Additional General License Information

Software licenses are stored in the EEPROM and, after enabled, persist through reboots, software upgrades, power outages, and reconfigurations. The keys are unique to the switch, but can be transferred (see Transferring Licenses).

If you attempt to execute a command and you either do not have the required license or have reached the limits defined by the current license level, the system displays one of the following messages:

Error: This command cannot be executed at the current license level.
Error: You have reached the maximum limit for this feature at this license level.
