Configure the VMware vSwitch Security Policy

Vswitches play an important role in protecting the security of virtual infrastructure. Therefore, you can learn how to apply the VMware vSwitch Security Configuration to minimize the chance of your virtual infrastructure being compromised. To protect the virtual network environment, you need to assess where is the most dangerous. Virtual machines that provide services to external users may be the most vulne

Basic vswitch: the initial vswitch settings cannot be ignored.

VswitchIt can work normally without going through the initial configuration and directly accessing the network. This is the development trend of switches. However, this is a relatively unprofessional approach. If the Initialization Configuration is not completed, it will be very unfavorable for troubleshooting and maintenance in the future. If you do not plan the name of a vswitch properly, it will be difficult to match the name of the

What is the difference between a vswitch and a vro? Can a vro be a vswitch?

Some friends often come to consult the hottest software station editor. If you know the difference between a vswitch and a vro, if you have used a vswitch and a vro at the same time, the biggest difference between a vswitch and a vro is that a dial-up Internet access can be achieved within the vro, and then the Internet can be accessed through sharing with multip

The difference between a traditional vswitch and a modern vswitch

The difference between a traditional vswitch and a modern vswitch Some vswitches on the market claim to have QoS Assurance. In fact, they only support single-level priority settings and do not form a loop logically. In the event of a fault, the backup link is enabled, I would like to share it with you here and hope it will be useful to you. We often mention that the traditional Ethernet switch is actually

Open VSwitch FAQ (i)

mirrorsQ:Does Open vSwitch Support Configuring a port in promiscuous mode?A:Yes. How do you configure it depends on the what are mean by "promiscuous mode": Conventionally, "promiscuous mode" is a feature of a network interface card. Ordinarily, a NIC passes to the CPU is only the packets actually destined to the IT host machine. It discards the rest to avoid wasting memory and CPU cycles. When promiscuous mode was enabled, however, it passes e

Vswitch configuration basics: static IP Address Configuration of vswitch VLAN Interface

VLANIt is a protocol proposed to solve Ethernet broadcast problems and security. It adds VLAN headers Based on Ethernet frames and divides users into smaller working groups using VLAN IDs, restrict mutual access between users in different working groups. Each working group is a virtual LAN. The following describes how to implement static VLAN interfaces of a switch.IPAddress Configuration. One Networking requirement: 1. SwitchA is a layer-3 switch, and PC1 and PC2 can communicate with each other

stopped development. The development of layer-3 switching technology and layer-3 switching equipment will certainly push forward the information revolution of the whole society in a deeper level and gain an increasingly important position in the entire network. Layer-3 switching technology with network service functions layer-3 switching technology through the layer-by-layer unlocking of each packet encapsulation, and identify the information at the application layer, in order to achieve conten

Enable VMwareESXi vswitch to support VLAN

Enable VMwareESXi vswitch to support VLAN Currently, virtualization is widely used. Generally, a physical host can create multiple virtual machines on a physical host after installing VMware ESXi or Hyper-V Virtual Machine Software, in addition, each created virtual machine can provide external services like the original physical machine, which can undoubtedly make full use of server resources to save power

Distributed vswitch Distributed Switches overview

Distributed vswitch must be defined at the data center level by vcenter, a super switch across multiple ESX hosts (supported only by the Enterprise Plus version), which logically composes a single switch distributed across multiple ESX hosts into a "big" switch , each ESX standard switch is configured separately, now vcenter distributed vswitch can be centrally configured and managed at the data center leve

Five major improvements to Hyper-V vswitch

Hyper-V vswitches have been significantly improved in Windows Server 2012 without additional costs. The following are five major improvements to Hyper-V vswitch expansion. 1. in Windows Server 2012, Cisco switches can be used to replace Hyper-V vswitches. It may not be appropriate to replace the word here, but you must be able to fully expand the vswitch. In Windows Server 2012, The Nexus V

How to configure the virtual Switch vswitch

When using a physical computer to connect to the physical switch through the physical network card to the network, on the virtual machine on a server usually has more than one network card, virtual machine directly and the virtual machine and the physical machine is how to network it? Under the VMware vsphere architecture, the servers will be virtualized out of the switch for use by virtual machines, and there are two virtual switches,

Hyper-v scalable vswitch
