Three Approaches to Log in to Your Network Switch

Three Approaches to Log in to Your Network Switch Generally, a network switch can be used directly after purchasing. Well, if users want to configure VLAN or shut a port or something, they need to make some changes on it, which requires them to first login the switch. The following three common login methods are illustrated in details by using the FS 3900-24F4S switch as an example. They are the widely used local console port login, the remote login by ...

RoCE: RDMA over Converged Ethernet for High-Efficiency Network Performance

In the era of data, the requirements for a faster, more efficient, and scalable network has never been reduced. Since the traditional TCP/IP Ethernet connections are CPU intensitive and require extra processing and copying of the data, they can’t meet the current network needs any more. In that context, the RDMA over Converged Ethernet (RoCE) arrives. Background Knowledge: What Is RDMA? RDMA (remote direct memory access) is a technology that enables direct memory access from the memory of on...

How to Configure MLAG on FS N-Series Switch With Cumulus Linux?

Data center and cloud computing networks require both the highest level of network bandwidth and reliability. MLAG (Multi-Chassis Link Aggregation) makes it possible by taking the benefits of link aggregation, and spreading them across a pair of data center switches to deliver system level redundancy as well as network-level resiliency. It significantly improves network efficiency and simplifies system management, which can be used at various places in the network to eliminate bottlenecks and pr...

Using Cumulus Linux VRR to Ensure Reliable Network

With the rapid development of the Internet, increasingly high requirements are imposed on the reliability of networks. It’s vital for users to focus on keeping the accessibility to external networks when the network fails. There’re many measures that IT staff can do to reach the uptime goals, such as using physical redundancy solution, providing battery backups in case of an outage. They can also configure logical redundancy by Cumulus Linux VRR or standard VRRP to ensure the reliability of the ...

Ring Protection Protocol: ERPS vs. EAPS

Used for ring topology, the ring protection protocol adopts the pervasion mechanism to transmit the change of network topology, which is critical to reduce interference between nodes and extend lifetime of the network. Ethernet ring protection switching (ERPS) and Ethernet automatic protection switching (EAPS) are two types of ring protection protocol. Here makes a detailed illustration of ERPS vs. EAPS. What Is ERPS and How Does It Work? ERPS (Ethernet ring protection switching), is a proto...

NCLU Smooths Networking Transition to Cumulus Linux

The communication industry is embracing Linux-based switch hardware and software to build affordable, agile and high-capacity networks. However, to maximize operational efficiency, IT engineers need not only advanced network functions, but also more concise command line interfaces and configuration approaches - because even the command lines of various Linux-based switches are similar, not all the engineers are necessary with a Linux background. To simplify network configuration and make Cumulu...

Does an Open Switch With Cumulus Linux Equal a Proprietary Switch?

As you may know that open network is a hot topic these days. It is enabled by several parts such as open source software, open compute hardware, etc. Under this trend, another related topic, open switch, has caught much attention as well. Then, what is open switch? How does it differ from the traditional proprietary switch? In this post, we will focus on the comparison on a proprietary switch (Cisco, Juniper and HPE switches, etc.) and an open switch preloaded with the open source software Cumul...

100G Switch: Bare Metal One or Preloaded Cumulus Linux or ICOS?

100G switches, sounds futuristic? Not really, 100G is here and being deployed. Actually, since 2015, companies like Google, Microsoft or Amazon have started their migration toward 100G. And many of their 100G deployments adopted 100G open source switches for web-scale or hyper-converged data center architectures. However, there are many choices on the market, such as the brite box switch that preloaded with open source software like Cumulus Linux or ICOS and etc, and the bare metal switch withou...
