Cisco IOS image names are highly structured. Breaking down this specific filename provides insight into its functionality:

(Fat) image rather than a "Lightweight" (k9w8) one. Autonomous images allow the access point to function as a standalone device, managing its own security policies and radio configurations without requiring a central Wireless LAN Controller (WLC). Versioning and Stability The numeric string "153-3.jf15" corresponds to Cisco IOS Release 15.3(3)JF15
