Differences for the different ISE VM License bundles?

[cnegrete]

Hi everyone.

I'm trying to quote a group of VM ISE servers and I'm not quite sure of the license we need:

Found on https://www.cisco.com/c/en/us/products/collateral/security/identity-services-engine/eos-eol-notice-c51-738715.html that the ISE-VM-K9= license is on End of Sale. So, the first question is, is this ISE-VM-K9= the same as R-ISE-VM-K9= that exists on the Legacy section of the ordering guide (table 17)?

Now, assuming that the R-ISE-VM-K9= license is still purchasable, I assume I can order this SKU and install whichever VM deployment I want (small, medium, large) provided I have the software?

And if I can do the second question, what's the reason of having the R-ISE-VM-K9=, and the sized R-ISE-VMS-K9=, R-ISE-VMM-K9= and R-ISE-VML-K9= SKUs?

I'd need the large deployment SKUs, by the way.

Thanks for your time.

Yes the number of active sessions plays into the size of your deployment. Regardless a small deployment running all personas is supported. Please reference Cisco Live Orlando and the Performance and scale numbers here, they are from the ISE Business Unit directly. If you're seeing issues please of course work through the TAC
