An identity group is a collection of client identity variables. Each client identity in the group is set a value indicating its priority when device fingerprinting.
Device fingerprinting relies on specific information sent by a client when acquiring an IP address and configuration information from a DHCP server. Device fingerprinting uses the DHCP options sent by the wireless client in DHCP request or discover packets to derive a signature specific to a device class. For example, Apple devices have a different signature from Android devices. The signature is used to classify the devices and assign permissions and restrictions on each class.
To configure a client identity group:
Client identity group policies configure the signatures used to identify clients and use the signatures to classify and assign network access permissions.
