setting ip/ipv6 Configuration failed: {'IP configuration not allowed',}

Today, I tried to change IP Address via GUI method. I'm getting error " setting ip/ipv6 configuration failed: {'IP configuration not allowed',}"

When I tried to run command on command line it was fixed the issue.

Please follow below steps to resolve the issue.

> Take vCenter VM console on webbrowser.

> Press ALT+ F1 to go to command prompt and enter root credentials.

>  Shell

>  Type vami command located /opt/vmware/share/vami/vami_config_net and press enter to change IP

I want to change IP address of vCenter VM. Here I will type 6 number for IP address change. Next chagne the gateway and choose option 2.

it will show the current configuration and exit this program using 1 number in menu.
