dual 10g nic

(This article was previously reproduced on the Internet and has been modified. I will repeat it after my operations) In the past, I installed a dual Nic on my computer (not a server) to facilitate the test. The dual Nic accesses two different networks but can access the Internet. Recently, in order to build and test a

In the current production environment of the server, dual-NIC binding has become a standard, in theory this technology is very good, the following we began the operation of this experiment.The first preparation requires two virtual machines, Server01 is the target server, requires two network cards, and empties the existing configuration of the two NICs, Server02 as a test machine.650) this.width=650; "Styl

Dual NIC BindingAdvantages of dual NIC bindings: First: Network fault tolerance can be achieved (main master mode, main standby mode) Second: Bandwidth binding (Systems prior to Windows Server 2012 must take advantage of the software provided by the server manufacturer; the operating system after Windows Server 2012 ca

It is impossible for a dual-nic computer to have two gateways, because the default gateway can only be one. Install two NICs for the UbuntuLinux server and set different ip addresses and gateways (intranet and Internet) respectively. The Internet can be accessed through the Internet Nic, and the Intranet can be accessed through the Intranet

1. Network Structure Machine 1: the operating system is RedHat liuux9.0, and access the Internet through the Intranet gateway 192.168.0.252. Two NICs, eth0 and eth1, are installed. The network settings are as follows:Eth0: IP = 192.168.0.180/24, netgate = 192.168.0.252Eth1: IP = 192.168.0.181/24Machine 1 also has the squid agent software installed. Machine 1 can access the Internet normally. Machine 2: Windows, IP = 192.168.0.182/24, a network card, connect to the network card eth1 of machine 1

Recently there is a demand, the switch has two, do a stack, the server dual network card, each connected to a switch. This requires the server's network card into the main standby mode to increase security, so that when one of the switches is not available, the network card can automatically switch.The overall configuration is not difficult, there are corresponding tutorials on the Internet, there may be some version of Ubuntu is different, so the con

Windows XP's "Bridge" feature comes in handy, but a prerequisite is that a Windows XP system client with a dual NIC installed on the l

To bind a CentOS dual-Nic, you can use two NICs to virtualize an ENI (which must be supported by a switch). The aggregated device looks like a separate Ethernet interface device, in general, two NICs have the same IP address, and parallel links are aggregated into a logical link. This document describes in detail how to bind a dual-network card to centos6.4. befo

As we need to conduct ESXI-related experiments, we will use VM Virtual ESXI on our own machine for the experiment. Because this experiment requires two NICs, we added two NICs when creating an ESXI virtual machine. As follows: Ho

Root cause:Reverse route checking is enabled by default on LinuxIf 2 network cards are inside a LAN, then the server may find the gateway from eth0 or eth1, if a packet from eth0 into the gateway on eth1, then from the eth1 is out of the way, it will not pass. The reverse route check asks where it came from to go back.Turn off reverse route checking (replace the network card name of the second third row, depending on your situation):echo 0 >/proc/sys/net/ipv4/conf/all/rp_filterecho 0 >/proc/sys/
