Cisco ISE Licensing

[atiye.bigdeli]

Hi.

I want to buy license for Cisco ISE. I searched and found 3 different part number for Cisco ISE Virtual Machines:

small, medium and large. 

I dont know  shoud I order icense according to VM size or the Session counts?

best regard

go through the doc. you will get an idea.

It depends on session counts not on VM size

The licenses cover the different VM sizes. (Note there is also a new Extra Large VM as of ISE 2.4.) Which VM size you need depends on the size of your deployment.

ISE deployment design depends on a lot of things, most notably concurrent endpoints. I recommend having a look at the excellent Cisco Live presentation on "Designing ISE for Scale and High Availability". The latest version of that can be found here:
