Overview
The S3900 and S58 series switches give new meaning to flexibility and scalability. Featuring high port densities, switch stacking, MLAG and easy management, the switches are ideal for a variety of applications at every scale. With Gigabit RJ45, SFP, 10G SFP+, security features, and advanced Quality of Service (QoS), the S3900 and S58 series switches act as core, distribution or access layer switches.

Multi-Chassis Link Aggregation Typical Solution
By configuring the M- LAG( Multi-Chassis Link Aggregation Group), the stability of the equipment is enhanced and link redundancy is achieved.
When a "Error-Down" occurs in one link, traffic can be quickly switched to another link.
