Overview and What Makes Cumulus Linux Stand Out?

The trend of virtualization and automation in the network along with the growing numbers of network users are leading dramatic changes in network infrastructure. The application of locking and proprietary legacy networks has changed. A trend of choosing applications, operating systems, and hardware prevails in modern data centers. Under such circumstances, an operating system called Cumulus Linux is designed to provide an open platform for a faster, easier and affordable network.

altOverview and What Makes Cumulus Linux Stand Out?

What Is Cumulus Linux?

Cumulus Network seized the opportunity from this trend and produced a powerful open network operating system named Cumulus Linux. Cumulus Linux based on Debian Jessie is the first native Linux network operating system for the networking industry, which runs on white-box switches, such as Gigabit Ethernet switch, 10gb switch etc.. It allows consumers to automate, customize and scale with web-scale principles such as the world’s largest data centers. This open approach enables choice with the best hardware, software, application, network architectures, and no vendor lock-in. Cumulus Linux is a solution that allows you to cost-effectively build and efficiently operate your network, just like the world’s largest data center operators, unlocking vertical network stacks.

What Makes Cumulus Linux Stand Out?

Build for automation, scalability, and flexibility, Cumulus Linux is gradually accepted by the public and offers a compelling set of benefits for network engineering and operations team.

Network Administration

Cumulus Linux leverages traditional Linux and networking tools. It can automatically discover network devices and provides advanced troubleshooting with tools such as Cumulus Linux’s prescriptive topology manager for topology consistency against a topology graph.

Network Operation

Cumulus Linux can fully automatic self-configuring, alerts and integration of maps and monitoring data via SNMP with real-time animated topology visualization.

Network Maintenance

Cumulus Linux can express complex logic for alert conditions incorporating dependencies and correlations between metrics. It can generate customizable performance and availability reports on Vlans, network switch ports, subnets, protocols and more.

Network Provisioning

Cumulus Linux allows zero-touch installation and provisioning to simplify operations. It uses embedded Python scripting engine and SQL like query syntax for deep data analysis and capacity forecasting.

Network Efficiency

Cumulus Linux allows consumers to choose compatible hardware and chain control depending on their needs and budgets. By adopting Linux principles for networking, consumers have achieved operational efficiency by 95% and reduced TCO by up to 60%. Therefore, with the help of Cumulus Linux, a simpler, scalable, and faster deployment network can be built.

How Do You Configure a Cumulus Device?

There are three simple ways to configure Cumulus Linux. One is to use a bash prompt which runs the Cumulus Linux. The other is to install Chef, Puppet or CF engine and then use your DevOps pipeline to configure the network devices. Or you can choose to use ONIE (Open Network Install Environment) with local HTTP discovery. But you have to be aware that If your host (laptop or server) is IPv6-enabled, make sure your host is running a web server. If the host is IPv4-enabled, make sure your host is running DHCP in addition to a web server.

What’s the Challenge Ahead?

The networking industry has long believed that the integration of network hardware and software is critical to network speed and reliability. But as technology evolved, it proves that hardware and software work better when they are developed independently. The advantages include faster product development and freedom from vendor lock-in. However, there is no final conclusion about the robustness of network support and the viability of switching suppliers. Cumulus Network says it will support its own software and the third-party hardware on which it runs, and will troubleshoot itself to provide valuable use cases for openness. But on the negative side, the product line offers limited hardware choices. The company requires customers to manage their network infrastructure with tools like Chef, Puppet and the Bash shell. For customers who are not familiar with these tools have to weigh these pros and cons when they are ready to transition to a separate network environment.


Cumulus Linux can run multiple network paths without the needs for multiple switches and offer traffic isolation and network segmentation for multiple devices. It’s the best choice for network flexibility and innovation. Although there are still some challenges on the road ahead, Cumulus Network will continue to find ways to solve the problems and create a better network environment.

Web Smart Switch vs Managed Switch

Speaking of today’s market of network switches, there are three main fiber switches having to be mentioned: unmanaged switch, managed switch and web smart switch. In the previous articles, we compared managed switch with unmanaged switch for home network. In this article, we will continue to make a contrast. So web smart switch vs managed switch, which one should you choose, the decision depends on the size of your network and how much control you need over that network.

alt Web Smart Switch vs Managed Switch

What Is Web Smart Switch?

A web smart switch, also named smart switch or smart managed switch, is a popular option for mid-sized networks that require management. It provides features like QoS (Quality of Service), RSTP (Rapid Spanning Tree Protocol), SNMP (Simple Network Management Protocol), CLI (Command Line Interface), LACP, VLANs, redundancy capability, and so on. Web smart switch is managed via a web browser that provides intuitive guidance for users to manage their networks. It has limited selection of advanced management, poorer scope of configuration flexibility and little to no security features.

What Is Managed Switch?

Similar to web smart switch, a managed switch can be configured and managed correctly to provide a more tailored experience for users. It not only offers tools and means to monitor the network but also gives the network administrator greater control over managing and prioritizing LAN (local area network) traffic. Managed switch allows users in charge of setting everything up, but users have to take all the responsibility for the operation.

Web Smart Switch vs Managed Switch: What’s the Difference?

The differences between web smart switch and managed switch have always been discussed. Here are some obvious differences between them.


Web Smart Switch
  • It offers options like QoS, VLANs, and so on.
  • It’s ideal for VoIP phones, small VLANs, and working groups for places like labs.
  • It allows you to configure ports, basic settings and set up virtual networks.
  • It allows you to assign higher priority to critical traffic.
  • It can divide your network into multiple virtual networks for better traffic security and reliable connectivity.
  • It helps to allocate network bandwidth the way you work.
Managed Switch
  • It provides high-levels of network security, control and management.
  • It can limit access to specific devices, prioritize user traffic and partition a network.
  • It can use layer 3 routing capability to link smaller networks into much larger business-wide networks.
  • It can remotely monitor network performance, detect and repair network problems without having to physically check devices or requiring network services.
  • It can optimize a network’s speed and resource utilization.


A web smart switch is an entry-level managed switch. It’s especially suitable for a business network hosting less than 100 active users. If there is no advanced applications required, web smart switch is the best solution for simple applications such as small and midsize enterprise networks.
An managed switch is ideal for businesses that need to remotely and securely manage and troubleshoot their network. It enables network managers to monitor and control traffic to achieve optimal network performance and reliability. It allows the network to be expanded with flexibility.


Considering the features and functions provided by web smart switch and managed switch, there is no doubt that managed switch is more expensive than web smart switch. Since managed switch allows the network to grow in the future, it worth the price over time.

Web Smart Switch vs Managed Switch: Which Is Best for You?

Web smart switch vs managed switch, the differences do exist. No matter which type to choose, you have to consider your demands first. If you have no limit of expenditure and want to have more control over the network, managed switch is the best choice. If you want to support one small company or colleague with a lower price, web smart switch is good enough. If you don’t know which one suits you best, FS.COM provides various switches to satisfy all your needs.

Managed vs Unmanaged Switch: Which One Can Satisfy Your Real Need?
Managed or Unmanaged Switch for Home Network

Managed or Unmanaged Switch for Home Network

A network switch is a computer networking device, which uses packet switching to connect devices together on a computer network in order to receive, process and forward data to the destination device. There are two common types of switch: managed switch and unmanaged switch, both of which play an important role in home network. So should I use managed or unmanaged switch for home network?

Managed or Unmanaged Switch for Home Network

What Is a Managed Switch?

A managed switch can be configured and managed correctly to provide a more tailored experience for users. It not only offers tools and means to monitor the network but also gives the network administrator greater control over managing and prioritizing LAN (local area network) traffic. Managed switch allows users in charge of setting everything up, but users have to take all the responsibility for the operation.

What Is an Unmanaged Switch?

An unmanaged switch, on the contrary, is a plug-and-play switch that already has all the required program settled, and does not require user intervention, setup or configuration. Here’s one thing to note: the unmanaged switch is manufactured with a standard configuration that cannot be changed, you should think twice before you buy it.

Managed or Unmanaged Switch for Home Network?

Managed switch is able to be configured for more advanced functions while unmanaged switch can’t. Knowing the differences between the two will do a favor in selecting managed or unmanaged switch for home network.

Differences and Similarities Between Managed and Unmanaged Switch

  • They allow multiple devices to connected to the network to communicate with each other.
  • An unmanaged switch is a “plug and play” switch, simply allows Ethernet devices to communicate with one another, such as a desktop PC or router.
  • A managed switch not only provides all the features of an unmanaged switch but also gives you the tools and means to monitor your LAN traffic for a stable and ideal network.
  • A managed switch prioritizes through configuration changes whereas an unmanaged switch is shipped with a fixed configuration and does not allow any changes to this configuration.

Managed Switch for Home Network

A managed switch offers high-levels of network security. It incorporates STP (Spanning Tree Protocol) to provide path redundancy to keep your network safe. So if you need to handle some sensitive information at home, we recommend going with managed switch. It is able to implement VLANs, which allow network administrators to group devices together without running new cables or changing the network infrastructure, to prioritize user traffic for a better performance in a network. A managed switch allows you to configure port mirroring to forward copies of traffic to a single port on the same switch for analysis by a network analyser. The benefit of using managed switch at home is you can diagnose and fix problems without taking the network out of service. In short, a managed switch is ideal for operations that require monitoring and control capabilities. It costs the most, but worth the price over time.

Unmanaged Switch for Home Network

However, an unmanaged switch will work in the most basic form. It can’t be modified or managed. It allows your devices to connect with one another, handles everything automatically. If you’re using unmanaged switch in your home or a small network of fewer than 5-10 computers, it provides ample support. To sum it up, an unmanaged switch is ideal for primary learners with cheaper price.


Now that you know the advantages of managed and unmanaged switches, also the differences between them, you should be able to decide managed or unmanaged switch for home network. For home network, managed switch is for configuring, managing, and monitoring, while unmanaged switch is for simple operating, low in cost. If you are still unsure about the features mentioned above or are confused about the problem confronted, please do not hesitate in getting in touch with FS.COM, we will be more than happy to help with your networking needs.

Top of Rack VS End of Row: Which to Choose for Data Center Network

The topic, top of rack vs end of row, has been under a hot debate when IT technicians talk about data center designs. With the ever-increasing demand for switch-to-server connections in the data center network, the network cabling is required to be more flexible and effective than ever. In that way, a large of installations for greater computing power can be satisfied. Thus, the two commonly deployed designs (top of rack vs end of row) have been put in the spotlight.

Top of Rack (ToR) Design

In a Data Center, there are several racks of servers or storage equipment. Each rack contains multiple computing devices. The top of rack architecture recommends network fiber switches should be placed in every rack to connect with all the computing devices in the rack. In turn, these network switches will be connected to aggregation switches via fiber optic cables.

Top-of-Rack Network Connectivity

Notably, the top-of-rack switch, like a gigabit Ethernet switch, can be put anywhere in the rack, not just limited at the top. However, when in applications, the engineers prefer to put on the top instead of the middle or bottom of the rack for their easier accessibility and cleaner cable management.

End of Row (EoR) Design

In the end of row design, each server in individual racks is required to connect with a common aggregation switch directly, without connecting to individual switches in each rack. Usually, aggregation switches are placed at either end of the “server row” for the purpose of providing network connectivity to the servers within that row. In light of that, the aggregation switch is also called the end of row switch. With such a design, each server cabinet will have a bundle of twisted pair copper cabling containing as many as 48 (or more) individual cables routed to the end of row switch.

End-of-Row Network Connectivity

Just like the top-of-rack switch, the end of row switch may not just be placed at the end of each actual row. Even just a handful of network racks collectively placed in a small row of their own, the end of row switch is still available to provide copper connectivity for more than one row of servers.

Top of Rack vs End of Row

Top of rack vs end of row data center designs are both popular options for data centers and other network arrangements calling for connections with a large number of servers. In fact, it’s hard to decisively say which type is best. Every type shares both advantages and disadvantages.


The top of rack switching can relieve the complexity of cabling and increase the efficiency of on-site deployment. For the reason that all the servers in the same server cabinet are connected to the switch, like 10GBE switches in the same rack, only a few cables go outside the rack reaching to the aggregation switch. In thus doing, fewer cables are installed between the server and network racks, which contributes to a reduction of cable cost. Moreover, this design enables easily upgrade from 1GE/ 10GE network to 10GE/ 40GE network in the future with minimum costs and changes to cabling.
In the EoR design, the number of the device is decreased because not every rack needs to be equipped with switches. Undoubtedly, less rack space is required in the architecture. With fewer devices in the data center, requirements for the cooling system will be reduced which also can save the electric power.


For the ToR, with cables reduced, the number of racks is still increased. The management for switches will be a little bit tricky. In addition, the ToR approach takes up more rack space for the installation of switches.
As for the EoR, with fewer switches used, more cables are needed between racks resulting in the higher possibility of cable mess and higher cost for higher performance cables. Besides, it’s difficult and more expensive to upgrade cabling infrastructure to support higher speed network. Lengthier cables need to be replaced individually while upgrading from 1GE to 10GE, for example.


Top of rack vs end of row data center designs are the common deployments for data center architecture. Considering that each type bears with benefits and limits, you can hardly tell which one is best. Just as the saying, the most suitable, the best.

Managed Gigabit Switch Buying Guide

Nowadays, the managed Gigabit switch has been a hot cake in small and medium enterprise networks. In the context of that, it’s necessary for us to catch the trend and learn something about the managed Gigabit switch so that you can buy it more wisely.

What Is Managed Gigabit Switch?

Before we introduce the managed gigabit Ethernet switch, let’s overview the background information of it firstly. Gigabit Ethernet switch, also called network switch, refers to a box-like device connecting together a number of other devices, such as computers, printers, and servers on a Local Area Network (LAN) and utilize the packet switching to forward data to and from those connections.

While a managed switch is a kind of fiber switch offering a more tailored experience to users. It not only offers tools and the means to monitor the network, but also control over LAN traffic. Managed switches are very much like Virtual Private Servers where you’ll be in charge of setting everything up, managing the device and take responsibility for any configurations that cause downtime.

How to Choose a Managed Gigabit Switch as Required?

According to different features and standards, such as the managed level and the number of ports, the managed Gigabit switch can be grouped into different types. And users can select the required managed switches based on these features.

Managed Level

Based on different managed levels, the managed Gigabit switch can be grouped into the partially managed (smart) switch and fully managed (enterprise) switch. Smart switches have a limited number of options for configuration. However, comparing with the fully managed switch, it can be a cheap managed gigabit switch for home and office use. While fully managed switches are targeted at servers and enterprises, offering a wide array of tools and features to manage the complicated network better.

Number of Ports

Classified by the number of ports, the managed Gigabit switch has been known in a different way. Typically, there are four types are commonly found in the market: 8-port managed gigabit switch, 16-port managed gigabit switch, 24-port managed gigabit switch, and 48-port managed gigabit switch. These ports may be a combination of SFP or SFP+ slots for fiber connectivity, but more commonly they are copper ports with RJ-45 connectors on the front, allowing for transmission distances up to 100 meters. With fiber SFP modules, the distances can be supported up to 40 kilometers.

Buyers Guide

After we have a basic idea of types of managed Gigabit switches. it’s time to remind you some factors should be taken into consideration when you buy a managed Gigabit switch. Firstly, you should clear about the location you want to install whether just for home, office or enterprise. It decides that whether you need to buy a partially managed switch or a fully managed switch.

Then you should review your network environment and think about the number of users your network supports. In a short, the larger your organization is, the more ports you’ll need. For example, if you are a home user, an 8 or 24 port switch is enough, but a 48 port switch, designed for medium or larger network environment, will be a waste of resource.

Through this idea, we can have a basic mind about the background information of the managed Gigabit switch, such as meaning and types. Moreover, we also offer some tips for people who want to buy it. Hope this article can help you choose a right managed Gigabit switch.

What Is SNMP and How SNMP Works

IT System administrators are responsible for collecting work details of the servers and infrastructures, so as to provide a reference for subsequent network adjustment and improvement. But it’s a difficult task in large systems with hundreds or thousands of devices. SNMP protocol is born to solve this problem that lets the technicians monitor the network devices such as data switch, routers and other devices from a single management host. So what is SNMP, and how SNMP works?

What Is SNMP?

SNMP, also written as Simple Network Management Protocol, is an Internet standard protocol implemented on the application layer. The protocol was created in 1898 as a way of monitoring network performance, error rates and so on. The main purpose of SNMP is to define a unified interface and protocol for devices of different categories, versions and manufactures. Thus, assisted by SNMP, system administrators can remotely monitor and manage the numbers of systems and devices on a network, which can greatly simplify their work and improve efficiency of network administration.

How SNMP Works?

Knowing what is SNMP, here we focus on how SNMP works. In SNMP tutorial, to monitor network effectively, SNMP relies on an architecture consisting of the three parts.

SNMP managers: They can be any type of network machine including but not limited to PoE network switch, access servers, etc that has run SNMP to collect and process information of the devices on the network.

SNMP agents: They are the network-management software modules that run on the network node. They are responsible for gathering local system’s information and translating it to an SNMP-specific form.

Network management station: It’s the base that is shared between agents and managers. And it offers the memory and processing resources to the network.

SNMP works by sending message which is called protocol data units (PDUs) between SNMP managers and agents. Using SNMP queries, the manager can identify and locate the devices by receiving the responses sent by the agent. Then the monitoring tool will record and analyze the information of device performance. Thus, the administrators can manage the devices through SNMP control commands. The following picture shows how SNMP works.

Using SNMP to Monitor Network Device

To help IP administrators solve monitoring issue, FS.COM has released a series of switches including 10gbe switch, 40gbe and even 100gbe switch that are equipped with SNMP function.

The S5800-48F4S is a low latency L2/L3 switch with 48 1GbE SFP ports and 4 10GbE SFP+ ports. It supports MLAG, MPLS, SNMP etc, which is perfect for traditional and fully virtualized data center. As for the SNMP configuration, first you should enter the switch administrative interface. Then find the SNMP tab, and select Enable. And follow the commands to create your SNMP account. Thus, you already are enabled to use SNMP to monitor your network.
