xmit_hash_policy=layer3+4"Note: The Miimon is used for link monitoring. For example: miimon=100, then the system every 100MS monitoring link connection status, if one line is not connected to another line; The value of mode indicates the mode of operation.The mode=0 indicates that load balancing (round-robin) is balanced, and both NICs work. Load-balanced operation mode that provides twice times the bandwidth. In this case, the failure of a network card will only be the server egress bandwidth

VMware cloning Centos6.4 virtual machine NIC does not start problemIn the course of learning, it is found that the following problems cannot be solved. Quickly create a Linux virtual machine version of centos6.4 with the full cloning feature of Vmware8. post-creation symptoms: Use ifconfig after startup, no IP address found, only loopback address is 127.0.0.1, mac address and host name are the same as the source host (IP configured by the source host

Overview: There are currently seven types of NIC bindings mode (0~6) bond0, Bond1, Bond2, Bond3, Bond4, Bond5, Bond6 There 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 setti

When we use FreeBSD as a gateway or firewall, we require two network cards to be installed in the system, spanning two networks, one card for the external network, and the other for the internal network. Well, as you know, it's time to get the system to support these new devices, and for the network adapters, FreeBSD is supported by a custom kernel. Of course, first let the kernel understand the hardware resources used by the device, for the NIC using

In order to improve the high availability of the system, we can bind two or more network cards into a virtual network card, using the same IP address, to ensure that a link is broken, another link can be activated at any time, improve the stability of the system. Dual NIC enabled in virtual machine Finish Dual network card when working as a virtual network card (BOND0), the virtual NIC also needs to

After the virtual machine clone is started using Ifconfig, no IP address is found, only the loopback address is 127.0.0.1,The MAC address and host name are the same as the source host (the source host is manually configured IP).Any execution of the following commands is useless anyway:/etc/init.d/network restartIfup eth0Workaround:1. Edit the eth0 configuration file: Vi/etc/sysconfig/network-scripts/ifcfg-eth0, delete the hwaddr address the line and UUID lines are as follows:hwaddr=00:0c:29:2c:6
