ISE 3.1 licensing

[Network-giiig]

Hello,

We have Cisco ISE 3.1, How do I know how many Cisco ISE-P-LIC (Premier) licenses do I need to deploy 500 users?? can't find how to count licenses anywhere.

Thanks in advance

Licensing for ISE 3.x is actually pretty straight forward. It's not based on users, it's based on the number of unique endpoints (mac addresses) that will be connected to the network at any given point. ISE maintains these sessions until an endpoint disconnects from the network or times out. 

The licensing has three tiers, Essential, Advantage, and Premier. The authorization features you use in ISE when authenticating these unique mac address/endpoints will determine which one of the licenses you need. 

Premier licenses will cover any endpoint authorized with Premier, Advantage, or Essentials features. 
Advantage licenses will cover any endpoint authorized with Advantage or Essentials features.
Essentials licenses will only cover endpoint authorizations with essentials features. 

The ISE ordering guide walks through the features and what tier they fall in to.
