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. Multiple NIC bindings. In order to provide high availability of the network, we may need to bind multiple network cards into a

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
