If this issue occurs, check the following ESX vSwitch VLAN settings:

• Ensure you are using the correct VLAN mode (EST or VST).
• If the physical switch is set to access port, ensure that the vMotion vSwitch VLAN ID is set to 0.
• If the physical switch is set to trunk mode, ensure that the proper VLAN ID is set on vMotion vSwitch.
• Utilize vSwitch CDP information to assess physical switch configuration.

When the settings are correct, retry the vMotion operation.
