l In V200R009 and later versions:
Scenario 1: If no member switches in the CSS or stack system have applied for or installed a license, you need to apply for a license that contains ESNs of all the member switches.
Scenario 2: If all member switches in the CSS or stack system have applied for a license but have not installed the license, check whether the control items of all the license files are the same.
n If the control items of all the license files are the same, split the CSS or stack system, load each standalone member switch with their respective licenses, and then set up a CSS or stack system again. Alternatively, apply for a license that contains ESNs of all the member switches through the ESN change process.
n If the control items of all the license files are different, apply for a license that contains ESNs of all the member switches through the ESN change process.
l In versions prior to V200R009, you need to apply for a license that contains ESNs of all the member switches for the CSS or stack system.
