CentOS7.1 Nic settings Today, I installed CentOS7.1, and found that it was very different from that before 6. The command changed a lot and the network configuration was not as good as that. Next I will introduce the NIC configuration in 7, including the problems I encountered. After the VM is installed Run ifconfig You will find that the NIC information has

Currently, many organizations have built internal lan. Most enterprise networks use twisted pair wires to connect to NICs for communication. Among them, twisted pair wires generally use 5 types of lines with a transmission rate of 100 MB. There are some differences between NICs. Many NICs adopt 10 Mbps/mbmps adaptive NICs, that is, the transmission rate automatically matches between 10 MB and MB. For such NICs, theoretically, a file of a dozen MB can be transmitted within several seconds, but it

Select "advanced"> "Advanced Settings", and select the corresponding network adapter under "connection in the order accessed by network services, click the up or down button on the right to set the NIC priority.

Study Notes of AM335x (TQ335x) -- Nand NIC Driver porting, am335xtq335x After the sound card driver was transplanted, I wanted to continue and transplant the NIC Driver. However, I did not expect that the kernel maintained by TI is too robust. porting the NIC Driver is as simple as porting the key driver. The same is true for the Nand driver, I will introduce Na

U-boot-2014.10 port 18th days ---- add DM9000 Nic support (2), holiday scheduleModify code Accidentally deleted this blog, and the recycle bin did not save the draft. Now I can write it again! DM9000 itself also has a base address. This base address is bound by the TXD [] (strap pins) pin. The formula is met: IO base = (pin value of TXD []) * 10 H + 300 H TXD [] pins are in 8 state, so I/O base addresses have eight base addresses: 300 H, 310 H, 320 H,

After using VMware to clone a virtual machine, the Wakahara host NIC name is Eth0, then the cloned host uses Ifconfig to see only a network card named Eth1.And in/etc/sysconfig/network-scripts/this directory only has ifcfg-eth0 a network card configuration fileThe Ifcfg-eth0 device property is also eth0Then we cannot modify the network address and status of the eth1 displayed in Ifconfig, we need to make the Eth0 configuration file effective in order

Assuming that Eth0,eth1,eth2,eth3 is bound to bond0, the steps are as follows:(1) #vi/etc/modprobe.conf, add the following 2 lines: Alias bond0 bonding options Bonding miimon=100 MoD E=4When mode=0, the corresponding port of the switch does not need trunk, but the Ping Gateway (192.*.*.*) from the node has a large delay. The solution to this problem is to change mode to 4, while configuring the switch corresponding port to turn on link aggregation and bundle as trunk.In the modprobe.conf file,Th
