Applicable to Entuity v19.0 upwards. If you are using an earlier version of Entuity, please see this article.
The Identity Services Engine (ISE) is a key component of the DNAC. Once taken under Entuity management, the ISE sends syslogs to Entuity that are then turned into events and incidents. In Entuity, ISE devices are managed as Ping Only.
To add an ISE device, you will need to add it as a basic management, Ping Only-type device. Please see this article on adding a device under basic management to Entuity. In the Asset Type dropdown field, select Ping Only.
