VLAN is based on the IEEE 802.1q standard and operates on the second layer of the OSI model, the Protocol Data Unit (PDU) of which is frame. With VLAN, you can logically divide networks that exist in the same physical environment. VLAN IDs can be set from 1 to 4094 (the values are reserved). The VLAN ID is the identifier of a VLAN (Virtual Local Area Network) that is used for VLAN tagging. For storage and vMotion networks, you will need to connect a VMkernel adapter that can have a different IP address for each network. For example, in the sceenshot below, the вЂњVM NetworkвЂќ created by default is a port group for guest virtual machines, while the вЂњManagement NetworkвЂќ is a port group for the EXSi hostвЂ™s VMkernel network adapter, with which you can manage the ESXi. Each port group has unique network label.

This approach can make it easier to manage large networks.ДЄ Port Group is an aggregation of multiple ports for common configuration and VM connection. You can make a segmented network on an existing vSwitch by creating port groups for different VM groups. The schema below shows the network connections of VMs residing on an ESXi host, vSwitches, physical switches, and shared storage. If a malefactor could access one of the virtual machines in one vSwitchвЂ™s network, he or she would be unable to access the shared storage connected to the separate network and vSwitch, even if they resided on the same ESXi host.

vMotion network for live migration of virtual machines between ESXi hosts.

Connecting storage, such as NAS or SAN, to ESXi hosts.

You might want to create a separate network with a vSwitch and physical NIC for performance and/or security reasons in the following cases: A vSwitch uses a physical network adapter (also called NIC - Network Interface Controller) of the ESXi host for connection to the physical network. vSwitches are used for ensuring connections between virtual machines as well as connecting virtual and physical networks. VMwareвЂ™s virtual switches are called vSwitches.

Cannot create a network loop for redundant network connection.

Does not participate in Spanning Tree protocols.

Does not learn the MAC addresses of transit traffic from the external network.

Namely, unlike physical switches, a virtual switch: A virtual switch ensures the same functions as a regular switch, with the exception of some advanced functionalities.

Definition of vSwitchДЄ virtual switch is a software program вЂ“ a logical switching fabric that emulates a switch as a layer-2 network device. TodayвЂ™s blog post explores the use of VMware virtual switches on VMware ESXi hosts for virtual machine network connections. VMnet8 NAT network вЂ“ uses a separate subnet behind the NAT, and allows connection of the VMвЂ™s virtual adapter through the NAT to the same network as the physical hostвЂ™s adapter.Д®SXi hosts also have virtual switches, but their settings are different.VMnet1 Host Only network вЂ“ allows connection to a host only, by using a different subnet.VMnet0 Bridged network вЂ“ allows connection of a VMвЂ™s virtual network adapter to the same network as the physical hostвЂ™s network adapter.Each of them uses a different virtual switch: If you have used VMs running on VMware Workstation, you may be familiar with three default virtual networks. The difference is that the VMs use virtual network adapters and virtual switches to establish connections with physical networks. Virtual machines connect to a network much in the same way physical ones do.
