Overview: There are currently seven types of NIC bindings mode (0~6) bond0, Bond1, Bond2, Bond3, Bond4, Bond5, Bond6 There are three kinds of commonly used: Mode=0: Balanced load mode with automatic redundancy, but requires "Switch" support and settings. Mode=1: Automatic redundancy mode, where one line is disconnected, other lines will be automatically redundant. MODE=6: Balanced load mode with automatic redundancy without "Switch" support and setti

When we use FreeBSD as a gateway or firewall, we require two network cards to be installed in the system, spanning two networks, one card for the external network, and the other for the internal network. Well, as you know, it's time to get the system to support these new devices, and for the network adapters, FreeBSD is supported by a custom kernel. Of course, first let the kernel understand the hardware resources used by the device, for the NIC using

In order to improve the high availability of the system, we can bind two or more network cards into a virtual network card, using the same IP address, to ensure that a link is broken, another link can be activated at any time, improve the stability of the system. Dual NIC enabled in virtual machine Finish Dual network card when working as a virtual network card (BOND0), the virtual NIC also needs to

If the NIC that is being used to receive data fails, it is taken over by other network cards, and the network card and the NIC driver are required to get speed information through the Ethtool command.Balance-alb or 6: Adapter input/Output load Balancing mode, on the basis of "mode 5", while

In the XP system, dual-nic Internet access is absolutely feasible, and dual-host interconnection in XP is not required. With the development of the times, computers are becoming increasingly popular in today's homes, and many families already have two or more computers. For these users, how can they connect two computers together to form a minimal LAN for sharing files, playing games online, sharing printers, and other peripherals, even Internet acces

Linux Kernel upgrade-update NIC DriverThe current kernel (2.6.32-220. el6.x86 _ 64) upgrade to the target kernel (2.6.33-110. el6.x86 _ 64), but the compiled target kernel (2.6.33-110. the corresponding driver of el6.x86 _ 64) does not necessarily support the corresponding device of the current system.

In the "Device Manager" on the computer, many people have names such as "#2" and "#3" behind the network card. If your computer has only one network card, this indicates the driver of the NIC.ProgramYou have been installed on your computer at least twice. Why is this happening? This is because you have changed the expansion slot of the NIC. For intentional or unintentional purposes, you may change the NIC

Many home users access the residential broadband through ADSL dial-up Internet access. When using this method to access the Internet, they often encounter a failure in dial-up Internet access! This is not the case. When we perform hardware plugging and unplugging operations on the computer at will, some Nic devices are "allergic" to this kind of plugging operation, resulting in the failure of dial-up Internet access. Now, this article will contribute

Since it is the MAC header information created by the driver, you can enter the address information at will, and th

For the server, network equipment Stability is also more important, especially the network card. In a production-type system, the reliability of the NIC is even more important.Multiple NICs are bound to an IP address, and when a network card is physically damaged, another NIC is automatically enabled and provides normal serviceThat is: By default, only one network card works, the other network cards do back
