Exam 300-430 topic 1 question 274 discussion

Cisco Catalyst 9800 Series Wireless Controllers support local device profiling to classify wireless clients based on specific attributes. The two most effective profiling methods for identifying device types are: DHCP Profiling (D) 🏆 The WLC inspects DHCP request packets from clients. The DHCP Option 55 (Parameter Request List) and Option 60 (Vendor Class Identifier) contain device-specific information. This helps classify clients as iPhones, Android devices, Windows PCs, printers, etc. MAC Address OUI (E) 🔍 The Organizationally Unique Identifier (OUI) is the first 24 bits of a device’s MAC address and is assigned to manufacturers (e.g., Apple, Samsung, Cisco). The WLC uses this information to categorize devices by vendor.

To identify the types of devices on the wireless network using local device profiling on a Cisco Catalyst 9800 Series Wireless Controller, the following profiling methods must be used: Wireless Supplicant: The wireless supplicant (e.g., the software on the client device that handles wireless connectivity) provides information about the device type, operating system, and other attributes. This information can be used to profile the device. MAC Address OUI: The MAC Address OUI (Organizationally Unique Identifier) is the first three bytes of a MAC address and identifies the manufacturer of the device. This can be used to determine the type of device (e.g., Apple, Samsung, Dell).
