Hello, I need some help to fully understand what license I need to buy for our first ISE purchase. Currently we are using Cisco ACS 5.x and I'm planning to migrate to a more recent product. I'm oriented to ISE because looks like the natural successor to ACS.
I'm not sure about what license can give me access to the old DACL, of which we make a great use. Features that we use are:
authentication to multiple firewalls and switches
Please note that the first 3 features are used by us with AnyConnect as well.
And given that I'm not very familiar with this technology and given the complexity of ISE licensing, I demand your help to figure out what license fits me bets between Premier, Advantage and Essentials.
