How to adjust GI configuration after renaming a private Nic in Oracle 11gR2 RAC Environment Environment Description: AIX + 11gR2 RAC dual-nodeCause: the two NICs used for private network communication use a gigabit Nic. Now, they need to be replaced with a 10-Gigabit Nic. Because a 10-Gigabit Nic is a card and a port,

How to send packets from the network adapter: ArticleSource: http://blog.21ic.org/user1/1066/archives/2007/40803.html An IP packet can be considered as a packet. Linux NIC DriverProgramAdd a 14-byte MAC header to the IP packet to form the Mac packet. The Mac package contains the MAC address information of the sender and receiver. Since it is the MAC header information created by the driver, you can enter the address information at will, and th

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

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

What happened in these months is still quite a lot, for a new company, OpenStack Harvest or some, of course, this is to learn by themselves, but completely into an outsourced project feeling, I am a bit uncomfortable. If you do anything, you need documentation, then my creative mind is not erased? I believe in my ability to learn, so I must have consciousness, accumulated over the accumulation of thin hair. Alas, but I feel that I still have a bit of failure, life from time to time will be confu

ubuntubonding (NIC binding)binding, also known as Port aggregation or link aggregation, means that multiple network interfaces (NICs) are combined into a single link, providing high availability, load balancing, maximum throughput, or these combinations. Note that bonding can only provide link monitoring, i.e. whether the link from the host to the switch is connected. If only the link of the switch to external (such as firewall, etc.) is down, and the

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

1 What is NIC bindingBind multiple network cards to the same IP address to provide services to the outside, can achieve high availability or load balancing. 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
