: Indicates a "Universal" image containing the complete feature set. The k9 designation signifies that it includes strong cryptographic capabilities (such as SSH, SSL, HTTPS, and IPsec VPNs). The universal nature means that specific feature tiers (IP Base, Enterprise Services) are unlocked via software licenses (Right-To-Use or Product Authorization Keys) rather than downloading entirely different software files.

This software image is engineered for modular campus access and distribution switches. It primarily supports the following supervisor engines: (WS-X45-SUP7-E) Supervisor Engine 7L-E (WS-X45-SUP7L-E) Supervisor Engine 8-E (WS-X45-SUP8-E) Supervisor Engine 8L-E (WS-X45-SUP8L-E)
