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

The server on the customer side is Windows OS, and the business operation on our side requires linux OS. Therefore, we installed VMWare on Windows OS. However, when conf

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

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
