Control Plane Policing (CoPP or CPP) in 
Hardware

Improves security on the switch by protecting the 
CPU from unnecessary traffic or DoS traffic, and 
by giving priority to important control plane and 
management traffic. Different types of control 
traffic are grouped together based on certain 
criteria and assigned to a CPU queue. CPU queues 
can be policed by configuring dedicated policers 
in hardware. 

You can use CLI configuration options to enable 
and disable CPU queues, to change the policer 
rate, and to set policer rates to default. 

(LAN Base, IP Base, IP Services)

Improved Switch Start Up Time

When compared to the boot-up time in Cisco IOS 
XE Denali 16.1.1, the time it takes to boot up the 
switch in Cisco IOS XE Denali 16.1.2 is now 
reduced by two minutes.

Smart Call-Home Version 1 and Version 2

Smart Call Home supports a web-based 
application and notification system, providing 
diagnostic and real-time alerts for better network 
and device management.

Embedded Packet Capture (EPC) and Enhanced 
EPC with Wireshark

Support for Embedded Packet Capture (on LAN 
Base) and Enhanced EPC with Wireshark (on IP 
Base and IP Services). EPC is an on-board packet 
capture facility that allows network 
administrators to capture packets flowing to, 
through, and from the device, and to analyze them 
locally or save and export them for offline 
analysis.

Radioactive Tracing and Conditional Debugging

Radioactive tracing provides the ability to stitch 
together a chain of execution for operations of 
interest across the system, at an increased 
verbosity level. Coupled with Conditional 
Debugging, this feature provides a single debug 
CLI to debug all execution contexts related to the 
condition, without having to be aware of the 
various processes that were part of the control 
flow for a feature and without having to issue 
debugs at these processes individually.
