For the server, network equipment Stability is also more important, especially the network card. In a production-type system, the reliability of the NIC is even more important.Multiple NICs are bound to an IP address, and when a network card is physically damaged, another NIC is automatically enabled and provides normal serviceThat is: By default, only one network card works, the other network cards do back

Linux supports NICs through the kernel. In the early days, many people directly add Nic support during compilation. However, with the increase of NIC types, few have used this thankless method. Currently, most people use the NIC module to drive the NIC. In order to join the network card, you must first know the network

We all know that any site on the network, including routers, switches, servers, and general sites, must communicate with the network through the NIC. As the number of sites on the network increases, the use of network cards naturally increases. Nic faults also increase significantly. Many users do not pay enough attention to the network card. For example, the cheapest network card is tens of RMB, while the

In this way, the following problems exist:Question 1: Mac conflict description: The cloned system Nic eth0 may be consistent with the system before cloning, resulting in MAC conflict;Solution: 1. Modify Mac in CAT/etc/udev/rules. d/70-persistent-net.rules 2, to CD/etc/sysconfig/network-scripts/to modify the original network card eth0 configuration file ifcfg-eth0 Mac and/etc/udev/rules. d/70-persist

increasingly prevalent. This article will introduce the multi-Nic bonding technology in Linux to describe this fault tolerance concept. Server load balancer is another feature of network card bonding. it can work with multiple network cards at the same time to improve the throughput of system network processing. 1.

Linux can always implement a complex function in the simplest way, especially in terms of NetworkEven if this function is considered to be available only on high-end devices, Linux can easily implement it. The previous articles have already said many times, such as VLAN functions, for example, advanced routing and firewall functions. This article focuses on Linux bonding, which is the functional module of port aggregation. It is undeniable that at the network device level, Linux has developed tw

Writing time: February 22, 2015 Sunday 1 overviewWith the promotion and acceptance of the public cloud, we find the value and advantage of the public cloud, but in many scenarios we still need to deploy many network virtual appliances, and for most of these network virtual appliances deployed in Azure, multi-NICs are a basic requirement and need to provide greater capacity to manage network traffic. The multi-NIC feature allows you to create and manag

Configure the NIC Bonding for the RAC Private Network In the installation and deployment process of RAC, it is not just a simple installation. The possible single point of failure (spof) should be considered during the installation process. The most important part is the private network. A private network is a channel for communication between RAC nodes, including network heartbeat information between nodes and data blocks transmitted through Cache fu

Centos6.5 multi-nic configuration redundancy (bond) Why do we suddenly remember to configure this? When I went to the data center for implementation last time, I found that most servers have at least two NICs inserted with network cables to connect to switches, but they may have only one ip address, the redundant Nic must be redundant or load balancing. In the following experiment, we will mainly use vmwa

In the virtual machine, when the RAC configures the public Nic sequence method, when the dual Nic is configured, one is public and the other is private, there is always an error, that is, through ipconfig/all, command to view the order of the network card, always the first private type of IP network segment. Solution: the root cause of this problem is that when the NIC
