Standard switches for vmware esxi Basics

Summarize the virtual network of vmware workstation, and then compare the similarities and differences between the two:

1) There are three network types: Bridge, NAT, and Host-only;

2) The Bridge type can only Bridge one network card at a time. That is to say, there are several network cards on your computer (Logical Network Card, such as openvpn) that can only be built with several Bridge networks, of course, the total number cannot exceed 10;

3) Only one NAT type can be used;

4) multiple Host-only instances can be created and can only communicate with physical hosts;

5) both the NAT and Host-only types create a logical Nic on the Host for communication with the physical Host;

6) can only have the VMnet0-VMnet9 of these 10 networks. By default, VMnet0 is Bridge, VMnet1 is Host-only, VMnet8 is NAT, and 7 are unused. The default value is enough.

Next let's take a look at the Standard switch of vmware esxi:

1) No network type such as NA. I think it can be regarded as Host-only without binding any physical Nic;

2) Multiple Physical NICs can be bound for load balancing and fault tolerance, while only one network of workstation can be bound.

3) You can also do not bind any physical network card. In this way, the virtual machine on the vswitch cannot communicate with the outside world;

4) You can create multiple standard switches. The default port number is 120;

5) Virtual Machine traffic and management traffic (vMotion, HA, FT, etc.) are separated;

6) by default, a standard switch has only one port group. We can control a network policy for the port group. Multiple port groups can be created to implement different network policies for different virtual machines.
