Our use cases are based around dot1x. Basically wired and wireless authentication, authorization, and accounting.
In terms of administration, only our networking team uses this solution. Probably five to ten administrators manage the whole product. Their role pretty much is to make sure that we configure the use cases that we use ISE for — pretty much for authenticating users to the wired and wireless networks. We might have certain other advanced use cases depending on certain other business requirements, but their job is pretty much to make sure all the use cases work. If there are issues, if users are complaining, they log into ISE to troubleshoot those issues and have a look at the logs. They basically expand ISE to the rest of the network. There is ongoing activity there as well. The usage is administrative in nature, making sure the configurations are okay, deploying new use cases, and troubleshooting issues.
