As per the NSight Deployment
every device managed by NSight server must have a license
The NSight feature is a licensable feature which follows a subscription model.
The license key comprises of two key parameters: device count & expiry date:
Device count: The count should be equal or more than the number of managed devices in the network, and is
a sum of the total number of Access Points and Controllers.
Expiry Date: The licenses are valid till the expiry date specified on the licenses. The Licenses are available for a
period of 1 to 3 years.
If the license count is insufficient or the licenses have expired, a warning message is displayed on the NSight UI
for a period of 60 days, as shown below. After 60 days, the NSight User Interface is shut down. After the UI is
shut down, NSight server will continue to collect statistics and write information to the database. Once
required licenses will be added NSight UI will resume normal operation.
