Restrictions for Configuring Licenses
Members of a switch stack must run the same license level (base license level and add-on). If the license level is different with a mismatched base license, the switch will not join the stack until it is changed and rebooted from the active stack. Mismatched addon licenses are automatically synced by the active stack.
A permanent license can be moved from one device to another. To activate a license, you must reboot your switch.
An expired evaluation license cannot be reactivated after reboot.
