The virtual machine port group of the virtual standard switch is connected to the virtual network.
You can add or modify a virtual machine port group from vSphereClient: The Add Network wizard of vSphereClient walks you through the task of creating a virtual network connected to a virtual machine, including creating a vSphere standard switch and configuring network label settings. When you set up a virtual machine network, you need to consider whether to migrate the network between hosts.
Principles of Virtual Networking:
Use tunnels to create a virtual network on top of a traditional car-split (Ethernet) physical network. Network virtualization utilizes protocols such as VXLAN or NVGRE to provide Layer 3 network tunneling and allow virtual machines (VMs) to be migrated between networks within a data center or between data centers.
SDN and network virtualization collisions are highly related technologies with overlapping capabilities, especially within the data center. Both have a wide variety of (complex) cost models, and the deployment of both technologies needs to be driven by specific use cases and may require a lot of customization to be used in your environment.

Port mirroring is a very important function in network equipment, which plays a role in management and monitoring, and also plays a certain role in the security of the device, (monitoring the packet information circulated by an important network device to prevent the occurrence of events that are not conducive to network security).
Port mirroring is divided into local port mirroring (SPAN) and remote port mirroring (RSPAN).
Local port mirroring: The mirrored port of the mirrored port is not on the same device, which can cross the network, making it more convenient for network administrators to manage remote switch devices.
Configuration of port mirroring:
1.Inbound indicates that the packets accepted by the port are mirrored, outbound indicates that the packets sent by the port are mirrored, and both the packets received and sent by the port are mirrored.
2.Determine the destination port of the mirror.
To implement remote port mirroring, you need to configure a special VLAN, called a remote-probe VLAN, through which all mirrored packets are transmitted to the mirrored port of the destination switch.
Source switch: The switch where the monitored port is located, which is responsible for sending mirrored traffic up to the intermediate switch or destination switch through the remote-probe VLAN.
Intermediate Switch: The switch between the source switch and the destination switch, which is responsible for sending mirrored traffic to the next intermediate switch or destination switch through the remote-probe VLAN.
Destination Switch: The switch where the detection port is located and sends the received traffic to the detection device through the mirrored destination port**.

Switches, routers, network security appliances are all fine.
It's usually on the side of the firewall.

1.The switch hardware and software support the port mirroring command.
2.The account and password you have have the permission to configure port mirroring command 3If it is an independent switch, you need to mirror the captured traffic on at least one idle interface, and find a PC or traffic capture device to receive the captured image wine.
4.If multiple switches are interconnected and the switch does not have extra free ports, you can mirror the traffic to the free ports on other switches.
Scold. The switch works in much the same way as the wire collector you are talking about. >>>More
The broadband network cable of the telecom is directly connected to the switch (if it is ADSL, it is also the same to connect the modem to the switch), and the host IP setting method for dial-up Internet access first: see the local connection in the network connection, click on the right health selection properties, and click the Internet Protocol (ICP IP) attribute before the icon in the notification area after the connection, and click to use the following IP address: IP address to fill in: >>>More
Normally, broadcasts can only be isolated by dividing subnets, but the advent of VLANs broke this law, and it was strange to solve the Layer 3 problem with Layer 2 stuff, but it did. VLAN Chinese called virtual local area network, its role is to logically divide the physically interconnected network into a number of unrelated networks, these networks are unable to communicate with each other, as if there is no connection between each other, so the broadcast is also separated. >>>More
Layer 2 is a common switch.

I can remember the other one that could be picked up.
