        The Enabled License Level is the purchased license level. This is the maximum level at which this node can operate without purchasing a license level upgrade.
The Effective License Level is the operating license level. If a license level restriction is configured for this node, the effective license level may be lower than the enabled license level. All master-capable switches must be operated at the same effective license level.
