Control Plane (CP): The control plane is a generic term used to group together the functions and traffic that involve the CPU of the Catalyst Switch.As an example, it controls how packets are delivered from the FED to the IOSd and vice versa
Packet Delivery System (PDS): This is the architecture and process of how packets are delivered to and from the various subsystems.It is run as a software process within the kernel IOSd: This is the Cisco IOS® daemon that runs on the Linux kernel.Forwarding Engine Driver (FED): This is the heart of the Cisco Catalyst switch and is responsible for all hardware programming/forwarding.Cisco IOS®-XE retains not only the same look and feel of the classic Cisco IOS®, but also its operation, support, and management. Cisco IOS® itself runs as a daemon within the Linux OS (IOSd). All of the subsystems that were inside Cisco IOS® before - such as the modules drivers, High Availability (HA), and so on - now run as software processes within the Linux Operating System (OS). With Cisco IOS®-XE, Cisco has moved to a Linux kernel and all of the subsystems have been broken down into processes. It is important to understand how Cisco IOS®-XE is built.
Additionally, this document introduces several new commands on this platform that are integral in order to troubleshoot such problems.

This document describes how to troubleshoot high CPU usage concerns, primarily due to interrupts, on the new Cisco IOS®-XE platforms that run 16.x releases (also referred to as Polaris).
