be transferred through another switch.

By watching this video you will learn how to configure MLAG, how to do MLAG verification and LACP verification, and how to use port-mirror to check the function of MLAG. To help understand the steps of configuring MLAG and the function of MLAG, we build a typical MLAG application scenario with FS S5800 switches and S3800 switches (S3800 switches have been updated into S3900 switches), and configure MLAG on them. The S5800-8TF12S is a 10G data centre high-performance Ethernet switch. It has 12 SFP+ ports and 8 1G SFP/RJ45 ports, which is perfect for hyper-converged infrastructure.
