onboard nic

NIC is "network interface card", referred to as the NIC, English name is network Interface cards, referred to as NIC, also known as network adapter (nia-network Interface Adapter). It is used to realize the physical connection between the networked computer and the network cable, provides a physical channel for the communication between the computers, and carries

bandwidth Bundle 2. Can be detected and automatically failover when a network component fails For example, if you are not configured as "master standby" mode but "double live" mode of network card aggregation, then two 1GbE gigabit NIC can achieve 2Gb total throughput, if it is hooke′s Gigabit NIC can achieve 20Gb total throughput and so on. How many network adapters do Windows Server 2012 support to bun

Ubuntu Configure dual NIC bindings for load Balancing 1, bond working modeThe Linux bonding driver provides a bundle of multiple network interface devices into a single network interface setting for Network Load Balancing and network redundancy.Bonding there are altogether 7 modes of operation: 1), Bond=0, (BALANCE-RR) round-robin policy: (Balanced polling strategy): The transmit packet order is transmitted sequentially until the last transmi

In fact, we previously introduced the Win7 64-bit flagship download appears to be unable to access the Internet for many reasons, although many can be diagnosed by the repair or reset IP, reset DNS and other operations to complete, but sometimes, these commonly used methods are not always can be universal. Recently, there is a netizen consulting said that his Win7 pure version of the computer suddenly can not access the Internet, it seems that the network card has been disabled cause. So how can

Hello everyone, when I went to Lenovo a few days ago, I saw that their engineers installed several NICs on a single machine. The speed was good. I checked it and I went back to the company and found some information on the Internet, dual (multiple) NICs use one IP address technology, which is very useful for various Intranet servers and computers, and, and, I sorted out the information I found on the Internet. Let's take a look, it may be good for everyone! I personally think that using

Use the route command to resolve the following steps:1) determine the network segment of your intranet, if there are more than one listed, for example: 192.168.1.0/24,10.20.0.0/16, etc.2) Determine your intranet network card gateway IP, through NETSTAT-RT can see, for example: Here the first NIC En0 is the wireless network card, The gateway IP is 10.99.1.1, the second NIC EN4 is the wired network card, the

Tangxiang Daily-March 16, 2017:How to add multiple IP addresses to a NIC in Linux network configurationThere are two common ways that Linux systems configure VIPs for network cards: alias IP, and secondary IP=======================================Aliases IP (alias IP)The IP alias is created and maintained by the Ifconfig command of the Linux system, and the alias IP is the second and higher IP that is bound on the

This procedure to solve the CentOS system in some cases, the network card frequently failure caused by the Internet and restart can be normal after the internet phenomenon.This program automatically obtains the gateway address of the ETH0 network card, pings the gateway every 5 minutes, and restarts the NIC command according to the feedback results.After the detection is complete, the test results are displayed on the screen and the logs are saved in

hwaddr=, in which AA:BB:CC:DD:EE: The hardware address of the Ethernet device in the form of FF. On a machine with multiple network card devices, this field is very useful and ensures that the device interface is assigned the correct device name, regardless of the load order in which each NIC module is configured. This field cannot be used with MACADDR. Macaddr=, where the hardware address of the Ethernet device is in the form of AA:BB:CC:DD:EE:F

Overview:There are currently seven types of NIC bindings mode (0~6) bond0, Bond1, Bond2, Bond3, Bond4, Bond5, Bond6There 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 settings.De

One: Principle: Linux operating system under the two-NIC binding has seven different modes. Now the general enterprise will use dual network card access, so that both can add network bandwidth, but also to do the corresponding redundancy, can be said to be a lot of benefits. And the general enterprise will use the Linux operating system with the network card binding mode, of course, now the network card manufacturers will also be some for Windows ope

Double NIC binding order IP address in order to provide high availability of the network, we may need to bind multiple network cards into a virtual network card to provide services, so that even if one of the physical network card failure, it will not cause connection interruption.
