It is not possible to set the same IP address directly for two NICs. Through bonding, a virtual one network card to provide external connection, the physical network card is modified to the same MAC address2 NIC Binding classificationThere are seven mod

? The two-Nic binding implementation is the use of two network card virtual become a network card, the aggregation of the device appears to be a separate Ethernet interface device, the popular point is that two network cards have the same IP address and parallel link aggregation into a logical link work. Depending on the features that the switch can support, the most common is a dual-NIC binding that is set

Linux virtual machines on Hyper-V is the NIC driver, and when we created a new Linux virtual machine, we found that the NIC was not available when we turned the Linux system on. Because Linux systems, whether Rhel or Ubuntu or poop, do not support Hyper-V NIC drivers. This requires us to remove the network Adapter NIC

A test machine is installed in the IDC. The system is Ubuntu9.04X64 and the master machine is IBMX336. The user needs a dual-line connection. Therefore, one Nic is used to configure the telecom address, and the other Nic is configured with the UNICOM address. After the system is installed, only one Unicom address and one Telecom address can be pinged, if the China Unicom address does not match the gateway,
