# esxcfg-vswitch -C VM_Traffic_on_VLAN100
The return code 1 indicates that VM_Traffic_on_VLAN100 portgroup already exists: To check if the port group already exists on the vSwitch use the following commands: The return code 0 indicates that vSwitch5 is not present. The return code 1 indicates that vSwitch0 already exists: To check if a virtual switch already exists, use the -c option as shown below. # esxcli network vswitch standard portgroup add -p VM_Traffic_on_VLAN120 -v vSwitch1 On ESXi, do the following to create port groups using esxcli command: View the portgroups that were just created above: # esxcfg-vswitch vSwitch1 -v 100 -p "VM_Traffic_on_VLAN100" # esxcfg-vswitch -A VM_Traffic_on_VLAN100 vSwitch1
# esxcfg-vswitch vSwitch1 -v 120 -p "VM_Traffic_on_VLAN120" # esxcfg-vswitch -A VM_Traffic_on_VLAN120 vSwitch1 On ESX, do the following to create port groups: The syntax to assign a VLAN to the port group is: In general, VLAN ID 0 disables the VLAN tagging on port group.
In the following example, you will see how to create the port groups and assign the VLAN to the portgroups. This is the endpoint network for your virtual machines. Every Port group has a name called Network label. It is also logical segmentation of vSwitch. Port groups are nothing but a group a ports on vSwitch. Next we will see how to create port groups. # esxcli network vswitch standard uplink add -u vmnic1 -v vSwitch1 On ESXi, execute the following command to add uplink: But, in order to associate a network port (add a uplink) to this virtual switch, use the following syntax: On ESX: We just created the virtual switch. When two or more virtual machines connected to the same vswitch the traffic between them is routed locally and whenever it needs to connect to the outside world, the traffic is routed through the uplink adapter basically a NIC port attached to the virtual switch. The maximum number of vSwithces that can be created on a single ESXi host is 127. The default number of logical ports on vswitch is 56. # esxcli network vswitch standard add -v vSwitch1 If you are on ESXi host, you can also use esxcli command as shown below to add a new switch. In this example, a new virtual switch vswitch1 is created: To add a new vswitch, use the -a option as shown below. By default, each ESXi host has one virtual switch called vSwitch0. On ESXi: Instead of esxcfg-vswitch, you can also use esxcli command to list vSwitches in ESXi as shown below. PortGroup Name VLAN ID Used Ports Uplinks Switch Name Num Ports Used Ports Configured Ports MTU Uplinks This will display both the switch and portgroup information. On ESX: To view all the current vSwitches in ESX server, use the -l option as shown below. This article explains how to configure vSwitch from CLI using esxcfg-vswitch command examples. The CLI configuration are very helpful when you are installing multiple ESX servers and planning to script the vSwitch configuration. VSwitch is also known as vSphere standard switch.

If you need to delete Vlan 100, type the following: To configure the switch I used the following commands: This allows my any virtual machine connected to the TrippLite port group to manage the TrippLite device. To ensure that the TrippLite device network traffic is on VLAN 100, I have configured port 0/37 so that it automatically puts “untagged” traffic on VLAN 100. Unfortunately, VLAN tagging is not supported on the TrippLite device which prevents me from having it’s traffic “tagged” with VLAN 100 before it arrives at the switch.
I connected a TrippLite Serial Port/Terminal Server to port 0/37 on the S55 switch. Once the traffic arrives at switch port 0/48 or 0/49 it will be sent out any other ports on VLAN 100 – in this configuration those ports are 0/37 -40. I am “tagging” virtual machine network traffic at the Virtual Machine Port Group named TrippLite on my VMware Standard vSwitch (vSS).Īny virtual machine that is connected to the Virtual Machine Port Group TrippLite will have it’s traffic “tagged” with VLAN 100 before it leaves the ESXi host.
I’ve connected my ESXi host physical network adapters (vmnic0 and vmnic1) to ports 0/48 and 0/49. There are two types of Q Ports U for Untagged, and T for Tagged traffic. VLAN 1 is the default VLAN for the switch. In my case below, I have already created VLAN 100. Pay particular attention to the Q Ports section. Before you get started I would recommend that you get a list of the existing VLANs that have been created on the switch.
