Port Groups By applying a network policy to a port group, one can enforce security and traffic shaping rules. Additionally, if you have VLANs set up on your physical switches, you can assign a VLAN ID to a port group such that any VM on it will, for all intents and purposes, reside on that specific VLAN.

What is the purpose of a port group?
Port groups aggregate multiple ports under a common configuration and provide a stable anchor point for virtual machines connecting to labeled networks. Each port group is identified by a network label, which is unique to the current host. All members of a port group share common attributes like a VLAN tag.
What is uplink port group?
An uplink port group or dvuplink port group is defined during the creation of the distributed switch and can have one or more uplinks. An uplink is a template that you use to configure physical connections of hosts as well as failover and load balancing policies.
What are the two types of port groups in ESXi?
By default, there is one virtual switch on an ESXi host, with two port groups – VM Network and Management Network.
How do I add a port group to a distributed switch?
- In the vSphere Client, navigate to a data center.
- In the navigator, right-click the distributed switch and select Distributed Port Group > New Distributed Port Group.
- Create a port group for the NSX Edge uplink.
- Configure VLAN Type as VLAN Trunking.
Is a port group like a VLAN?
A portgroup is a part of vSwitch that can have specific policy (for shaping, security, teaming, …) and can be tagged to a specific VLAN. A VLAN is a logical network that has his own broadcast domain.
How do I make a port group in a standard switch?
- Select Virtual machine Port group for a standard vSwitch.
- Select vswitch depends on your requirement .
- Enter the network label for new port group .
- Click Finish to create the virtual machine port group.
- Here you can see the newly created port group.
What is the difference between port group and VMkernel?
The big difference between a Virtual Machine port group and a VMkernel port group is the type of traffic it is passing. As you can see, a VMkernel port is passing traffic specific to VMware vSphere. A virtual machine port group is just passing your garden variety virtual machine traffic.
What is port Group and types?
There are two generic types of port group as follows, Virtual machine – This port groups is for guest virtual machines. VMkernel – This port groups are for ESXi management functions and storage.
What is the difference between Vmnic and Vmknic?
VMKNIC – A virtual network interfaces, used by the VMKernel. This is used for traffic such as VMware management, vMotion, storage etc. VMNIC – The real physical interface on the ESX host.
How do I create a uplink port group?
- Name – change the name to Uplink-01 and click NEXT.
- Port binding – select Ephemeral – no binding.
- VLAN type – select VLAN trunking.
- VLAN trunk range – 0-4094 (default)
- Click NEXT > FINISH .
How many uplinks are needed for a distributed switch?
Provide at least one uplink for the distributed switch, keep IO control enabled, and provide a meaningful name for the default port group. Note that it is not mandatory to create the default port group. The port group can be manually created later. By default, four uplinks are created.
What is the VMkernel port used for?
What is a VMkernel port? The VMkernel port is a virtual adapter; that is, it is a special device with which the vSphere host communicates with the outside world. Thus, any service at the second or third level is delivered to the vSphere host. The VMkernel Networking Layer allows you to connect to the host.
What are the 3 port groups in VMware?
- Service console port group.
- VMkernel Port group.
- Virtual machine port group.
Can VMs on different port groups communicate?
Virtual machines on different vSwitches won’t be able to communicate with each other. Create separate port groups on the same vSwitch and assign each port group a different VLAN ID.
What are VMware port groups?
VM port groups are a way that we can create logical rules around the virtual ports that are made available to VMs. It’s common to create a port group for each VLAN and network subnet that you want to present to your VMs.
Can a port group have multiple VLANs?
No, in VST only one VLAN is allowed by port group, but you can create multiple port groups in one vswitch and setup one VLAN for each port group.
How do I make a vDS switch?
- Login to vSphere Web Client. Go to Networking.
- Provide the name for your new vDS.
- Choose the version for your new vDS.
- Here you can specify some of settings for your new vDS.
- Review all the configuration & click Finish to create new vSphere Distributed Switch.
How do I create an ephemeral port group?
Create a new ephemeral port group for the vCSA recovery Specify a Name of the port group to create, then click Next. From the Port binding drop-down menu select Ephemeral – no binding option. Specify also a VLAN type and VLAN ID if used then click Next. Click Finish to create a new Ephemeral port group.
What is virtual port group?
In Contrail Networking, a virtual port group (VPG) is a group of one or more physical interfaces attached to one or more virtual network interfaces. Each virtual network interface object corresponds to a VLAN ID and is attached to a Virtual Network (VN).
How does VLAN tagging work?
VLAN tagging is performed by the putting the VLAN ID into a header to identify which network it is present in. This helps in determining which interface or broadcast area the information packet needs to be sent to in order to receive the right information.
What is the difference between standard switch and distributed switch?
A standard vSwitch works within one ESX/ESXi host only. Distributed vSwitches allow different hosts to use the switch as long as they exist within the same host cluster. A distributed vSwitch extends its ports and management across all the servers in a cluster, supporting up to 500 hosts per distributed switch.
How do I add a VLAN to Dvswitch?
To add a PVLAN, right-click on the distributed switch and select settings and then edit private VLAN. By clicking the “+” signs you can add the Primary VLAN ID as well as the Secondary VLANs and types.
How do I change the port group in vSwitch?
To move a port group from one vSwitch to another, you simply change which /net/vswitch/child[XXXX]/ node it is under, making sure to respect what portgroup children are already there. In other words, once you move a port group to another vSwitch, you might need to change its child number.
What is VMkernel in VMware?
VMkernel is a POSIX (Portable Operating System Interface)-like operating system (OS) developed by VMware. It acts as a liaison between virtual machines (VMs) and the physical hardware that supports them, such as ESXi hosts. A VM needs VMkernel to communicate with the ESXi server.
