Linux can always implement a complex function in the simplest way, especially in terms of NetworkEven if this function is considered to be available only on high-end devices, Linux can easily implement it. The previous articles have already said many times, such as VLAN functions, for example, advanced routing and firewall functions. This article focuses on Linux bonding, which is the functional module of port aggregation. It is undeniable that at the network device level, Linux has developed tw

NIC teaming is one of the many network features introduced in Windows Server-Hyper-V 3.0. The NIC teaming was originally designed for Windows Server 2012 and can now be used to configure a bound adapter for Hyper-V virtual machines. This article mainly describes how to configure NIC teaming on Windows Server 2012 or later. Of course, Windows administrators can u

Linux supports NICs through the kernel. In the early days, many people directly add Nic support during compilation. However, with the increase of NIC types, few have used this thankless method. Currently, most people use the NIC module to drive the NIC. In order to join the network card, you must first know the network

In Linux, dual-Nic binding technology achieves load balancing and failure protection (in Centos5 and Centos6). maintaining high server availability is an important factor in the enterprise IT environment. The most important thing is the high availability of server network connections. NIC binding helps ensure high availability and provide other advantages to improve network performance. We will introduce th

Due to the special position of servers, their reliability, availability and I/O speed become very important, maintainin

Solve the problem that Nic cannot be started after Centos is cloned in vmvm. 0. Previous words: long-standing problems These problems often occur before, but because we cannot find a solution, we can only try to install a new operating system by ourselves, although it is a waste of time, but it cannot be solved. However, it is always difficult to solve the problem. After Various searches and inquiries, I found the following very good solution. After t

Although Microsoft is popular today, many people do not want to abandon Linux. If you want to install Linux, you will find that Linux comes with many Linux Nic drivers, but there are also some uncommon Nic drivers. In this case, you need to install the Linux NIC Driver on your own. NIC Driver Installation and problems
