In a stack system, if only one switch's ESN is used to apply for a license, the license takes effect for the entire stack system after being activated. If the stack system splits, the switch whose ESN is used for license application is not affected, but new configurations related to licensed features cannot be added on the other switches in the stack. To prevent this problem, you are advised to apply for a license for all the switches in the stack system.

For details, see the CE Series Switches License Usage Guide.
