Hi
Yes there's an integration between firepower and ISE. It'll use pxgrid which requires plus licenses.
This will allow you to see user and not only IP. In ise, firepower will leverage passive id.
Take a look here:
https://www.cisco.com/c/en/us/td/docs/security/firepower/620/configuration/guide/fpmc-config-guide-v62/user_identity_sources.html
Within ISE, you have multiple way to manage guest access.
Yes you can have sponsor creating guest accounts and send their credentials over email or text. You can also do guest self registration and they'll get their credentials right away on the screen and/or receive them on their email inbox or text.
Instead of sending credentials, when a sponsor create accounts, you can also decide to print them out and then distribute to your users.
When you create a guest user it even when they create themselves their account, a guest profile is attached to them which says the number of hours and schedule when they can temporary access Internet. I recommend taking a look on Cisco community ise documentation where you'll find some documentation help.
You don't need cmx for this. Cmx is to leverage localization for example.
Does this classify your questions?
Thanks
Francesco
