Many thanks to all of you, we have seen how the EVC and QinQ system works. Many many thanks for the test LAB, it is a very valuable resource.

FS team shot more professional-looking videos. I saw the MLAG configuration between the 2 S5850-48 switches and the LACP on the S3910-48 switches, so we can have some kind of "Plug-N-Play" solution. Both of the switch series is equipped with a web GUI for administration and configuration.

Keeping our business uninterrupted is the most important task for us. This switch has 1+1 redundant power supplies. The high availability of the system quite assures us. With its great features like MLAG and VXLAN, we are capable of achieving the scalability of our whole system. I’d like to say FS is the right place to go for networking needs.

This switch is just the right one. Deployed at the core or aggregation layer can both work very well. It’s very flexible for our system configuration. These 40G uplink ports are quite useful. That's also one of the reasons we chose it. Besides, their services greatly kept me informed with the order all the way through. Will buy from them again.

Being new to FS hardware I needed to use their manuals to get these up and going correctly. I also had to put in some calls to tech support, and they did get me up and going. The 2 lost stars are for several items missing from the instruction manuals as well as the poor quality GUI interface. I also have some 3900 series switches who have a much better GUI.

Having used FS optics for years, I've always had great experiences with them. The switch also worked well with FS 10GBASE-T SFP+ Copper RJ-45 30m transceiver module which connected to a nic card via the Cat6a cable. Easy to set up, stable connections, and user-friendly interfaces.

We need some L3 10G switches for our new computer room. Having compared its functions with others, we finally found this S5850-32S2Q is quite strong for our expectations.
Its management functions are quite convenient. We can easily configure and monitor them through the web. That’s really a time saving in our complicated network.
It supports IP routing protocols OSPF and BGPv4. This brings us benefits for load balancing and constructing scalable LANs. With high performance IP routing, it runs efficiently in our network.
We bought them after much thinking. Finally we chose FS just because the performances are good enough.

What I actually need is a managed switch that supports CLI or web interface for a convenient remote management. This switch is just right for my operation and port requirements. It helps a lot to make my network much easy and flexible.

S5850-32S2Q is a good switch with the QSFP+ uplink capability. We have also plugged in transceivers of both optical and 10Gbase-T media types (10GBASE-T SFP+ copper RJ-45 module). It proved that the switch can support 10Gbit/s via optical cable as well as copper cable. The complete materials sent by the AM helpt a lot when we tried to make some configurations. Well worth the money for both its reliability and performance. The first time purchased from FS and there will definitely be countless repurchases.

I really like this switch. Great prices on all of its functionalities, technologies/ protocols:
VLAN Mirroring supports traffic in both directions
Port Mirroring (Many-To-One)
802.1ax link aggregation
LACP
Port and VLAN mirroring
