MicroNugget: What is Control Plane Policing?

[@sublimehypocrisy]

This video was brilliant. I just spent hours researching this feature of Cisco Routers, and this video explained everything I needed to know in just a few minutes. Bravo.

Good gob as always! a MicroNugget on Loop Free Alternate would be cool... or maybe BPG PIC :D

Awesome video Keith. I'm a little confused as to the differences between Control Plane Policing and Control Plane Protection though? What is the difference as to me they both appear to be protecting the control plane by policing traffic?

[@KeithBarker]

Steven Polley From Cisco's documentation: "Starting with Cisco IOS Software release 12.4(4)T, Control Plane Protection (CPPr) can be used to restrict and/or police control plane traffic destined to the route processor of the Cisco IOS device. Although it is similar to Control Plane Policing (CoPP), CPPr has the ability to restrict/police traffic using finer granularity than that used by CoPP. CPPr divides the aggregate control plane into three separate control plane categories, known as subinterfaces: (1) host, (2) transit, and (3) CEF-exception. In addition, CPPr includes the following additional control plane protection features:The port-filtering feature provides for policing/dropping of packets going to closed or nonlistening TCP/UDP portsQueue thresholding limits the number of packets for a specified protocol that will be allowed in the control plane IP input queue"

+Keith Barker Brilliant, this is just what I was looking for. It seems to me that most companies would just use CPPr instead though as it can do all that CoPP can and in greater detail
