Description (partial)

After configuring VSS and reloading the switches, they refuse to come up in VSS mode saying "Current license level of LANBASE/LANBASECRYPTO does not support VSS".
********************* CAUTION ************************
*                                                    *
* Switch is booting up in VSS mode but the current   *
* license level of LANBASE/LANBASECRYPTO does not    *
* support VSS. Switch is being reloaded and          *
* subsequent autoboot is disabled.                   *
*                                                    *
* Please issue 'clear VS_SWITCH_NUMBER' at the       *
* rommon prompt and boot the switch in standalone    *
* mode and install the VSS supporting license on the *
* switch before converting it back to VSS.           *
To make them come up in VSS, we have to explicitly configure "license boot level entservices" and save config (even though the current license level and reboot level is seen as entservices) before issuing "switch convert mode virtual"

The valid license is required to be installed in device before to boot the device in VSS mode. In TAC set the build-in license is available, but it was not activated, i.e EULA has not been accepted. So the license will not be able to use. So it fall back to base license, i.e LANBASE. Which doesnt support VSS.
