ESXI-06-000065 - All port groups must not be configured to VLAN values reserved by upstream physical switches.
Information
Certain physical switches reserve certain VLAN IDs for internal purposes and often disallow traffic configured to these values. For example, Cisco Catalyst switches typically reserve VLANs 1001-1024 and 4094, while Nexus switches typically reserve 3968-4047 and 4094. Check with the documentation for your specific switch. Using a reserved VLAN might result in a denial of service on the network.Solution
From the vSphere Client select the ESXi Host and go to Configuration >> Networking >> Select properties on the virtual switch >> Select the port group and click Edit. Change the VLAN ID to not be a reserved VLAN ID and click OK.or
From a PowerCLI command prompt while connected to the ESXi host run the following command:
Get-VirtualPortGroup -Name 'portgroup name' | Set-VirtualPortGroup -VLanId 'New VLAN#'
