Changing the VLAN ID using the vSphere UI
- Click the ESXi host and click the Configure tab.
- Under Networking, select Virtual Standard Switches
- In the right panel, click on the PortGroup to be modified.
- Click on 3 dots next to PortGroup name & select Edit Settings
- Under Properties select the appropriate value in the VLAN ID field (enter 0 for no VLAN).
- Click OK.
To change the VLAN ID using the Esxi Host Client:
- Log into the Esxi host client with root credentials in the browser like "https://esxi-host.domain.com"
- In the left side under Networking, and select Virtual Standard Switch.
- In the vSwitch topology diagram of the switch, click the name of the port group.
- Click Edit under the topology diagram title.
- In the Properties section, Configure VLAN tagging in the VLAN ID drop-down menu.
To change the VLAN ID at the Esxi host using the command line
- Log into ESXi host as root via SSH, remote console, or at the physical console.

- To view the current configuration of the virtual switches, run the command:
esxcfg-vswitch -l
The output appears similar to:
Switch Name Num Ports Used Ports Configured Ports MTU Uplinks
vSwitch0 2990 3 128 8000 vmnic0
PortGroup Name VLAN ID Used Ports Uplinks
VM Network 110 0 vmnic0
Note: Your virtual switch and PortGroup names may be different.
- Record the name of the virtual switch and PortGroup that you want to change.
- To change the VLAN ID on a PortGroup, run the command:
- esxcfg-vswitch -p "portgroup_name" -v VLAN_ID virtual_switch_name
Where portgroup_name is the name of your portgroup, and virtual_switch_name is the name of your virtual switch.
For example, using the configuration above, to add a VLAN ID of 111 to VM Network (which resides on vSwitch0), you must run the command:
esxcfg-vswitch -p "VM Network" -v 111 vSwitch0
- To verify the new configuration, run the command:
esxcfg-vswitch -l
The output appears similar to:
Switch Name Num Ports Used Ports Configured Ports MTU Uplinks
vSwitch0 2990 3 128 8000 vmnic0
PortGroup Name VLAN ID Used Ports Uplinks
VM Network 111 0 vmnic0
To resolve connectivity and configuration issues, use these commands to link or unlink on Standard vSwitches:
-
- To unlink an uplink:
esxcfg-vswitch -U vmnic vSwitch
- To add an uplink:
esxcfg-vswitch -L vmnic vSwitch
