ISE clustering & licensing

[EvaldasOu]

Hello Experts.

Could you help me to know, if we wan't to make a cluster from physical or virtual ISE servers, do we need to use separate licensing also?

I mean to we need to buy the same licenses for the secondary server, as it is on primary?

The license applies to all the servers in a deployment. They are installed on the primary and apply for connected secondaries too

No you don’t need to buy additional licenses. The licenses that you  apply on the primary servers will be applicable to all the ISE devices  connected to the primary ISE device.
