http://blog.csdn.net/abc_ii/article/details/99918457 Bond mode principles for multiple NICs Linux NIC bindings mode A total of seven kinds (0~6) bond0, Bond1, Bond2, Bond3, Bond4, Bond5, Bond6 There are three types of 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

In Linux, dual-nic binding is achieved by virtualizing two NICs into one Nic. In other words, two NICs have the same IP address, and parallel links are aggregated into one logical link. In fact, this technology already exists in Sun and Cisco, known as Trunking and Etherchannel technology. It is also used in Linux 2.4.x kernel, known as bonding. Under normal circumstances, the network adapter only receives

LINUX Nic (set Nic speed and mode) Ethtool is a command used to query and set Nic parameters. Summary: ethtoolethX // query ethX network port basic settings ethtool amp; ndash; h // Display ethtool command help (help) ethtool amp; ndash; iethX // query ethX network... LINUX Nic (set

The lab server is dual-nic, one connected to the Intranet, and one connected to the Internet. Set proxy on the server, and all machines in the LAN share the internet. However, the server system is Server 2008. I want to use Linux and do not want to change the system. So I installed a virtual machine and Linux on the virtual machine. To enable SSH connection to Linux in the VM over the Internet, the NIC of t

Delete the hidden physical Nic and virtual Nic after network virtualization failure in Windows. In Windows, Nic problems may occur when hardware such as the hardware server motherboard and Nic is replaced, the operating system is restored, or network virtualization fails. For example, an undesired

During hardware power-on initialization, the BIOS checks all PCI devices and assigns a physical address to each device. The address is obtained and written to the configuration space of the device through the bios, And the CPU cannot be accessed directly, the driver can map this configuration space to common memory through ioremap for CPU access. When the operating system is initialized, each PCI device is assigned a pci_dev structure and the previously allocated physical address is written to t

From CentOSRHEL7, the foreseeable naming rules have changed to default. In this rule, the interface name is automatically determined based on the firmware, topology, and location information. Now, even if you add or remove a network device, the interface name remains fixed without reenumeration, and can be replaced seamlessly with the broken hardware. Change the NIC name to eth0. The CentOS operating system is used as an example. 1. Modify the grub S

WhatWhat is an IP alias?In the words of Windows, you configure multiple IPs for a network card.WhenWhat is the occasion to add IP aliases?Web needs, multi-IP access testing, specific software for multiple IP needs ... and so on.HowHere are a few examples of how to use the Ifconfig command to configure an IP alias for a network card.For the configuration of the ip/mask/dns/Gateway/route, see the Routing Configuration summary for the host under the router/linux host/win. Note: Be aware that your

When selecting a device, keep the following restrictions in mind: Do not plug the device after the PCI bridge.

The NIC device name of ifconfig is different from the NIC configuration file, which causes service network restart to fail to start the service, ifconfigrestart When the ifconfig and nic configuration files are named differently Ifconfig displays the NIC name eth1, and the profile name is ifcfg-eth0, which causes

Set dual-physical Nic to virtual Nic in Linux To provide high network availability, We need to bind multiple network cards to a virtual network card to provide external services. This can prevent a network card from being damaged or connection interruption caused by network connection failure. In Linux, we will use eth0 and eth1 to virtualize bond0 as an example: ------ prerequisites for binding: the chipse
