Cisco Denali 16.1.1

This release note gives an overview of the features for the Cisco IOS XE Denali 16.1.x software on the 
Catalyst 3650 series switch. 

Unless otherwise noted, the terms switch and device refer to a standalone switch and to a switch stack.

The Catalyst 3650 switches are the next generation of enterprise class stackable access layer switches 
that provide full convergence between wired and wireless networks on a single platform. This 
convergence is built on the resilience of new and improved 160-Gbps StackWise-160. Wired and 
wireless security and wireless application visibility and control are natively built into the switch.

The Catalyst 3650 switches also support full IEEE 802.3 at Power over Ethernet Plus (PoE+), modular 
and field replaceable network modules, redundant fans, and power supplies. The Catalyst 3650 switches 
enhance productivity by enabling applications such as IP telephony, wireless, and video for a true 
borderless network experience.

For Cisco Catalyst 3850 Series Switches and Cisco Catalyst 3650 Series Switches, the Cisco IOS XE 
Release 3.7E has merged with the Cisco IOS XE Denali 16.1.x. Most features supported on Cisco IOS 
XE Release 3.7E are also supported on Cisco IOS XE Denali 16.1.x. For more information about features 
not supported in Cisco IOS XE Denali 16.1.x, see 

Cisco IOS XE Denali 16.1.x and Cisco IOS XE represent the continuing evolution of the preeminent 
Cisco IOS operating system. The Cisco IOS XE architecture and well-defined set of APIs extend the 
Cisco IOS software to improve portability across platforms and extensibility outside the Cisco IOS 
environment. The Cisco IOS XE software retains the same look and feel of the Cisco IOS software, while 
providing enhanced future-proofing and improved functionality.
